Welcome to issue 48 of Regulation Roundup. We are all finding ways to transition to new working arrangements during this challenging period. Most of the roadshows have now been completed and we were fortunate to be able to hold some of the roadshows in person. I note that Regulation Roundup is still packed with very helpful information concerning the latest developments in the industry. It is one of

our most useful means to get information out to the industry in a form that is designed to be understood and informative to the trades. We are always looking for ways to improve the publication and are always looking for feedback from industry. The electronic format gives us greater flexibility as we are no longer limited by the constraints of having to mail out the publication. As always I really encourage you to have a read of Regulation Roundup as it is designed to help everyone in the industry.

Solar Battery Electrical

Extra Low Voltage (ELV) and the ECOCThere seems to be a misconception by electrical

workers around the requirements of completing an ECOC when installing ELV wiring and equipment,

and that an ECOC is not required.

This is not correct.If the ELV wiring forms part of a fixed installation and draws in any requirements around additional

protection, installation conditions, verification and testing covered in AS3000

then an ECOC is required.

ELV cabling may be installed by an unlicensed worker, but an unlicensed worker cannot provide a

certificate of compliance to certify the installation.

This means if you’re an Electrician and installing ELV systems in any fixed installation, then you must submit an ECOC covering the installation.

REGULATION ROUNDUP | 5

Electronic–Certificates of Compliance and Revenue Metering EquipmentRequired to be issued for each installation where electrical work is performed including the installation of revenue metering. The Technical Regulator requires an electronic copy or hard copy to be provided to the customer within 30 days of the installation being energised or being made ready for energisation. Regarding meter installations the e-COC must be completed by the installer at the time of connecting the

meter. Business cards with the e-COC number left in the metering switchboard are not a substitute for the owner receiving a completed copy and will be treated the same as not supplying an e-COC in the required timeframe. Further, electrical installations such as a group of residential townhouses or a block of warehouse’s require an e-COC for each separately metered part of the installation.

In this case unlike a new install we don’t know if the Meter Isolator is actually connected. If the installing electrician

prior to the meter being upgraded locks it out with a tag the occupier is less likely to be confused. A few electrical workers

have been caught out by this thinking they have isolated the power.

Always test your isolation is effective.

Labelling of Meter Isolators and Main SwitchesWhen a new Meter Isolator is installed it is important to remember that it controls the entire installation. This then requires the “Meter Isolator” to also be labelled as a “MAIN SWITCH”. In addition, all new alternative supplies (solar,

battery, generator etc) will need to be labelled as a Main Switch, e.g. for a solar inverter “SOLAR SUPPLY MAIN

SWITCH”. Because the addition of an alternative supply and Meter Isolator, labelling in the switchboard may now

need to be reconfigured. The Old Main Switch is now only considered as a “Main Isolator” and shall be labelled accordingly.

Where on an existing installation a Meter Isolator is attached to a switchboard but not electrically connected (ready for the meter installer) the installing electrical worker must label this switch as not in use do not operate. An example is to add an out of service tag and cable tie to the lock off facility. As the meter installer is energising this part of the installation, they are responsible to affix the correct labels when electrically connecting the Meter Isolator. This will minimise the risk of someone mistakenly thinking the newly installed Meter Isolator will isolate the electrical installation when it hasn’t even been connected yet.

Main Switch to be relabelled. MAIN ISOLATOR

This needs to be labelled as NORMAL SUPPLY MAIN SWITCH

DEM staff from the Office of the Technical Regulator’s electrical division are sad to announce the retirement of an icon in the electrical industry Charlie Hoare. Charlie has some 50 years’ experience in the electrical industry including over 25 years with the Electricity Trust of South Australia where he started his electrical career on the 6th January 1971 and left there when in 1997 ETSA was privatised. Electrical Contracting

for several years, he then joined this office and accrued over 20 years again serving the people of South Australia, in particular the electrical

industry. His 20-year stint in the OTR has been enthusiastic and entertaining, his antics will be missed. Charlie had been involved in

multiple electrical Australian standards committee’s over the years including AS/NZS 3000 (Wiring rules) and being chairman of many other

reference standards. His depth and breadth of knowledge especially in relation to electrical standards was a rare treasure. Charlie will be missed by many in the electrical industry especially those in the OTR.

We wish Charlie & Bev all the best for a fabulous retirement. They can now spend more time with the family, getting the tides right to get the boat out and terrorising the streets of the Copper Coast riding his Triumph motorbike – I sense a new project coming up.

Dave Schrapel

End Of An Era

We at the OTR would like to welcome Kevin Coates to the Electrical auditing team.

Previously Kevin worked as an Electrician in the Energy Metering Sector for Total Metering Services.

He also worked for 3 years at NHP, working closely with Power Distribution products and PLC automation systems (Allen Bradley).

Kevin’s experience and knowledge from another different facet of the electrical industry will be a real asset to the group. Kevin is keen to help develop many parts of the industry as technology progresses. He is very excited to be working with and learning from like-minded people in his new role as an Electrical Technical Standards and Safety Officer with the OTR.

The OTR has found several solar installations where the earth clamp is touching the underside of the solar module. This could damage the solar panel and cause an earth fault. There are multiple modules on the market that have various depths, because of this it is important to check with manufacturer’s instructions that your modules are compatible with your racking system.

SERVICE AND INSTALLATION RULES REVIEW

SA Power Networks needs your help:SA Power Networks is undertaking a critical review of the Service and Installation Rules (SIR). These Rules are used to facilitate the safe reliable connection and on-going operation, to the Electricity Distribution Network across South Australia.

The key objective of this review is to work with industry to simplify the Rules for all users. This will be achieved by:

• Ensuring the Rules provide value to our customers – enabling accurate and flexible solutions

• Simplifying the Rules to ensure they are consistent and can be clearly communicated

• Eliminating barriers with a “One Team” approach to develop a suite of Rules which are not viewed as a SA Power Networks document but as a whole industry document.

Have your saySA Power Networks values input from all parties and will review all suggestions, comments, and feedback. We want to understand:

• What are your key pain points?

• What do you like about the current SIR?

• What’s not working with the current SIR?

• Do you have any suggested omissions/ additions?

• Is the layout/structure of the document appropriate?

• Are there any gaps?

Please lodge your feedback to SIR@sapowernetworks.com.au by 30th September 2021.

We are presently reviewing feedback received from electricians which attended the recent NECA Roadshows and the Master Electricians Australia (MEA) branch meeting. At this stage, we are halfway through the review process incorporating this feedback from electricians and the industry.

TimeframeThe review will be undertaken during 2021, for releasing to the industry in early January 2022.

If you have any queries regarding the review, please contact SA Power Networks Customer Solutions Manager, Mr James Case on 0403 582 220.

[ Hoses Melting Due To Possible SAPN Earth Issue ]Gasfitters please make sure that you undertake electrical safety checks before servicing or disconnecting gas appliances for replacement or repairs. There have been a number of plumbing and gas installations affected by faulty electrical installations or incoming consumer network supply feeds that has caused bonded metallic gas and water plumbing installations to become live when appliances or pipe sections are disconnected because there is no longer a current return path via the bonded water or gas service to earth.

In a recent case a flexible gas hose with stainless braided sleeving melted and caught fire. The fault was traced to a break in the neutral feed to the property so the electrical current fed back the source of generation via the earth and bonded pipe systems. Over the years we have had cases where plumbers and gas fitters have received electric shocks disconnecting hot water heaters, or gas and water pipes. To avoid this situation installers are advised to check for AC voltage and always use bonding straps to maintain electrical continuity through metallic pipes before disconnecting appliances or cutting services.

When it comes to pressure testing gas installations gas contractors and workers should refer ASNZS 5601.1-2013, tables D1 and E2 for pressure test information. Ask yourself:

¶ Am I performing correct pressure tests for my application?

¶ Am I using the appropriate testing equipment for my circumstances?

¶ Am I testing for the correct duration?

¶ Does a 5 minute test duration per 30 litres of pipe volume apply to all gas installations?

¶ Is my pressure test equipment suitable for all pipe volumes and pressure ranges?

• Table D1 will assist you determine the estimated pipe volume for your installation. For example;

¶ 70m of 25mm copper is approximately 30 ltr of volume

¶ 70m of 80mm copper is approximately 300 ltr of volume

• Table E2 specifies instrument types, limitations and test times. The table can be summarised as follows;

¶ Bubble detector suitable for up to 3 kPa, max volume 30 litres test duration 5 minutes.

¶Water manometer suitable for up to 10 kPa, max volume 300 litres test duration 5 min for each 30 litres or part thereof.

¶ Digital manometer suitable for up to 200 kPa, max volume 300 litres test duration 5 min for each 30 litres or part thereof.

¶ Single column compensated gauge, (Kuhlman) suitable for up to 70 kPa, max volume 300 litres test duration 5 minutes.

¶ Electronic transducer pressure gauge or recorder with data or chart recording output, suitable for up to 700 kPa, installation volume unlimited test duration 12 to 24 hours as required.

• In summary;

1. check / determine the volume of gas installation to be tested, then

2. determine the pressure limit for your test, i.e. 1.5 times the operating pressure or 7 kPa or the EOP, whichever is the greater

3. ensure you have the correct instrument

4. determine the duration of the test

5. Follow the procedures outlined in Appendix E Testing for Gas Tightness.

[ Pressure Test Procedures ]

Change of Type B Authorised CertifierThe OTR reminds gas fitters that all installed type B gas appliances require individual certification to satisfy

the requirements of the Gas Act 1997. The OTR accredits private Type B certifiers to perform desktop design reviews, on site testing and certification of Type B to the AS3814, Industrial and Commercial Gas Fired

Appliancs Standard.

Currently there are 2 accredited certifiers in South Australia, the first being TG Certification and the second being AusNet Transmission Group Pty Ltd trading as Mondo. Mondo have advised the OTR that they have sold part of their operations to the Australian Gas Association (AGA) Limited and that Mondo

will cease providing type B certification services after the 15th August 2021.

The AGA have acquired equipment, records, and processes from AusNet to provide this service and specialist AusNet type B staff will transfer to the AGA to continue performing this role. The AGA have

successfully applied to the OTR for authorisation to provide type B certification in South Australia as of the 16th August 2021.

From the 16th August type B applications for appliance certification can be made with either; TG Certification or the AGA limited. OTR documents outlining type B requirements will be modified and available upon request to provide the details of TG Certification and the new details for contacting AGA.

Some of the appointed authorised officers employed by Mondo will now be employed/contracted by AGA, including those locally within Gassupport, so it should be business as usual under a new brand.

Here are just some examples of gas appliances in need of a service. The photos show an air circulation fan and wiring looms ‘clogged’ up with years of dust, pet hair and household fibres. Not only will this kind of foreign material impede how the appliance can operate, it is also a significant fire hazard.

Manufacturer’s generally recommend appliances be serviced every two years. A brief visual inspection may be all you need to advise the owner a service is required. When servicing an appliance, if it allows you to check the functional operation as the manufacturer intended.

You also have an obligation to check burner pressures. Remember, if additional appliances have been added over the years, there may not be enough gas pressure to run all appliances simultaneously as required by the Standard.

The minimum supply pressure at the inlet to the gas valve should be 1.13kPa for NG and 2.75kPa for LPG unless otherwise stated. If you are servicing any open flued appliances, you must check for spillage with all household exhaust fans running and external doors closed as part of commissioning. See appendix R in AS/NZS5601.1:2013

Servicing Gas Equipment

Don’t assume the settings on a factory set / sealed appliance are always correct! As the gasfitter you are still required to check the appliance you are installing. When OTR gas inspectors have checked burner pressures on several Rheem Stellar Hot Water Heaters during audits, the burner operating pressure has been measured as little as 0.8kPa. Rheem and SIT gas valve specifications and appliance data badge require the burner pressure to be set to 1kPa +/-5%.

If you have confirmed the inlet pressure to the appliance and SIT valve is 1.13kPa or above, and you get less than 1 kPa burner operating pressure then you will need to inform Rheem for warranty as the SIT gas valve is non-adjustable and may need replacment. Rheem will send a warranty service agent out to investigate. This should be noted on your eCoC as the appliance has not been commissioned fully as per the manufacturer’s instructions.

Part of your responsibility when installing any gas appliance is to commission the appliance to the manufacturer’s instructions. If you have established that the inlet pressure to the appliance is correct, but the outlet pressure is low adjust gas pressures via the gas appliance valve regulator as per manufacturer instructions and check the flame picture for anomalies. If you find the gas regulator is non-adjustable and the pressures do not meet specifications, you MUST contact the manufacture and explain your findings to preempt warranty service.

Non-compliant Hot Water Installations

What do the Hot Water installations pictured below have in common?

If you haven’t already guessed, they are all NON-COMPLIANT

The OTR receive numerous calls from Gas Fitters, Builders, and homeowners almost on a weekly basis because their gas meter install was refused, or the results of an audit have been met with loud protests.

In most cases installers or homeowners are ignorant on the requirements for installing or housing an external hot water heater under a covered area. Clause 6.9.4 allows placement of an external hot water heater under a covered area if it is open on at least 2 sides, (i.e. 50% of the total walled area). This is to ensure there is good cross flow ventilation to provide air for combustion, appliance cooling and allow the safe diffusion and venting of products of combustion.

To put it simply, if the location of a hot water heater install is non-compliant, you will be directed to move it. We have covered this repeatedly in past Regulation Roundup editions and annual Gas Roadshows, but the message just doesn’t seem to be getting through.

Meter knockbacksWith land mass decreasing in size and high density buildings bordering side boundaries there is a need to consult with the builder / developer and architect at planning stage prior to first fix to discuss if an external continuous flow gas hot water heater is the right option. In some cases, a flued internal model would be a better choice, but as usual economics and aesthetics seem to drive things. As a gas contractor you should pay special attention to water heater locations with respect to locations meeting clause 6.9.4.

Audit findingsThe common excuse, “Well the the last one was fitted there” doesn’t mean the installation was compliant, does it? We suggest you cover all the bases with the customer and explain that you have to relocate the appliance due to the location being non-compliant (this could be due to café blinds being subsequently installed for instance), have your standards handy so you can justify your decision if challenged.

The new AS/NZS 5601.2 – 2020 Gas installations for LP Gas installations in caravans and boats for non-propulsive purposes, was released late last year. This standard limits the size of

LP Gas cylinders on domestic caravans or boats to an individual maximum water capacity of 25 litres (nominally 10kg) and the maximum number of LP Gas cylinders that can be connected

to an installation on a domestic caravan or boat is capped at two. Ref Clause 3.1.2

For commercial applications like mobile kitchens, cylinder capacity can be greater however they must be stored, transported, and installed as per the AS/NZS 1596 Storage and Handling of LP Gas.

Cylinder Restrictions On Domestic Caravans and Boats

REGULATION ROUNDUP | 14

The control area around LP gas cylinders mounted on the draw bar of a caravan has changed. A new minimum clearance from sources of ignition for cylinders with a water capacity of 25 litres or less exists. See Figure 3.1.8(A). The new clearance requires a horizontal exclusion zone around the base of the cylinder of 1060mm, this is measured from the centre of the cylinder going outwards. The area directly below this exclusion zone radius down to the ground must also be free of ignition sources. There still needs to be a minimum 500mm clearance from ignition sources above the cylinder valves which extends out 500mm in a horizontal radius.

For exchange LP Gas cylinders with a greater water capacity of 25 litres still require a base radius exclusion zone around the base of the cylinder of 1.5m.

For clearances around cylinders to openings into a caravan are still the same, the new AS/NZS5601.2 has a new diagram Figure 3.1.8(D) shows shaded areas where openings like doors or vents are prohibited to be located. Ref Clause 3.1.8

One side is crimped, the other side isn’t.This fitting shown in the photograph contained gas for over 10 years without any reported issues. A minor disturbance of the gas pipe by unrelated work caused slight movement of the joint resulting in it leaking gas. The position of the vertical pipe above the joint was critical in that a few mm of movement 500 mm above was all it took to expose the leak.

You may well ask how can I prevent this from happening? Most crimp system manufacturers advise installers to mark each pressed joint with a texta so that it is clear that a joint has been crimped? Even then, do you visually check each joint afterwards in order verify they are crimped or do you rely on luck? Remember luck can also be bad (luck) if you don’t check your work properly, fortunately this was a lucky escape as it was outside, well ventilated and no fire or explosion occurred.

The gas fitter who installed this pipe and fitting was in such a rush, he was too busy to crimp the fitting, he also forgot to saddle the vertical pipe allowing the pipe to move and magnify the leak. The pipe could have fallen out of its fitting at any time which would of resulted in a 20 mm copper open end. If that occurred then maybe the installer would not be so lucky if the ensuing investigation had discovered that he was negligent and did not install or test the installation properly.

Insurance companies investigate most insurance claims and if the installer is found to be neglegent the insurance company will often seek commercial cost recovery. The last thing you want is to have to claim against your commercial liability insurance as your premiums may go up for a very very long time.

The purpose of the Standard is to prescribe the minimum requirements and responsibilities of all parties involved in dual reticulation infrastructure to ensure the safety and reliability of the water services provided to South Australian consumers.

The Standard was developed due to an increase in incidents in South Australia over recent years. The Office of the Technical Regulator (OTR) also identified that industry practice was inconsistent across various parties (i.e. developer, builder, plumber, water utilities). These issues coupled with the forecast for increased dual reticulation developments across the state supported the development of the Standard.

The Standard provides clarity on mandatory requirements related to the installation and connection of dual reticulation systems to properties and will enable the OTR to standardise industry practice to prevent cross connections. This Standard is in addition to requirements set out in the Water Services Association of Australia (WSAA) codes.

The Standard is not retrospective and will not apply to existing infrastructure. However, further work and repair on existing infrastructure is expected to comply with the Standard.

A 12-month transition period was in place to allow all water industry entities time to adapt to the new requirements. The transition period ended on 30 June 2021 and it is now expected that all new infrastructure will comply with the Standard.

The Standard and additional information, including FAQ’s, can be found at the following web page: https://www.sa.gov.au/topics/energy-and-environment/electrical-gas-and-plumbing-safety-and-technical-regulation/acts-regulations-and-standards/water-and-sewerage-acts,-regulations-and-standards

Trade wasteThe OTR would like to advise that we have published a new Plumbing Advisory note on solutions for the installation of plumbing pipework and equipment connected to Trade Waste pre-treatment systems. It is also important to contact SA Water to obtain authorisation prior to discharging trade waste into the sewer.

In areas where the sewerage infrastructure is not owned by SA Water, the property owner would need to contact the authority responsible for the infrastructure.

Limiting unauthorised discharges into infrastructure protects the environment and the integrity of the sewerage infrastructure.

Office of the Technical Regulator

Requirements exist which are specific to the connection of trade waste pre-treatment devices connected to the sanitary drainage system.

The Office of the Technical Regulator (OTR) regulate the installation of pipework connected to the inlet and outlet of any pre-treatment device, including the associated venting requirements.

The OTR require a hydraulic design to be submitted for all trade waste plumbing installations, the submission must be provided to the OTR 14 days prior to the installation. All trade waste plumbing installations must be booked in for auditing with the OTR.

All trade waste pre-treatment devices must connect to the sanitary drainage system via a disconnector gully.

Pre-treatment requirementsValid authorisation is required before discharging trade waste into the sewer.

An application must be submitted to SA Water for approval to discharge trade waste. SA Water will provide the applicant with the minimum trade waste pre-treatment requirements.

If the trade waste system is not connected to SA Water infrastructure, consult the relevant water industry entity for pre-treatment requirements.

Venting requirementsThe following venting requirements for trade waste apply:

• SA Water require a wind driven turbine cowl must be connected to the upstream end of the common discharge pipe connected to the pre-treatment device. Wind driven turbines must not be fitted on trade waste stacks that exceed 8 levels in height.

• The minimum size upstream vent connected to the common discharge pipework is DN 80. The vent should be installed between the last 2 fixtures.

• The upstream, tank and sealed gully vents associated with trade waste systems must be vented to atmosphere and not be interconnected to any other vent in accordance with AS/NZ 3500.2 clause 6.9.

• Air admittance valves (AAVs) can only be installed on trade waste branches and trap vents in accordance with AS/NZ 3500.2 clause 6.10.

• Chem vent AAVs can be installed in applications where chemicals or acid are being used (refer to the manufacturer’s specifications).

• Charcoal vents must not be used on trade waste installations.

Silt trapsSilt traps must be fit for purpose and constructed of approved materials.

The following fixtures/appliances may be connected to a silt trap:

• potato peelers

• hand basins

• preparation sinks

• kitchen sinks.

NOTE: Pot sinks must not connect to a silt trap. They must be connected individually to the trade waste drain.

The maximum length of a DN50 (or smaller) trapped waste pipe discharging to a silt trap is 6 m.

The maximum length of a DN65 (or larger) trapped waste pipe discharging to a silt trap is 10 m.

Plaster traps

Sinks must discharge untrapped to a plaster trap. Plaster traps must discharge to a sealed gully.

Trade waste plumbing requirementsPlumbing Advisory Note – Revised June 2021

Sinks must discharge untrapped to a plaster trap. The outlet of the plaster trap shall have a DN50 trap that discharges to a sealed gully.

REGULATION ROUNDUP | 20

Trade waste pipework, equipment and materialsThe disconnector gully on the outlet of the trade waste arrestor must not have any other waste discharge. It may dilute or alter the quality of the discharge.

All grease arrestor covers cast in concrete paths must be at least 50 mm above the surrounding finished ground level to prevent the ingress of surface water.

When selecting the material to be used for connection, it is important to consider:

• hot water discharges such as those from:

– pasta cookers

– woks

– combi ovens

– dishwashers

• the temperature of the waste water discharges

• the risk of corrosion and degradation.

Note: Glass washers are not required to be connected to a pre-treatment device.

Food waste disposal unitsThe installation of food waste disposal units is assessed by SA Water on a case by case basis. Installation is only approved under special circumstances or when alternative solutions don’t exist.

Pumping trade waste discharges to a grease arrestorWhen pumping trade waste discharges to a grease arrestor, the following requirements apply:

• The pump station must be fit for purpose and sized adequately.

• Vents from pumping stations must be a minimum size of DN 50 and must be positioned a minimum of 100 mm above the waste inlet.

• Pumps must be suitable for the application for both temperature and nature of the discharge, for example, fat, solids etc.

• Waste pumped to a grease arrestor must enter through a 45° junction.

• The minimum length of the drain gravitating to an arrestor is 500 mm.

• An inspection opening must be installed on the trade waste drain inlet to the arrestor for sampling purposes.

Connection of fixtures in trade waste installationsThe following table lists typical fixtures in a trade waste installation. Specific requirements included in a SA Water Trade Waste Permit may take precedence over those in the table.

[ The Water Industry Act – Plumbing standard 2020 revision ]The Technical Regulator ‘s Plumbing Standard has been revised. The revision was Gazetted on 3rd December 2020. The amended standard clearly details the requirement for plumbers to book audits with the OTR. Please click here to view the revised standard:

Interactive Water Features – Storage tanksRecent field audits of Interactive Water Features (IWF) with hand play pumps have shown there is still some confusion around the installation of small capacity storage tanks.

These storage tanks on IWF sites are usually used to contain low volume of drinking water to enable the function of hand operated suction pumps and alike.

The storage tanks for IWF’s must be above ground.

Some older information on the location and the acceptance of partially buried storage tanks was causing confusion, so for further clarification tanks must be above ground.

Other important details to note on the installation of IWF’s.

• The design of IWF plumbing and equipment installation must be submitted to the OTR Plumbing section.

• All tanks shall be installed on bases, plinths or supports design to support the weight of the tanks.

• All tanks should have a sealed cover to prevent the entry of dust, roof water, surface water, ground water and bird or animal life.

• All tanks shall be accessible for inspection, repairs, maintenance, and replacement.

• RPZD where required are to be installed 300mm above the surrounding ground level for correct operation.

• Venting backflow devices may require drainage provisions.
