Your Responsibilities

• You have the responsibility for your own safety

• You have the responsibility not to compromise the safety of Northern Powergrid staff or members of the public.

• Site specific risk assessments MUST be carried out in line with your own company procedures.

• Necessary testing shall be carried out prior to undertaking work and on completion of work e.g. polarity testing, supply, phase rotation (if required)

Reporting of Defects, Incidents and Dangerous Occurrences • Any equipment owned by Northern Powergrid found to be defective, such as to

present the possibility of danger or any part of the site or situations which are, or which might reasonably be, believed may become hazardous should be reported immediately by the Meter Operative. The points of contact and telephone numbers are given in Appendix 1 of the ‘Information for Meter Operators’ document on the Northern Powergrid website (and on the following slide) .

• A list of defects categories on service termination equipment for which the Meter Operator should make their operatives aware is provided in the MOCOPA Guidance for Service Termination Issue Reporting document. Category A defects shall be reported by telephone to Northern Powergrid. All other categories of defects/information shall be reported via the relevant data flows.

• Where an electrical incident has occurred at a Northern Powergrid service termination, it shall be immediately reported to Northern Powergrid on the emergency numbers detailed on the following slide.

Incidents

For reporting of service termination equipment issues that require urgent attention (category A issues) • Northeast 0800 917 9870 option 1 • Yorkshire 0800 917 9870 option 2

In the event of an incident / accident on site use the emergency contact number shown below.

• Northern Powergrid Northeast 0800 668877 • Northern Powergrid Yorkshire 0800 375675 • And your supervisor

Authorisation

• Each individual meter operative MUST be authorised by Northern Powergrid and hold a valid authorisation code certificate for the appropriate code BEFORE carrying out any metering work within the Northern Powergrid distribution network.

• Authorisations usually last for 3 years after which re-authorisation must be sought. Where breaches in operational practice are identified Northern Powergrid reserve the right to suspend or remove an individual’s authorisation.

• The meter operator is required to undertake an annual review of each individual’s system authority codes to ensure that the duties and activities performed within the review period are commensurate with the assigned authorisation/competence.

• The meter operator shall carry out regular audits on its operatives to ensure they are compliant with the requirements of their Northern Powergrid authorisation. The audit findings shall be made available to Northern Powergrid to review if requested.

• In the event that the authorised person has not performed the responsibilities for which he has gained the authorisation within the review period, Northern Powergrid may withdraw authorisation until additional test/assessment is undertaken in order to reinstate the authorisation level.

Authorisation Codes

Code Operation on LV Service Equipment

O1 LV switching and fuse operation on all LV service equipment

O1.1 Public lighting installations and street furniture

O1.2 Single phase installations

O1.3 Single phase of a multiphase supply

O1.4 Multi phase installations

O1.5 ISU installations with exposed LV

7

Authorisation Codes

O1.2 Single-phase installations • For operations on domestic and commercial single phase installations on cut-outs rated up to

100 Amps. O1.3 Single phase of a multi-phase supply • For the removal of one fuse from a multi-way cut-out or distribution board. Intended mainly for

meter operatives who only require to replace a single-phase meter. Operatives issued with this code will normally also receive code O1.2.

O1.4 Multi-phase installations • For operations on multi-phase cut-outs up to and including 500 Amps but excluding industrial

service units (ISUs). Operatives issued with this code will normally also receive codes O1.2 and O1.3.

O1.5 ISU installations with exposed LV • For operations on industrial service units (ISU) and multi-way fuse boards with exposed live bus-

bars. Operatives issued with this code will normally also receive codes O1.2, O1.3 and O1.4.

Guidance on Solar (PV) Panel installations • A Solar (PV) Panel installation must have an isolation facility. There is usually an

isolation switch in the area adjacent to the connection with the solar panels (within the loft space of the property) and one at the customers Distribution Board.

• Prior to commencing work, you must ensure that you achieve effective isolation to ensure that the service termination cannot be made live while undertaking work.

• You should see signing and labelling on any circuitry associated with a micro generation installation at a customers property.

• The following label is typical of the ones used to notify you that an independent electrical generation source is connected.

• Cut outs and codes required

NPG Authorisation O1.2 Single Phase Installations Code Required Restrictions Meter replacement and cut-out tails may be changed. Where exposed live

terminal exist then they shall be shrouded to replace the cut out tails

NPG Authorisation O1.2 Single Phase Installations Code Required Restrictions Meter replacement and cut-out tails may be changed. Where exposed live

terminal exist then they shall be shrouded to replace the cut out tails.

NPG Authorisation O1.2 Single Phase Installations Code Required O1.3 Single phase of a multi-phase Installation O1.4 Multi Phase Installation Restrictions Meter replacement and cut-out tails may be changed. Where exposed live

terminal exist then they shall be shrouded to replace the cut out tails.

10

Cut outs and codes required

NPG Authorisation O1.2 Single Phase Installations Code Required Restrictions If paxelin phase cover needs to be removed then the riser requires isolating under code O1.4 or O1.5

NPG Authorisation O1.3 Single phase of a multi-phase Installation Code Required O1.4 Multi Phase Installation Restrictions Dependant on whether it is a single phase or 3 phase the above codes are applicable

NPG Authorisation O1.3 Single phase of a multi-phase Installation Code Required O1.4 Multi Phase Installation Restrictions If the incoming terminals are suitably shrouded then the above codes apply If the incoming terminals are exposed in any way then code O1.5 is required

11

Cut outs and codes required

NPG Authorisation O1.3 Single phase of a multi-phase Installation Code Required O1.4 Multi Phase Installation Restrictions Following a risk assessment and no exposes busbars are identified then the tails can

be passed behind the busbars.If meter tails have to be passed behind exposed busbars, then an outage is required with Northern Powergrid removing the main distribution system incoming fuses

NPG Authorisation O1.3 Single phase of a multi-phase Installation Code Required O1.4 Multi Phase Installations Restrictions If meter tails have to be passed behind exposed busbars, then an outage is required

with Northern Powergrid removing the main distribution system incoming fuses

NPG Authorisation O1.5 Industrial Service Unit (ISU) Code Required Restrictions

12

Cut outs and codes required

NPG Authorisation O1.3 Single phase of a multi-phase installation Code Required O1.4 Multi-phase installation Restrictions Single phase and 3 phase meter replacement only, if meter tails require changing Then the LV board shall be isolated as this will be required as phase barriers will

require removing exposing live Busbars.

NPG Authorisation O1.5 Industrial Service Unit (ISU) Code Required Restrictions Live incoming terminals cannot be shrouded

NPG Authorisation O1.2 Single Phase Installations Code Required Restrictions Metal clad cut-out with strong possibility of asbestos content, suitably trained staff Could replace meter in an emergency but not the meter tails. Where the cut out

requires changing, then this shall be completed following the MOCOPA service termination issues reporting guide.
