E3-2 Low-Voltage Switchgear and SwitchboardsLow-Voltage Distribution Switchboards

General Description

Application Considerations and Definitions

Pow-R-Line designates a family of distribu-tion switchboards incorporating new design concepts that fit the ever-increasing need for applications on high short-circuit systems, while retaining maximum standardization, safety and convenience throughout the line.

Front Accessibility

Front accessibility switchboards align at the rear, enabling them to be placed against a wall (Cutler-Hammer Type Pow-R-Line C front accessible). If the main section is deeper than others, due to physical size of the main device, the necessary off-set in line up will occur in front, and the main section will be accessible from the side as well as from the front. Cutler-Hammer also offers front ac-cessible switchboards that align at the front and rear.

Rear Accessibility

Rear accessible switchboards align at the front and the rear. Bus maintenance and cable entry and exit require rear access. There are two types of rear accessible switch-boards. Both types utilize the same incoming utility and/or main structures. The first type utilizes group mounted feeder devices with panel construction (Cutler-Hammer Type Pow-R-Line C rear accessible). The second type utilizes individually compartmentalized feeder devices with load side insulated bus bar extensions (Cutler-Hammer Type Pow-R-Line

i

).

Standard Switchboard Height

Standard Pow-R-Line switchboard height is 90 inches.

Group Mounting

Group mounted circuit protective devices are an assembly of units mounted on a panel-board type base (panelboard construction). Units may be molded case breakers, or FDPW fusible switches. Circuit protective devices are accessible from the front.

A main molded case breaker or main FDPW fusible switch, within the sizes listed for pan-elboard design, can be included in the panel mounted assembly in lieu of a separate, individually mounted unit.

Space Only for Future Devices Group Mounted Construction

Where space only for future circuit protective devices is required, the proper space and a blank filler plate will be supplied. Connections and mounting hardware are not included.

Provision for Future Devices

Where provisions for future circuit protective devices are required, space for the device, corresponding vertical bus, device connec-tors and the necessary mounting hardware will be supplied.

Bus Bar System

Standard bus in the switchboards is tin-plated aluminum. Copper and silver-plated copper are also available.

Main bus and sub-main busses meet UL and NEMA standards for temperature rise on all Pow-R-Line switchboards. Special bus densities are available.

Overcurrent Devices

To properly select and size overcurrent devices for use in a switchboard, the allowable tem-perature rise must be taken into account as to its effect on the tripping characteristics of the devices in question.

Accordingly, Article 220-4(a) of the NEC requires overcurrent devices to be rated not less than 125% of the continuous load they are protecting. To comply with this, an 80% derating factor must be used with all overcur-rent devices such as molded case breakers and FDPW fusible switches unless they are tested and approved for application at 100% of the rating.

Short Circuit Rating

Standard bus and connectors on all switch-boards are rated for use on Systems capable of producing up to 65,000 amperes rms sym-metrical short circuit current at the incoming terminals.

Increased bus short circuit ratings equal to that of connected switchboard devices, up to 200,000 amperes rms symmetrical, are avail-able in most Pow-R-Line switchboards when approved main devices are installed. Contact Cutler-Hammer for more information. UL labeled switchboard sections are marked with their applicable short circuit rating.

Provision for Busway Entrance and Exit

Busway connections to switchboard sections include cutout and drilling in the top of the switchboard with riser connections from the switchboard device or bus, up to the point where the bus duct enters the switchboard. No connections are furnished external to the switchboard.

In all transactions involving busway attached to switchboards, it is essential that information regarding orientation of the busway with respect to the front of the switchboard be supplied to the coordinatingassembly plant.

On Pow-R-Line switchboards, solid bus bar is used to connect the bus duct to the individu-ally mounted main device, main or sub-main switchboard bus, or vertical main bus of panel mounted circuit protective device panels.

Busway fed by group mounted branch devices are cable connected.

Aluminum riser connections are standard. Copper- or silver-plated copper is available as a modification.

Transitions

Transition structures are required for con-necting switchboards to the secondary of power center transformer (dry or fluid filled), motor control centers, and for other special switchboard configurations such as “L” or “U” shaped lineups. In some application, an extra structure complete with connections is required; in others, where switchboard depth and space permit, only the connection conductors are required. (Refer to factory for these applications.)

Auxiliary Structures

These are normally mounted adjacent to service structures or distribution structures and used where incoming service or feeder conductors require additional space or facilities not included in the standard switchboard, such as:

1. Mounted adjacent to a top connected service structure and used as a cable pull structure where service conductors are brought in underground. Auxiliary struc-tures are the same depth and height as the service structure, and are wide enough to accommodate the incoming cables.

2. Mounted adjacent to a service structure and used as a bus transition compart-ment for running riser bus from the load-side of the service structure up to top outgoing bus duct connection when distribution structures are not required. Auxiliary structures are the same depth and height as service structures.

In addition to the above applications, auxiliary structures may be mounted adjacent to a dis-tribution structure and used as a structure for lighting panel or other device which may be cable-connected to a branch circuit device in the distribution structure. Dimensions are compatible with arrangements required.

Switchboards Used as Service Equipment

Service equipment is the electrical equip-ment that constitutes the main control and means of power cutoff the electric service (normally power company supply) brought into the building.

Where switchboards are to be used as service equipment, certain NEC and UL requirements apply that necessitate modifications not normally supplied in switchboards.

The following is a summary of the require-ments which are pertinent to the application of a switchboard for service equipment:

c. A switchboard with main lugs only (no main disconnect) must be designed so that all circuits in the switchboard can be disconnected from the supply source by the operation of no more than six operating handles (breaker or switch).

E3-43Low-Voltage Switchgear and SwitchboardsLow-Voltage Distribution SwitchboardsType 3 General Description – Rear Accessible, Compartmentalized Feeder Devices

Pow-R-Line i Switchboards can help to provide for future distribution system requirements by includ-ing empty compartments for branch circuit break-ers and fusible devices. (Circuit breaker provisions shown.)

Ground fault test panels can be mounted in com-partments with the circuit breakers for convenience and space savings.

A standard feature of the Magnum DS Breaker, a main device, is the third generation Digitrip RMS Trip Unit that provides circuit protection, informa-tion and testing functions, and true RMS sensing.

Pow-R-Line i SwitchboardsGreater Flexibility and IncreasedSafety FeaturesPow-R-Line i Switchboards are engineered in a new compartmentalized design for applica-tions where a greater degree of safety is required. A wide variety of configurations is possible including utility metering, customer metering, main devices, branch devices, accessories, and enclosures.

Significant safety features include:● Individual compartments for branch

devices — glass polyester for circuit breakers and steel for fusible switches. These compartments help eliminate pos-sible contact with the main bus and reduce fault propagation.

● Three-section construction with each section barriered from the other.– Device Section. Each device is

mounted in its own compartment.– Bus Bar Section. Contains both hori-

zontal and vertical busses.– Rear Cable Compartment. Completely

isolated from the bus bars.● Insulated copper runback. Power is taken

from the protective device by the insulated copper runback through a standard full height glass polyester barrier to the rear cable compartment. This design virtually eliminates the possibility of accidental contact with the main busses during in-stallation or maintenance.

A Wide Selection of Main and Branch DevicesMain devices are available from 400 to 4000 amperes and can include Molded Case Circuit Breakers, Magnum DS and DS Breakers, FDPW fusible switches or bolted pressure switches. Main busses are rated up to 4000 amperes.

Branch circuit breakers range from 150 to 1200 ampere frames. When Series C Circuit Breakers are used, higher ratings and increased series ratings will be achieved. Branch fusible switches are available from 100 to 1200 ampere frames.

Short circuit ratings up to 200,000 amperes are UL listed and the bus bar system may be braced from a standard 65,000 amperes up to a maximum 100,000 amperes.

Pow-R-Line i Switchboards are UL listed and meet all applicable requirements of NEMA and NEC. They are rear accessible and front and rear aligned.

IMPACC/PowerNetIntegrated Monitoring Protection and Control Communications System An IMPACC/PowerNet System expands the capabilities of distribution and control assem-blies by tying together multiple devices in electrical distribution systems. From a central location (on-site or off-site), an operator uses a personal computer (master control unit) to monitor, control, and communicate with com-patible devices on a distribution system. These microprocessor-based devices, designed and built by Cutler-Hammer, per-form monitoring, protection, and control functions.

Space Saving Ground Fault Test PanelsPow-R Line i Switchboards can accommodate either integral or zero sequence types of ground fault protection. Depending on the specific application, a test panel can be mounted in the circuit breaker compartment which may eliminate the need for an auxiliary structure.

Provisions for FutureFuture expansion provisions include line side connectors, load side runbacks, terminals, and glass polyester compartments and covers (for circuit breakers).

Cutler-Hammer’s Integrated Design Provides Lowest System Let-Through Voltage at the Bus Bar

● The CPS stated let-through voltage is a true indication of the suppressor’s performance.

● Other TVSS products are measured at the TVSS module or the suppressor terminal, not at the bus bar. The distance between module or suppressor terminals and switchboard bus bar can be up to 14 inches or more. The impedance associated with this lead length can significantly increase the transient let-through voltage.

The TVSS Tri-MonitorE is the most reli-able and comprehensive diagnostic sys-tem available in the industry. This design incorporates three levels of detection:

1. Coordinated monitoring of 200 kAIC internal fuses.

2. Infrared sensor monitors individual MOVs including N-G and identifies component damage such as open MOV failure.

3. Thermal alarm detects overheating due to thermal run away.

Any problems detected by the TSS MonitorE will activate the flashing trouble light, audible alarm and Form C contacts.
