Application Information
Loadcenter Construction
Cutler-Hammer Type BR loadcenters have standard tin-plated aluminum bus with a limited availability of copper bus. The sum of the handle ratings connected to any stab is limited to 150 amperes maximum on the 100 and 125 ampere loadcenters, and 200 amperes on load-centers with 150 ampere or higher main bus. NEMA Type 1 boxes or enclosures are manufactured from G60 16-gauge galvanized steel. Raintight boxes are manufactured from G60 16-gauge galva-nized steel, then finished using an elec-trostatic powder coat, baked urethane paint process.
UL Listings
All Cutler-Hammer Type BR loadcenters are listed under UL file E52977 except the 2-8 circuit loadcenters, up through and including 125 amperes, which are listed under UL file E8741.
Neutrals
Cutler-Hammer Type BR loadcenters feature two types of neutrals:Split Neutrals – Single-phase load-centers 12 circuits and above feature a twin neutral (mounted on both sides of the interior assembly) with a cross bus connecting them unless otherwise noted. The neutral is bondable in the field by means of a bonding strap that is supplied with each loadcenter. The cross bus is not removable for separate ground and neutral bars. For sub-feed applications, a separate ground bar must be used. In a service entrance applica-tion, where the neutral is bonded, unused neutral connections may be used for equipment ground conductors.Single Neutral – Single phase 2-8 circuit, three-phase and commercial loadcenters are supplied with a single insulated/bondable neutral. The three-phase load-center neutral is movable to the other side if desired. The neutral is bondable in the field by means of a bonding strap that is supplied with each loadcenter. For sub-feed applications, a separate ground bar must be used. In a service entrance application, where the neutral is bonded, unused neutral connections may be used for equipment ground protectors.
Grounds
Separate ground bars are supplied on those loadcenters having a “G” in the catalog number. For service entrance panels not having a separate ground bar, the extra neutral terminals may be used for equipment ground conductors. When using the loadcenter as a sub-feed, the bonding strap should not be attached, and a separate ground bar must be installed.
Neutral and Ground Terminals
The standard terminals on grounds and neutrals are rated to accept (3) – #14-#10 Cu/Al or (1) – #14-4. For larger cables, add-on neutral lugs may be ordered from the accessories on page C-16.
Bottom Fed Loadcenters
Where power cable is brought into the loadcenter from below the panel, main lug panels, and single-phase, 225 ampere and below loadcenters can be rotated 180 degrees to allow straight-in wiring of power cables to the main ter-minals. Because the main circuit breaker handle operates horizontally, the orien-tation of the main circuit breaker handle is consistent with the requirements of NEC Article 240-81.
Gutter Splicing
Loadcenters are not UL listed as wiring troughs. Therefore, gutter splicing of riser cables to tap off to the main device is not permitted.
Fire Rating
Due to the numerous openings in both loadcenter boxes and trims, they should not be mounted in firewalls. There is no approved method for sealing the enclo-sures for this application.
Date Code
The date of manufacture of each load-center is printed on the outside of the carton as well as inside the loadcenter. On the carton, the date code is printed on the end carton label. In the load-center, the date code is located on the small white label located on the right side wall (with the main device on top).
➀ See Cutler-Hammer Publication Number SA-365 for complete details.
Application Notes and Extended Warranty Highlights
The date code is in the following format:F # # # = . The “F” is the numeric code for the Lincoln, IL plant, and the three numbers are the year and week of manu-facture e.g. 623. The “=” sign at the end signifies the decade of the 1990s. There-fore, the date code F623= would indicate that the product was manufactured in the 23rd week of 1996. The 1980s are represented by a “+” sign at the end of the code.
Surge Protectors
The BRSURGE Surge Protector has indi-cating lights that indicate when the units should be replaced. The CHSA01 and CHSA03 Surge Protectors internally short, causing the circuit breaker feeding the surge protector to trip. All but the BRSURGE Surge Protector should be wired to the load side of 15 or 20 ampere feeder circuit breakers mounted adjacent to the main incoming device.
The CHSPCH Clipper Home Surge Protector is an externally mounted TVSS unit that provides industrial level surge protection in a residential design.
Extended Residential Warranty Highlights ➀
■ Five-year branch breaker warranty.■ Five-year loadcenter warranty.■ Both the loadcenter and branch circuit
breaker warranties are extended to 10 years if a functioning surge protector is installed in the loadcenter.

Surge Protector
BRSURGE – For use on single-phase, 120/240V AC systems. This easily plugs into a single-phase Type BR loadcenter and occupies two 1-inch (25.4 mm) pole spaces similar to a 2-pole Type BR breaker. When plugged into the first two stabs at the top of the loadcenter just below the main breaker or main lug, it provides surge protection for the entire loadcenter. If internal components are damaged, the BRSURGE LED visual indi-cators will signal the need for replace-ment. This device is suitable for service entry locations installed in accordance with NEC Article 280. The BRSURGE is ideal for protecting sensitive appliances and electronics, such as refrigerators, microwave ovens, and home computers.
CHSA01 – For use on single-phase, 120/240V AC systems. This surge protector can be easily installed in the enclosure of indoor or outdoor loadcenters by using the 1/2-inch (12.7 mm) threaded nipple. It is ideal for protecting outdoor lighting, garages, sump and irrigation pumps, etc.
Surge Protector
CHSA03 – For use on three-phase, 600V AC systems. This surge protector is installed in the enclosure of indoor and outdoor loadcenters by using the 1/2-inch (12.7 mm) threaded nipple. It provides protection for commercial electrical ser-vices especially those using electric motors.

Ground Fault Application Notes
Single-pole GFCBs are designed for use in 2-wire, 120V AC circuits. Figure 1 shows a typical wiring configuration.
Two-pole GFCBs are designed for use in 3-wire, 120/240V AC circuits, 120V AC multi-wire circuits employing common, neutral and 2-wire, 240V AC circuits obtained from a 120/240V AC source.
Figures 2 and 3 illustrate typical wiring config-urations for a 120/240V AC multiwire circuits.
Figure 4 depicts a 240V AC, 2-wire circuit. Note the “panel neutral” conductor connects to the neutral bar, even though the neutral is not included in the load circuit. This connection is necessary to supply a 120V AC power source to the ground fault sensing circuit.
The figures are shown with a 120/240V AC, single-phase, 3-wire power source, but are also applicable to a 120/208V AC, 3-phase, 4-wire power supply. For all figures the electrical opera-tion of the GFCB is not affected by the equip-ment ground.
