Eaton’s Cutler-Hammer Type BR Loadcenters (also known as a breaker box) include a one-piece aluminum or copper bus. This absence of bolted connections virtually eliminates the chance of hot spots or faults, ensuing a longer product life. Our main lug panels, also known as sub-panels, are ideal for garages, home additions, and workshops. A variety of knockouts allows for more wiring configurations, while predrilled mounting holes provide easy installation of additional ground bars, if desired. Type BR Loadcenters have a 10-year warranty and accept Cutler-Hammer Type BR (1-inch) breakers.
