Product Overview
Specially designed for easy installation, Eaton's BR 1-inch load centers house the branch circuit breakers and the wiring required to distribute power to individual circuits. They serve as main breaker for service entrances or as main lug when adding circuits to existing service. The main breaker protects the entire panel and can be used as a service disconnect. The branch breakers protect the wires leading to individual electrical loads such as fixtures and outlets.
