Specially designed for easy installation, Eaton's BR load centers house the branch circuit breakers and the wiring required to distribute power to individual circuits. The panels serve as main breaker for service entrances. The main breaker protects the main 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. The BR816B200RF is a 200 Amp outdoor main breaker with 8 spaces and 16 circuits.
