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. This panel is a main lug panel which is used as sub-panel to add circuits to an existing main breaker panel. Sub panels are often used in a garage, home addition, barn or storage shed and/or workshop. The branch breakers protect the wires leading to individual electrical loads such as fixtures and outlets. The Br612L125Sdp is a 125 Amp main lug with 6-spaces and 12-circuits.
