Specially designed for easy installation, Eaton's CH 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 CH2L70SP is a 70 Amp main lug with 2 spaces and 2 circuits.
