Abstract

A molded plastic load center enclosure allows the circuit breakers contained therein to be compactly aligned on one side of the enclosure. Depressions formed within the bottom of the interior surface of the enclosure produce bosses extending from the exterior surface thereof, which provide a cooling air circulatory space between the enclosure and a support wall. Metal disks inserted within the depressions provide increased thermal capacity to the enclosure interior while allowing the use of explosive charge-driven nails to attach the enclosure to the support wall without damaging the plastic material.
