Abstract
A plastic load center box economically provided by duplicate molded end sections joined by an intermediate section of uniform cross-section which is readily provided in selected lengths in either molded or extruded form. End walls receive metal inserts electrically interconnected to provide grounding when attached to grounded conduit, or plastic inserts where the load center application does not require grounded conduit. Molded end sections have formed knockouts and wire clamping tabs.
