Abstract
Abstract A non-metallic panelboard comprises an insulative, molded plastic enclosure consisting of a housing having integrally formed back and sidewalls and a separable cover. The housing is adapted for both surface mounting to a finished wall and mounting to a wall stud in recessed relation to the finished wall. The housing is also adapted to accept two cover forms; one in the situation where the housing is surface mounted and the other in the situation where the housing is recessed mounted.
