ABSTRACT:
An enclosure for drawout circuit interrupters having instrumentation and control wiring includes a housing having circuit interrupter recesses; wiring tray recesses; wiring trays each of which hold the wiring for one of the circuit interrupters; drawout mechanisms for removing the trays from the tray recesses; and brackets for hanging the trays from the enclosure. The trays may have a molded plastic front panel. The trays may also have internal lances or holes for securing the wiring thereto, two rear holes for routing the wiring therethrough, and a bottom side having holes for mounting rails for securing terminal blocks or fuse blocks thereto. The rear holes may hold peripheral plastic conduits for protecting the wiring. The front panel may have recess pockets for holding a descriptive nameplate, and center punches to facilitate mounting instrumentation or control devices. The drawout mechanisms may have a rectangular guide bar beneath the trays. Each tray may have a corresponding guide mechanism which rests on the guide bar. The guide mechanism may have two arms each of which abut a side of the corresponding guide bar. The drawout mechanisms may further have H-shaped slide bars attached to the sides of the trays and L-shaped brackets attached to the housing within the tray recesses. Each of the L-shaped brackets may have a C-shaped channel for guiding one of the slide bars. The drawout mechanisms may also have blocking tabs for partially blocking a drawout movement of the trays from the tray recesses.
