ABSTRACT:
Plug-on enclosed fusible switches, enclosed lug devices and non-enclosed molded case circuit breakers are attached to a panelboard in a single or side-by-side double row. Spring biased latches retain the devices to the panelboard. Locating notches on the panelboard locate the devices at incremental spacing to provide a variable, compact arrangement for the devices. Filler plates and end structures on the devices cooperate with a cover for the panelboard to provide an integral dead front. The panelboard is particularly adapted for field assembly, including attachment of a main feed device which effects a plug-on feed in either a single or electrically parallel double panel arrangement.
