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.

Power distribution panelboard

A molded insulating housing is received in a slot in a rear panel of a removable control unit to extend on front and rear sides of the panel. Solid bus conductors mounted in the housing have their opposite ends disposed within front and rear openings in the housing. Plug-in connector clips are affixed to the solid bus conductors adjacent the rear openings for plug-in connection with control center vertical bus bars. The solid bus conductors are afforded limited transverse sliding movement within the housing relative to the vertical bus bars for self-alignment of the plug-in connector clips with the bus bars. Bolted connection of the solid bus conductors to control apparatus is effected at the front of the control unit using a solid preformed connector strap.
