Abstract: A fitting, adapted to fit in a hole formed in a fire-rated floor, to enable activated wires to be connected thereto and therethrough for activation as an outlet. The fitting includes a receptacle which includes a plurality of bus bars adapted to connect and isolate current inputs to enable the fitting to accommodate multiple power plugs for multiple electronic devices. The receptacle further includes plug blade retention contacts adapted to firmly grip, retain, and provide positive contact and connection between plug blades and receptacle outlets. It further includes grounding contacts and wires adapted to effectively ground electronic equipment. The fitting further includes a service head adapted to extend substantially flush with the top of a carpet, to prevent unsafe obstruction of the carpet, and sliding plates adapted to automatically and positively cover receptacle outlets to prevent electrical shock.

Abstract: A quadruplex receptacle where all four receptacles can be connected in common to a single electrical cable or by severing the connecting links on its line bus it can be divided into two duplex receptacles each fed by a single cable. A feed-through arrangement can be used with either arrangement of the line bus. The neutral bus surrounds the line bus, both supported and electrically insulated from one another by a series of tabs and columns in the cavity within a housing. A ground bus extending into the cavity from a rear cover provides an isolated ground. Mounting apertures in the housing and cover permit mounting to a support surface, to a standard gang gem outlet box, or by means of an adapter plate to a number of mounting devices. A box can be placed about the cover to provide a portable device.
