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. It further includes intumescent rings and phenolic insulating rings adapted to seal the floor hole and wires extending through the fitting, to enable the fire rating of the floor to be substantially the same with or without the hole and fitting therein.
