This document provides descriptions and images of common electrical wiring hardware used in residential and commercial construction. It identifies various boxes, cables, conduits, connectors, covers, lampholders, receptacles, switches, service equipment, and other miscellaneous hardware. Examples include octagon boxes, NM cable, rigid metallic conduit, wire nuts, grounding clips, duplex receptacles, single-pole toggle switches, wall plates, and cable clamps. The images were photographed by Cindy Lamb-Basham and Dave Wilson at the University of Illinois to illustrate electrical hardware components.
