Installed wiring devices, wall switches, and receptacles are used to install new electrical systems in new construction projects or to upgrade or repair existing systems in older buildings. Wall plates install over the front of electrical enclosures to protect the electrical devices and wiring inside the enclosures. Locking receptacles, pin-and-sleeve receptacles, and straight-blade receptacles accept compatible plugs to allow equipment to be connected to an electrical supply. Wall switches turn lights, fans, and equipment on and off. Wiring combination devices contain more than one electrical device, such as a switch and an outlet, two switches, or two outlets.
