Answer:Wiring devices are current-carrying electrical or electronic products that serve primarily as a connection or control point for electrical circuits within a range of 0–400 amperes, 0–600 volts (AC and DC), and AC/DC (660 watts, 1,000 volts AC fluorescent) as well as certain non-current-carrying wiring devices and supplies.
Wiring devices include:
Convenience plugs and power outlets (plugs and receptacles)
Connector bodies and flanged outlets
Cover plates
General-use switches and dimmers
Lampholders (incandescent, fluorescent, cold cathode, neon, quartz lamps, and others)
Lighting control devices
Motion sensing and timer switches
Receptacles
Switch, outlet, FM/TV, blank, and telephone plates
Undercarpet premise wiring systems
Products include receptacle-type arc-fault circuit interrupters (AFCIs), protection devices that can detect an unintended electrical arc and disconnect the power before the arc starts a fire. AFCI technology in residential and commercial buildings is an important electrical safety device.
