What is the difference between a device, a fixture, and an appliance?
These terms are sometimes used interchangeably. A fixture usually refers to a light that is permanently installed in a ceiling or a wall. An appliance refers to almost any electrically powered machine or apparatus that uses electricity. A device (e.g., switch, breaker, receptacle) is used to allow or interrupt the flow of current through the circuit to fixtures, appliances, or lamps.
