The wiring from a light to a switch box is known as what?

The wiring from a light to a switch box is referred to as a switch loop. This term specifically describes the electrical configuration that allows a light fixture to be controlled by a switch. In a switch loop, the power source is typically connected to the switch first, and then a wire runs from the switch to the light fixture. This setup enables the switch to control the flow of electricity to the light, allowing it to be turned on or off.

Understanding this terminology is crucial for anyone working with electrical systems, as it clearly defines the role and function of the wiring involved in controlling lighting. It is important to note that the light loop and power loop do not accurately represent the concept, as they focus on different aspects of electrical wiring, and a control loop typically refers to a different type of circuit governing automated systems or devices, rather than directly controlling a light fixture.
