What is a lighting circuit?

A lighting circuit is specifically designed for lighting fixtures, which includes light bulbs, lamps, and other related equipment. This type of circuit is configured to handle the specific electrical load requirements of lighting devices, ensuring they operate efficiently and safely.

In a lighting circuit, the wiring, circuit breakers, and other components, such as switches, are selected based on the needs of the lighting fixtures that will be connected. This ensures adequate power is supplied and allows for the control of multiple light sources from a single switch or set of switches.

The focus on lighting fixtures distinguishes this circuit type from others that may be used for different purposes, such as heating appliances, power distribution, or general outlet connections. Each of those alternatives would have different specifications and requirements based on their intended use, thus reinforcing the specificity of a lighting circuit.
