In electrical terms, what does "lighting load" refer to?

"Lighting load" refers specifically to the total current needed for lighting devices. In electrical systems, the lighting load is an important consideration for determining how much power is required to adequately supply lighting fixtures, ensuring that they function properly without overloading the circuit. The calculation typically involves measuring the rated wattage of each lighting fixture and converting that into current, usually measured in amps, using the voltage of the system.

This concept is crucial in electrical design and planning because it helps in sizing circuits and selecting appropriate circuit breakers. By knowing the total current for lighting, electricians can ensure that the infrastructure can handle the load effectively, which promotes safety and efficiency in electrical systems.
