In electrical systems, what does the term "load" refer to?

The term "load" in electrical systems specifically refers to the amount of electrical power consumed by devices or appliances. Loads can include anything from lighting fixtures to large industrial machines that use electricity to perform work. Understanding the load is crucial because it directly affects the design and capacity of electrical systems, including the sizing of conductors and protection devices.

When evaluating a circuit, knowing the load allows for proper calculation and ensures that the circuit can handle the power demands without resulting in overheating or failure. Managing loads effectively is crucial for safety and efficiency in electrical installations.
