Which type of branch circuit supplies only one utilization equipment?

The type of branch circuit that supplies only one utilization equipment is known as a Branch Circuit, Individual. This term is specifically defined in the National Electrical Code to indicate circuits that are designated to supply a single piece of equipment, which means it is dedicated to a particular load. This is important for ensuring that the equipment operates effectively without the risk of overload that could occur if the circuit were shared with other devices.

In contrast, a Branch Circuit, Appliance typically supplies one appliance but may not be categorized as an individual circuit if it is rated or designed for use with multiple appliances or when it's connected in a way that allows for additional load. A Branch Circuit, General-Purpose serves multiple loads or outlets and is not limited to a single utilization equipment, making it unsuitable for this specific definition. The term Branch Circuit alone is too vague as it does not adequately specify the relationship between the circuit and the utilization equipment, lacking the focus that "individual" provides.

Therefore, the designation "Branch Circuit, Individual" is accurate as it clearly conveys that the circuit is intended for a single load, enhancing safety and operational reliability in electrical systems.
