An individual branch circuit supplies which of the following?

An individual branch circuit is designed to supply power to only one piece of utilization equipment. This means that it provides a dedicated electrical supply to a specific appliance, tool, or device, ensuring that it receives adequate power without sharing the circuit with other devices or equipment. This setup is particularly important for high-demand appliances that require a consistent and reliable power source, which can help prevent overloading and potential circuit failures.

In contrast, the other options refer to configurations that would typically involve shared circuits or multiple devices using the same power supply. While circuits that serve multiple pieces of equipment or multiple devices are common in residential and commercial wiring, these scenarios do not align with the definition of an individual branch circuit. Additionally, lighting fixtures, while they can be connected on a separate circuit, often share that circuit with other fixtures or devices, further highlighting that option B is the most accurate in the context of individual branch circuits.
