What are branch circuit conductors used for?

Branch circuit conductors are specifically designed to carry electrical power from the service panel or distribution board to various points of utilization, such as outlets, light fixtures, and appliances. This means they function primarily as the wiring that connects individual devices to the electrical supply, facilitating the delivery of power where it is needed in a residential or commercial setup.

In residential systems, these conductors play a crucial role in ensuring that power is distributed safely and efficiently to enhance the functionality of devices. They are sized and selected based on the load requirements and the length of the run, adhering to local electrical codes for safety.

Though feeding power to service panels is critical, this is primarily the job of feeder conductors rather than branch circuit conductors. Similarly, while branch circuit conductors can be connected to light switches, they are not solely defined by this function. Grounding systems serve a fundamentally different purpose, focusing on safety and fault current management, rather than power distribution. Thus, the most accurate understanding is that branch circuit conductors are directly associated with wiring to outlets and other load points.
