Which term describes all circuit conductors between service equipment and the final branch-circuit overcurrent device?

The term that describes all circuit conductors between service equipment and the final branch-circuit overcurrent device is a feeder. Feeders are essential components in electrical distribution systems, as they connect the service equipment, which is the main source of power, to branch circuits that deliver electricity to various outlets and devices.

In the context of the National Electrical Code, feeders carry power to distribution points, allowing for the regulation and protection of electrical circuits via overcurrent devices, such as circuit breakers. This classification is crucial for understanding electrical system design, ensuring that circuits are adequately protected and function within safety standards.

The other terms do not encompass the entire range of conductors in the specific way feeders do. A branch circuit refers to the conductors that extend beyond the last overcurrent device and deliver power to outlets or equipment, while a service line connects the distribution system to a utility supply. Distribution circuit generally refers to circuits that distribute power but may not specifically address the relationship to the service equipment and overcurrent devices as feeders do.
