Which term describes the wiring that runs from the last protective device to the outlets?

• A. Feeder
• B. Branch circuit
• C. Service conductors
• D. Lateral

Answer: (B)

In electrical wiring, the segment that runs from the last protective device (like a circuit breaker) to the outlets is called a branch circuit. This portion is dedicated to delivering power to a specific set of outlets or loads and is protected by that device. It differs from feeders, which move power from the service equipment to distribution points, from service conductors, which bring power from the utility to the main disconnect, and from lateral, which isn’t the standard term used for this residential wiring segment. So the wiring from the last protective device to the outlets is best described as a branch circuit.
