A detached garage has a breaker panel which is connected to a breaker in the house breaker panel. What type of circuit is the garage breaker panel considered?

• A. Branch
• B. Feeder
• C. Service
• D. Junction

Answer: (A)

The main idea is how circuits are classified in a power distribution system. A branch circuit is essentially a path that leaves the first overcurrent device and goes on to feed outlets, lights, or a device load. In this setup, power leaves the house panel through a breaker and arrives at the panel in the detached garage. That run functions as the circuit that feeds the garage’s distribution point. From there, the garage panel itself supplies its own branch circuits to lights and receptacles inside the garage. So the connection to the garage panel is viewed as a branch circuit—the path from the house panel to the garage panel acts as one circuit that ends at that separate distribution point, which then distributes further. A service circuit would be about the main service entrance and the service disconnect, which is not what this particular run is. A feeder would typically describe the conductors that carry power from service equipment to a subpanel or distribution point, often across a larger scope; but in this context the test emphasizes the branch-path to the garage panel itself. A junction is simply a point where conductors meet, not a circuit type.
