Which equipment distributes power from the service to the branch circuits within a building?

• A. Branch Circuits
• B. Grounding Electrode System
• C. Service Disconnect
• D. Distribution Equipment

Answer: (D)

The main idea is how power is routed from the service to the various branch circuits inside a building. Distribution equipment is the hardware that takes the incoming service power and splits it to feed the multiple branch circuits, usually through panel boards or switchgear, while also providing overcurrent protection for each branch. Branch circuits are the individual paths that carry power to specific loads, not the distribution point itself. The grounding electrode system is for grounding, not delivering power to loads, and the service disconnect is the main shutoff for the entire service rather than the device that distributes power to each branch circuit.
