House Branch Circuit Diagram. Each circuit can be traced from its beginning in the service panel or subpanel through various receptacles fixtures and or appliances and back. The 14 2 awg cable for this circuit includes 2 conductors and 1 ground wire.
A multi wire branch circuit in a residential dwelling contains two 120v wires of different phases a and b phase and share one neutral wire as return current. Wiring for a 15 amp 120 volt circuit breaker. Individual branch circuit breakers control each circuit.
In house wiring a circuit usually indicates a group of lights or receptacles connected along such a path.
Branch circuits for 120 volt circuits are usually 15 amp or 20 amp circuits although occasionally they will be larger than that. When a three wire nm cable is used for this type of circuit. This wiring diagram illustrates installing a 15 amp circuit breaker for a 120 volt branch circuit. Both 120 volt and 240 volt branch circuits can vary in the amount of power they deliver a quantity measured by amperage.
