A circuit breaker in series before the parallel branches can prevent overloads by automatically opening the circuit. A 15 A circuit operating at 120 V consumes 1,800 W of total power. P = VI = (120 V)(15 A) = 1,800 W. Total power in a parallel circuit is the sum of the power consumed on the individual branches.
