A leakage current protection system includes a current transformer disposed about current-carrying conductors that extend from first ends to second ends. The first ends are coupled to load receptacles. The current transformer detects an aggregate differential current between the conductors. Each of a plurality of circuit breakers is coupled to the second ends of the conductors that are coupled to a corresponding one of the load receptacles. Each circuit breaker is coupled to a source of electrical power. A differential current monitor coupled to the current transformer generates a signal when the aggregate differential current exceeds a threshold current. Each of a plurality of shunt-trips coupled to the differential current monitor receives the signal. Each of the shunt-trips opens a corresponding one of the circuit breakers when the signal is received so that all of the circuit breakers are opened simultaneously.
