Leakage current protection system for marinas

A leakage current protection system, comprising:

• a current transformer adapted to have a plurality of current-carrying conductors pass there through, the conductors extending from first ends thereof to second ends thereof, the first ends adapted to be coupled to a plurality of load receptacles, said current transformer detecting an aggregate differential current between the conductors;
• a plurality of circuit breakers, each of said circuit breakers adapted to be coupled to the second ends of the conductors coupled to a corresponding one of the load receptacles, each of said circuit breakers further adapted to be coupled to a source of electrical power;
• a differential current monitor coupled to said current transformer for generating a signal when said aggregate differential current exceeds a threshold current;
• a plurality of shunt-trips coupled to said differential current monitor for receiving said signal and being actuated thereby, each of said shunt-trips coupled to a corresponding one of said circuit breakers for opening said corresponding one of said circuit breakers when said signal is received, wherein said plurality of circuit breakers are opened simultaneously;
• a circuit coupled to said differential current monitor and adapted to be coupled to the source of electrical power, said circuit including a switch for opening and closing said circuit wherein, when said switch is operated for closing said circuit, said circuit generates a test current for receipt by said differential current monitor, said test current exceeding said threshold current wherein said plurality of circuit breakers are opened simultaneously;
• and
• a rigid panel for mounting said differential current monitor, said shunt-trips, and said circuit breakers to be accessible at a front face of said panel.

A leakage current protection system for a facility supplying electrical power for vessels, comprising:

• a housing;
• a plurality of twist-lock load receptacles coupled to said housing;
• a bus bar mounted in said housing, said bus bar adapted to have a facility's electrical power coupled thereto;
• a plurality of current-carrying conductors disposed within said housing and coupling each of said receptacles to said bus bar;
• a current transformer disposed about said current-carrying conductors from each of said receptacles, said current transformer detecting an aggregate differential current between all of said current-carrying conductors;
• a plurality of circuit breakers mounted in said housing, each of said circuit breakers disposed between said current transformer and said bus bar and electrically coupled to a corresponding one of said receptacles and said bus bar;
• a differential current monitor mounted in said housing and coupled to said current transformer for generating a signal when said aggregate differential current exceeds a threshold current;
• and
• a plurality of shunt-trips mounted in said housing and coupled to said differential current monitor for receiving said signal and being actuated thereby, each of said shunt-trips coupled to a corresponding one of said circuit breakers for opening said corresponding one of said circuit breakers when said signal is received wherein said plurality of circuit breakers are opened simultaneously.
