An ELCI is a type of ground fault protection device that disconnects the boat from shore power when a “fault” current is detected, isolating electrical equipment on the boat from damaging current. “Ground fault” is the unintended connection of the AC “hot” and anything other than the AC “neutral”. When connected to shore power, “fault” circumstances can cause AC return current to travel through the safety ground or even the water. This can cause significant damage to electrical systems on the boat, and can be lethal to people and wildlife as well.

Our ELCI panels meet all of the ABYC E11 requirements for ground fault protection of shore power inputs: ABYC GFCI Rules:

E– Receptacles installed in a head, galley, machinery space, or on a weather deck, the receptacle shall be protected by a Type A (nominal 5 milliamperes) Ground Fault Circuit Interrupter (GFCI).


E-11.11.1: An Equipment Leakage Circuit Interrupter (ELCI) shall be installed with or in addition to the main shore power disconnect circuit breaker(s) or at the additional overcurrent protection as required by E- whichever is closer to the shore power connection. E- If the location of the main shore power disconnect circuit breaker is in excess of 10 feet (three meters) from the shore power inlet or the electrical attachment point of a permanently installed shore power cord, additional fuses or circuit breakers shall be provided within 10 feet (three meters) of the inlet or attachment point to the electrical system of the boat. Measurement is made along the conductors.
