RESIDUAL CURRENT CIRCUIT BREAKER (BLUE SEA SYSTEMS) 30 2 pole ELCI Main A-Series 120V AC per pole<BR>Flat Rocker

Residual Current Devices (RCDs) respond to leakage of electrical current outside of the intended circuit path. When the RCD function is combined with a circuit breaker for over current protection, the device is often referred to as an RCBO. In the USA, a device that trips on leakages of nominally 5mA and meets certain standards is called a Ground Fault Circuit Interrupter (GFCI). A device meeting the same standards but with a trip level of 30mA is called an Equipment Leakage Circuit Interrupter (ELCI). These devices provide GFCI Branch or ELCI Main functions and circuit protection in panel mounted breakers. For installation in a power distribution panel. Trips on short circuit, overload, or leakage to ground
GFCI Branch Provides overcurrent and leakage protection per ABYC E-11 for head, galley, machinery and weather deck receptacles
ELCI Main Provides overcurrent and leakage protection per ABYC E-11 for whole boat shore power protection
