Marina Ground Fault Control Panel

MARINA GROUND FAULT CONTROL PANEL

MEE GFCI control panels detect dangerous ground leakage currents in marina shore power electrical systems and fulfill the latest publication of NEC Article 555.3 entitled “Ground Fault-Protection.” All models are factory pre-set from 5mA to 5A based on customer and/or project requirements. All models feature rugged water-tight NEMA 4X rated nonmetallic enclosures, with test and reset buttons, and power and alarm LED pilot lights for unmistakable indication of a ground fault event.

Function of the Marina Ground Fault Control Panel

In a typical marina application, the secondary of the marina distribution transformer provides grounded 120/240 VAC or 208Y/120 VAC power to the power pedestals. When monitoring the main feeder, the Marina Ground Fault Control Panel will be connected to a Current Transformer (CT), which is placed around the NEUTRAL to GROUND main bonding jumper (if applicable) or all “HOT” conductors, plus the NEUTRAL conductor.

NOTE: the GROUND conductor is not placed through the CT. This will allow the control panel to detect all AC ground faults downstream of the CT, including any leakage current between the transformers and wiring to the power pedestals, and/or to any connected boat(s). Once the specified alarm leakage threshold has been detected, the device will illuminate the red LED pilot light and/or interrupt the circuit if connected to a shunt-trip circuit breaker.
