MARINA GROUND FAULT CONTROL PANELS

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
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.

GFR 480-1 Sentinel II Ground Fault Relay

Marina Electrical Equipment utilizes the latest in ground-fault detection and relay technology to provide accurate and fast-responding ground fault protection. The National Electric Code requires ground fault protection not exceeding 30 milliamps (mA) at the shore power outlet.
The GFR480-1 Ground Fault Relay is an economical and sensible solution to provide the utmost in personnel or equipment protection.

STANDARD FEATURES:

  • UL-Listed and marked, tested and certified to conform to UL Standard 1053 entitled “Ground Fault Relay Sensing Equipment” and CUL Standard C22.2 No. 144 entitled “Standard Ground Fault Circuit Interrupter.”
  • Modular DIN-rail mount design – GFR480-1, circuit breakers and shunt-trips are separate devices.
  • Cost-effective: worn or failing circuit breakers can be replaced separately since the GFR480-1 is modular, saving considerable cost.
  • Factory-set trip values at 5 mA, 30 mA & 100 mA.
  • External Test/Reset Button
  • Reliable and user-friendly
  • Provides clear audible and visible LED indication of ground faults, eliminating uncertainty of why circuit breakers tripped.
  • Designed to trip all circuit breakers serving one boat slip, allowing use of electrical cord splitter adapters without unwanted tripping as experienced with typical ground fault circuit breakers.

Input Voltages:

  • Single-phase 120VAC, 120/240VAC, 60 Hz.
  • Three-phase 120/208VAC, 277/480VAC, 480VAC, 60 Hz.
  • Input Current of 1-1200 amps

Input Protection:

  • Current-limiting flame proof resistor.
  • On-board resettable MOV for surge protection.
  • Fully operational between -20°F (-30°C) to 140°F (60°C).
  • Limited 1-year warranty.
