MARINA GROUND FAULT MONITOR

Eaton now offers a ground fault monitoring systems designed to detect fault currents in the AC shore power system that are too low to trip a circuit breaker. The Ground Fault Monitor helps reduce the risk of injury or property damage, which may result from stray fault currents. Our ground fault monitoring system provides information to the maintenance staff on the overall condition of the AC electrical system. The ground fault monitoring system operates 24-hours a day and can be monitored by non-technical personnel.

The monitor detects ground fault currents by means of current transformers (CT), which are placed around main or branch circuits. If a ground fault occurs, the CT will detect the amount of fault current and send a signal to the ground fault monitoring device where the amount of fault current is displayed with the faulty circuit identified. The detected fault can either activate an indicator alarm or disconnect the faulted circuit. Standard features include:

  • Underwriters Laboratories listed current transformers
  • Adjustable trip level 10mAmps to 10 Amps
  • Current transformers up to 8 1/4” diameter
  • Visual and/or audible alarm
  • Housing of fiberglass (shown), or powder coated stainless steel available
