GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
Many states require trailers which are sold in their state, and which have exterior 110 volt receptacles, to have a ground fault circuit interrupter.
Trailers manufactured for sale in these states have type THQL IS amp GFCI breakers installed on the general circuit, since the exterior breaker is on this circuit. The breaker replaced the standard
When properly installed, the GFCI circuit breaker provides reliable overload and short circuit protection PLUS protection from Ground Faults that might result from contact with a “HOT”’ load wire and ground.
IMPORTANT NOTE: The GFCI circuit breaker will NOT reduce shock hazard if contact is made between a “HOT” load wire and a neutral wire or 2 “HOT” load wires.
Each GFCI circuit breaker is calibrated to trip with a ground current of 5 milliamperes or more. Since most persons can feel as little as 2 milliamperes, a distinct shock may be felt if the need for protection exists. However, the shock should be of such short duration that the effects would be reduced to less than the normally dangerous level. However, persons with acute heart problems or other conditions that can make a person particularly susceptible to electric shock may still be seriously injured.
