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 15 amp GFCI breakers installed on the general
circuit, since the exterior breaker is on this circuit. The
breaker replaced the standard TQL-15 amp breaker.
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.
