If there was a GFCI outlet or breaker it would only pass mili-amp range before tripping. For those that don't know a GFCI outlet/breaker watch the power leaving on the hot side and the power coming back on the neutral side. If they don't match(with in mili-amp range) then it will assume power is leaking some where and trip.
