WebNov 13, 2013 · The breaker never tripped. Do breakers have more tolerance, thus slower to trip, when there is that much distance? The breaker doesn't change, what does change is the amount of fault current that flows. The longer the run the more "ohm's per foot" are in the path which means more overall resistance. The more resistance the less current will flow. rdm to dfw flightsWeb(21).
