	The GFCI monitors the [[electric current]] in the [[hot line]] and the [[neutral line]] (see Figure 1). When these two currents are equal operation is normal and there is no ground fault. However when these two values become unequal by as little as 4-5 [[ampere\|mA]] another path to the ground (ground fault) may be present, in this case the GFCI will open (with a response time of 1/30th of a second) thereby preventing [[shock hazard\|electric shock]] to a person.
