The special-purpose GFCI category is for applications where equipment grounding is provided by the NEC or where the voltage is greater than 150V. Specialty GFCIs trip when the current to ground has a value of 15 to 20 mA.
GFIs operate by detecting a difference in the current between the hot wire--the wire that provides the current, and the neutral or ground wire, through which the current is supposed to return. If the circuit is leaking, the current will be higher in the hot wire than in the ground wire.A leaking circuit is a sign of a short circuit, or possibly someone getting shocked or electrocuted. GFIs are also sometimes referred to as GFCIs, or ground-fault current interrupters. This outlet does not have a GFI.f the circuit is leaking, the current will be higher in the hot wire than in the ground wire.
