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.
How the GFCI Works. In the home's wiring system, the GFCI constantly monitors electricity flowing in a circuit, to sense any loss of current. If the current flowing through the circuit differs by a small amount from that returning, the GFCI quickly switches off power to that circuit.
