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.
The GFCI is rated to trip quickly enough to prevent an electrical incident. If it is properly installed and maintained, this will happen as soon as the faulty tool is plugged in. If the grounding conductor is not intact or of low-impedance, the GFCI may not trip until a person provides a path.
