A friend of mine who is a mason received an OSHA fine for not having GFI protection on a 220 volt wet table saw on the jobsite. The 220 volt line comes out of a 30 amp breaker panel consisting of 2 hot wires and a ground and is attached to the saw with a male and female plug. My understanding is that GFI's monitor the neutral. The saw does not require a neutral in order to work, and GFI's won't work on motors. Is there a way to have GFI protection on the saw?
