Can a gfi be used without a ground wire?

Answer by  mike1979 (13)

You can use a gfci receptacle without a ground wire. However along with the receptacle there should be little stickers, one of which stating that the receptacle is not grounded. The reason you can do this is that a gfci receptacle reads the amperage difference between your "hot" conductor, and your "neutral" conductor.

No, a GFCI is designed to work with ground wire. The lack of a ground wire will cause the product to NOT work properly and have a higher chance of a fire hazard.

A GFI is used to check if the power is at all shorted to ground. A two prong AC plug can be used with a GFI even though it does not have a gound wire. If either leg gets short the GFI will trip.

No. a ground wire is required to complete an electrical circuit,in order,to allow the current flowing from the hot wires to return to the power station.
