    hello all,
    I have had great advice from this site and I need it again.
    I have a two wire outlet in the attic . I have guitar amp that I want to put there. The amp has three prongs . Since running a ground to the water pipe is near impossible. But I know that I can put in a gfi outlet with "no equipment ground" . Can I put a 14 ga single wire from the ground screw on the outlet to the white neutral screw will that provide equipment ground?. Or is it code for massachusetts? Please help!!!!

    The whole idea of the safety ground is to have a TOTALLY independent safety path back to the breaker/fuse panel to ensure that the breaker/fuse will trip if there is a short. A jumper between the neutral and ground would NOT perform this safety feature. Use a GFCI recepticle, if you must emulate a ground there, or rewire the whole circuit. The GFCI essentially does the same thing, but electronically, rather than mechanically.
