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!!!!
