I have an older bathroom, ( 1965) that is getting a remodel. The existing romex is 2-wire. I want to tie into that and feed a fart fan, light switch and a GFI plug.
What do I do with the ground on the new romex with a ground wire. One guy told me to coneect the Nuetral, (white) with the ground . Is this true. I am using all plastic boxes. Is 14 gauge ok?
