Here is a situation. What do you think? There is a partial renovation going on and it touches the powder room. The sheet rock has just a little coming off so the homeowner adds a 2 gang box which will hold the switch to the existing light and a new GFCI receptacle. The GFI though is on the existing 14 ga circuit. So I tell him that all bath recept. should be on 20 amp feeds. The homeowner says that the house is on a slab, and the rest of the house is finished. He can't get to the panel with out major damage to the house. He said if that was the case, then he wouldn't install the receptacle. He would just leave it out. What would you do?
