Have one of the old circuits with a single receptacle on the bottom and the reset on the top. I need to replace due to bathroom paint color change. I tried to buy the exact same socket to make it simple, but do they have them? F no! I buy a CFGI with a double receptacle. My old switch had two black wires connected to one side (on separate terminals) and the same for two white wires connected to the other side of the switch. Also has a ground on its own terminal. Hmm, pretty simple, should be no issue to replace. I wire the new switch the exact same way and does it work? F no! I then transpose the black wires top to bottom and do the same for the whites and does it work? F no! Next I put the old switch back in and it works with the wires transposed or not. Then I try another new switch, just in case the first one was defective, and does it work? F no! Does anyone know what is wrong?
