How To Connect 2 Ground Wires-1 Outlet?
Built new room on rear of house, knowledgeable friend did the wiring. Left the outlets/switches for me.
Wire is 12 ga. Romex, outlets are 20, amp. Hmmm, some of the single boxes have two wires--2 black, 2 white, and 2 bare grounds.
No problem with the power wires, each has its own screw. But there's only one ground screw, and no way can I get two 12 ga. wires around it.
So, do I twist the two bare wires together, leaving one longer to wrap the screw? Can't see any other way.
