I just recently purchased an older home in Chicago, Il built in 1972 and I am replacing an outlet with a GFCI receptacle. When I pulled the original outlet from the conduit box. I found 9 wires on the outlet. 4 black and 5 white. One of the black wires is hot and one white is also hot. The instruction that came with the GFCI read I should call an electrician, but I am trying to avoid having to do that.
If you want all wires to go through the GFCI
- Connect the hot black and white to the LINE terminals
- Cut a short piece of white and a short piece of black and connect to the LOAD terminals
- Connect the other end of the short black and all the other blacks together with a wire nut. Do the same with the whites.
If you want some connections to not go through the GFCI
- Cut two short pieces of black and two short pieces of white
- Connect these to the LINE and LOAD terminals
- Connect the short wires connected to the LINE terminal to the incoming hot wires and the wires you DO NOT WANT to go through the GFCI with wire nut connectors
- Connect the short wires connected to the LOAD terminals to wires you DO WANT to go through the GFCI with wire nut connectors
