GFCI Outlet Wiring Problem
Electrical Project: How is a GFCI outlet wired for a 2-wire circuit that does not have a ground wire?
- I am trying to install a GFCI outlet to a 2-wire circuit that does not have a ground wire.
- When I use the white wire to connect the ground wire back to the box it is not working.
- I read an article about how to change a 2-wire receptacle with a ground for a GFCI, and it said it needed the green wire to connect the ground wire from the GFCI outlet back to the box.
- Will it make any difference if I use the white wire instead of the green wire?
This electrical wiring question came from Lindsey, a General Contractor in Queens, New York.
