Wiring for GFCI Outlets
How can I wire a GFCI Outlet with no ground wire? Installing a GFCI Receptacle Where a Ground is Not Available.
GFI Outlet Wiring
I was trying to change two plugs to GFCI plugs.
- Each is on a different circuit. The first plug is the only one on the circuit.
- There are only 2 wires, no ground. Can I attach these to the GFCI with no ground?
- Will it work properly? The second plug has another plug on the line after it, so 2 wires in and 2 wires out, but again no ground.
- This is in the kitchen of my office building. The city wants these to be both GFCI. Do I need to add a ground?
This electrical wiring question came from: Dan, a Homeowner from Santa Maria, California.
Thanks for your electrical wiring question Dan.
