A very recent book on wiring shows two GFCI protected receptacles wired together in close proximity over a countertop.
I expected the wiring would be:
- power-in connected to LINE screws on 1st GFCI receptacle
- cable connected to LOAD screws in 1st GFCI receptacle and runs to 2nd plain receptacle It seems like this protects both. However, the book suggest using two GFCI receptacles wired like this:
- power-in pigtailed to LINE screws on 1st GFCI receptacle and cable out heading to 2nd GFCI receptacle
- at 2nd GFCI receptacle, connect the cable to LINE screws.
Why are two GFCI receptacles used instead of one GFCI which protects itself and a second plain receptacle?
I have attached a picture. Please tell me if that violates any copyright laws so I can remove the picture. After studying the picture, I wonder if the answer to my own question is that this wiring allows the circuit to be extended beyond the GFCI receptacles using the same 12/2 cable.
