I was replacing a GFCI, and noticed 7 total wires:
2 load wires
4 line wires
It is my understanding that the line wires are the power source coming to the GFCI, and the load wires are providing power to the next receptacle (or switch, etc).
Does anyone know why there is 4 line wires? The instructions on the new GFCI explicitly stated not to use if more than 4 total wires (e.g., 2 line, 2 load) not including the ground.
