How do I know if a wire is load or line?
Load Wire – Generally connected to the top half of your switch. If the wire is coming from the top of the switch box, it is likely your load wire. Line Wire – Generally connected to the bottom half of your switch. In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol.
Which wire is line and which is load?
The line side of an outlet is where you connect the incoming source power. The load side is where the power leaves the device (or electrical box) and travels down the circuit.
What happens if you mix up line and load?
If the load and line wiring gets messed up, a ground fault (radio in the tub) won’t trip the GFCI. There is no protection; there’s only the appearance of protection. The GFCI is a booby trap.
Is the load wire the same as the hot wire?
Line is the wire that goes from a source to a switch. It’s upstream of the switched device. Line is very hot. The wire from the switch to the device is called load.
