Here’s an example below of two GFCI’s from different manufacturers that look similar from the front, with ground hole on bottom, but must be wired differently in back. If you just match top and bottom wire sets, you may get it wrong. If there are no other receptacles on the circuit, then it will only have two LINE wiresĪnd this is important: it’s not enough to just mark the top two wires in the old receptacle and place them in the top position in the replacement, because some manufacturers put the LINE set on top, and others put the LINE set on the bottom. The LINE wires bring the electrcity to the receptacle and the LOAD wires connect to another receptacle downstream in the circuit. Also, be sure to mark which pair of wires are LINE and which are LOAD before removing them from the old receptacle. You need to connect the black (hot) wires to the brass screws and white (neutral) wires to the silver screws. The reset button won't work and the receptacle remains dead, even though the wiring to it is live. A GFCI-receptacle right out of the box is tripped, and will not reset and function until it is wired correctly and the power turned back on.
