When it comes to ground fault circuit interrupter outlets, commonly known as GFCI outlets, there is always a question as to how to connect the wires to them. You see, GFCI's have two terminals on each side, one side the neutral connection and the other the hot wire connection, and a ground terminal on one end.
One half of the outlet connection is labeled LINE and the other LOAD. To the unfamiliar eye, they appear to connect to the same point, and in fact, the terminal screws are the same color, giving the appearance that they are a common connection. The truth is that these connections are very different and I'm going to tell you the difference between line and load connections.
