Tip & How-To about Electrical Supplies
When wiring a GFCI (Ground Fault Interrupter Circuit) receptacle you would normally connect the wire coming from the service panel or the hot wire to the LINE connection at the GFCI and then connect the other receptacles you wish to protect to the LOAD side on the GFCI. But let's say you have installed a GFCI in a garage circuit and want to run a wire to the garage door opener from that circuit without the garage door opener receptacle being protected by the GFCI but still want all other receptacles protected. Reason being that the garage door opener will trip the GFCI more often than not. You may also want to have a receptacle for a freezer in the garage. You do not want that freezer protected by the GFCI circuit as it may trip without your knowledge and cause all the food to spoil. Warning: Only install a single plug receptacle for the freezer and not a double plug receptacle. That way only one thing, the freezer, can be plugged into this receptacle as it is not GFCI protected. The way to avoid the breaker tripping is to connect the garage door opener & freezer receptacle to the LINE side of the GFCI. This way it is not protected by the GFCI and there is no danger of that receptacle loosing power due to a tripped breaker on the GFCI. When the GFCI trips power will still be available at any receptacle connected on the line side. On any GFCI you can connect two sets of wires to the LINE side. If you have more than two you will have to connect those together under a wire nut and then use a jumper wire to connect to the LINE on the GFCI. Look at the photo and you will see the 2 sets of holes to connect at the LINE side (Bottom) on the back of the GFCI receptacle. There are also 2 sets of holes to connect on the LOAD side (Upper). Of course you would use a wire nut and jumper to connect all the ground wires.
