Tip & How-To about Electrical Supplies

Wiring a GFIC alternative.

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.

installing arc fault interrupter with ground fault

If you meant arch fault with ground fault then no, the two types interfere with each other and trip the breaker as one senses an arch and the other grounding.
If you meant ground fault breaker with a GFCI. receptacle, you only need one of the two, either GFCI. breaker or receptacle.

and for circuits, you can put up to 12 devices (i.e receptacle, light)assuming they consume 1 amp each. Anything over 12 amps or 80% of the rating on the breaker, it will trip/reset.
Or if your talking about wires on a breaker then no more than 2 wires recommended. Try adding a junction box outside the panel if your trying to add other branch circuits or tap off of a receptacle.

installing arc fault interrupter with ground fault

Question is vague. Arc fault and ground fault are slightly different.

Are you installing arc fault breaker?
http://waterheatertimer.org/How-to-wire-GFCI.html#arc-fault
http://waterheatertimer.org/How-to-replace-circuit-breaker.html

Code says Maximum 12 boxes per circuit breaker.

Arc fault breaker and GFCI outlet in bathroom?
>>> do not connect this way.
Do not install 2 fault protections on same circuit.
Install the arc fault circuit breaker, and then remove bathroom GFCI, and replace with ordinary outlet, or switch-outlet.

How many outlets can be connected to a bathroom GFCI?
It depends on total boxes on circuit.
Count the boxes. Max 12 boxes per circuit breaker.

How many amps can be connected to 15 amp device?
15 x 80% = 12 amps
Electricians use 80% rule to calculate safe maximum

what is wrong when you install a GFI outlet and the green light in the corner goes on than goes right back off than when you try and plug something in the outlet it doesn't have power?

It means that the outlet has tripped. There are one of three problems which you can check. 1. The outlet was wired wrong. On many new GFCI receptacles if the wiring is incorrect the receptacle will trip and not allow you to use it. Proper wiring methods can be found by searching in your search bar "how to wire a gfci". It is possible that what was plugged in went over the amp rating of the GFCI. causing it to trip (note: not as likely as your main circuit breaker would have tripped first). The only other things, which has happened to me a lot is the outlet can be super sensitive to current change. GFCI measure high and quick rises in current. If it is too sensitive to the rise in current the receptacle will trip. In this case it will need replacement, and the store will exchange it for you free of charge.

WIRING DIAGRAM FOR HOUSE

I think you mean a grund fault interrupter type breaker or receptacle.

The ground fault breakers fit into a regular box and they snap over the HOT input power tab like miost breakers AND they have a white pigtail wire that connects to the neutral bar in the panel.

The branch circuit that is fed from this breaker has BOTH the hot and the neutral connecting to the breaker as the breaker has two terminals for the purpose. The grounding wire of the branch circuit still goes to tthe ground bar in the panel.

For a GFCI receptacle, the branch circuit feeds the terminals labeled "LINE" and if other receptacles are to be protected by this device, they have their circuits continued from the terminals on the receptacle labeled "{OAD".
