Best Answer

Install the GFCI outlet is a location near the hot tub where it can be accessed and tub plugged in. Connect ground wire to green ground screw. Connect black/white wires to LINE side of outlet. Black goes to copper screw, white goes to silver screw. You connect the wires by inserting them into the holes marked LINE and then tightening the screws down tight.

Will mixing 12 gauge wiring with 14 gauge wiring cause a gfci to trip?

no it will only decrease the current carrying capability


What could cause an outdoor outlet to lose power if the outlet is new and the wires are getting power and the breaker has not popped?

Most outdoor outlets are on a GFCI device. Depending on when your house was wired the outside plugs may be fed from the GFCI in the bathroom. The method used was to take the downstream side of the bathroom GFCI and run it to the outside plugs all around the house. If you want to delve into this further open a discuss question page


What would be the correct wiring for 3 sets of wires into a GFCI outlet?

I'm assuming your 3 sets of wires are black or red, or some other color normally associated with the "hot" wire, a white for neutral and a green or bare conductor for ground. If your GFCI protects only itself and no other receptacles, you splice all the wires of the same color together and attach 'pig tails' to your splice to connect to the GFCI. If your GFCI protects other receptacles 'down stream', you connect only the hot and neutral feed from the panel to the line side of the receptacle. Then you splice the others together as described above and connect your pig tails to the load side. "Line" and "load" should be clearly marked on the GFCI. Your ground in this case is still all spliced together with a pigtail for connection to the GFCI. Line is from the panel. Load is to other receptacles. Getting these reversed will prohibit your GFCI from functioning properly.


How much amperage is needed to trip a 20amp GFCI outlet?

A GFCI trips when it detects a difference in the amperage going to the outlet and what is coming back. Even 4-6 miliamps difference will trip the outlet.


Why is Earthing provided in the electrical wiring of a builiding?

The chassis of electrical equipment is typically connected to the Earth through the Ground (Earth) terminal of the electrical outlet. This is why building wiring should (or must, in many areas) include an on-site Earth ground connection. Earthing of equipment chassis is a safety measure taken to help prevent electrical shock in the event of an insulation failure or a short circuit. If there were no chassis-ground connection, a hot wire which accidentally comes in contact with the chassis could cause the user to get a serious shock. If there's no Earth connection available, use a GFCI outlet to help prevent electrocution.

Can a circuit with a GFCI be shared at the box?

Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.

What is the wiring and gfci for a bathtab jacuzzi?

Connect incoming power to the line side of GFCI outlet and plug Jacuzzi into the outlet. Must be on a dedicated circuit. If it has a pump and heater then each one must be on dedicated GFCI protected circuit.


How do you wire an outdoor timer into a GFCI outlet?

I assume you are hard wiring it and not plugging it in. The power coming into the GFCI outlet connects to the line side of the GFCI outlet. If you want the outdoor timer protected by the GFCI then connect the wire going to the timer to the load side of the outlet. If you do not want the timer protected then connect it to the line side. On the back of the GFCI if you look closely you will see Line & Load marked on the back.


Where is a GFCI not needed?

In rooms without exposure to water such as a bedroom or living room. Typically, GFCI is used in bathrooms, kitchens, garages, outdoors and sometimes basements.

Why does the reset button on a wall outlet pop out when something is plugged into it?

Assume this is a ground fault circuit interrupter (GFCI) outlet. The GFCI looks for current that is flowing to ground, in a manner that could result in electrical shock to a user. The appliance that is being plugged in could be defective, the wiring connected to the load side of the GFCI may be incorrect, or the GFCI outlet could be defective. Try using another appliance. If the GFCI holds, the first appliance is most likely the cause.

Do you need a gfci outlet if you have a gfci breaker?

Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.


Where shouldn't you use a gfci?

Since GFCI's are more expensive, you wouldn't want to use them in any place where they are not required. In many old homes, GFCI's are sometimes used for outlets in bedrooms and living rooms where proper grounding is necessary (for computers, TV's, other electronics), but not available because of the age of the wiring. You would also want to avoid cramming a GFCI into a box that is too small to accommodate the bulkier GFCI outlet. You should first replace the box to a larger one.
