I just bought my house and I am replacing some of the outlets and switches. I have come across a dilemma that I can't seem to solve. I need to install a GFCI for my pool but for some reason the people who had the house before me had ran 12/3 wire to the outside of the house. Howe could I connect the GFCI to a 12/3 wire? Can I pigtail the red and black wires together and connect them to the hot terminal? Is there any way to connect this GFCI properly without having to run a whole new wire underground? Can I install a switch to somehow get around this dilemma?

Pool wiring is very technical and detailed. And it depends on the type of pool and the definitions of each type.

See

http://www.selfhelpandmore.com/homewiringusa/2002/accessory/index.htm

As your orginal question you did not indicate what this circuit is for?

Is it for 240 v loads or a a multi-wire circuit you can install a 120/240 2 pole GFCI breaker.

If it is just a mutli-wire circuit you can install two GFCI receptacles.

Pigtail the netural to two whites to feed the two GFCI's and connect one hot to one and the other hot to the second.

But read the requirements for the type of pool that you have. There is a good chance that the who thing has to be redone.

The outlet is for the pump for the pool. I tried going on that link that you posted but it doesn't seem to work. So it looks like the best solution would be to just have 2 gfci receptacles like you had stated.

I tried wiring the 2nd gfci like you had stated to the red and white wires while the first gfci was connected to the white and black.

The red wire is connected to one breaker and the black wire is connected to another breaker. I would think that if I have the gfci connect to the black and white wires it should be ok and I wouldn't have to worry about the red wire. For some reason the breaker with the black wire keeps tripping. The pump is rated for 9.6A and the breaker is rated 15A so it should be able to handle the load of the pump.

I can't seem to figure out what the problem is. Do you have any ideas or suggestions?

How are the red and black wires connected at the breakers? They need to be on breakers that are mounted one above the other so that each is on a different hot bus. Also, make sure you pigtailed the white to each GFCI as Bill directed.

I tried only using one receptacle, since that is all i need and connected the one GFCI to the black and white wires. For some reason the breaker still trips, but not right away. The pump is rated 9.6A and the breaker is 15A. Shouldn't this be ok? Could there be something else that is causing this breaker to trip? Something that is miswired somewhere?

The breaker could be bad. Replace it.

And when replacing it make sure that the wire is securely attached and that the it fits tightly on the bus and that there is no corrosion on the bus.

Bad connections generate extra heat that will make a breaker trip at lower than normal currents.

What about the motor. Check the label. Make sure that it is not a 230 volt motor. Or a dual voltage motor that is set on 230. Or it is a dual voltage and it take 9 amps at 240 and 18 at 120.

Try the motor on a different outlet to verify that it does start and run OK.

I tried the pump on another outlet and it works fine and the breaker doesnt trip. Do you think the problem is with the breaker or could it also be a problem with the wiring? Would the breaker trip if for some reason the wire was cut?

First I want to verify that the breaker(s) are not GFCI. That they do not have a test button.

If that is the case the only kind of wiring problem that will cause the breaker to trip would be if it was shorting. But then the breaker would be tripping without a load on it.

Is it possible that there is someother load on that circuit?

Only the outlet is a GFI, the breakers are standard non-GFI breakers. There is nothing else connected to this breaker. How would I know if the wire is shorted? Would it be connected to another wire (red or white)?

Is this an inground pool or above.......How far from the panel?

The wire ?.......a cable "12-3" /grnd.......what is the label.....UF or NM or ?......is it flat or round ?

Is it in conduit ?....metal or plastic....

How does the wire enter the panel and the waterproof box holding the GFCI ?( a clamp or conduit) What supports the box at the pool?

and slow down and check again.....Billhart's link works....just scroll down and select the type pool..........

"...measure once.....cut twice....throw that one away and cut a new one...."

This is an above ground pool. The pool is about 75 feet from the pool.

The wire is a 12/3 (red, white, black and ground). I am not home right now so I can't check the label on it until I get home. The cable is round.

The wire is run underground from the panel to the backyard without conduit and then where it gets by the pool it is in PVC conduit.

The wire enters the waterproof box through the conduit that is attached to the waterproof box. The box is mounted onto a pressure treated wood post.

I stand corrected, the link works now.

" The cable is round.......

Most round cables are for DRY use.....check your labeling.......

The round cable uses strings of paper to fill the cable sheath......water soaks into the cable causing problems......
