About a week ago I asked about what wire I needed to run to an outdoor pool pump and got that part all taken care of thanks to the guys on here. I mounted a single gang pvc box to a fence post by the pool, ran 3/4" conduit from that box to the garage with a LB and then pulled 3 thhn wires threw this. Now I need to finish getting power out ther and have a few question. I have a sub panel in my garage where I will be getting power from. This is my plan so tell me if I am good or need to make some changes please. From the panel will be 20 amp breaker, 12-2 romex to a junction box attached to the LB. In this junction box I will go from romex to the stranded wire that runs to the pvc box by the pool. I bought a 20 amp GFCI for the box and a weather proof cover. The question I have is in my question about the wire someone mentioned the gfci has to be before the wire goes into the ground. So should I put the gfci in the junction box in the garage and then another out by the pool? Or a gfci in the garage and a regular outlet by the pool? Thanks for any help with this.

1 GFCI is all you need.Put the GFCI in the junction box in the garage or get a GFCI breaker and a regular outlet by the pool with a In-use cover. Put the GFCI sticker on In-use cover.

Thanks 300zx, I'll see how much a gfci breaker is and probably go that route just for ease when it trips. I do have an in use cover so the cord will stay plugged in and the pump has a timer.

, ran 3/4" conduit from that box to the garage with a LB and then pulled 3 thhn wires threw this.

I hope they are also rated THWN for wet rated - if your conduit is buried at all

I prefer the GFCI in anice dry location like the garage
I hate to be outside & have to reset a GFCI - rain...wet grass...wet from pool...etc

 

[ponch37300]

Scuba Dave, the wire is rated for thwn. In my last post about which wire to use someone stated that thhn is also rated for thwn. The label on the wire states thhn, thwn and some others. I agree about the gfci in the garage and unless the breaker is crazy expensive that is the route I will take. If the breaker is to expensive I will stick the gfci I have in a box in the garage.

GFCI breakers are maybe $25-35 last time I checked
The outlets - I bought a bunch - were maybe $3 each
I have a large Halloween/Christmas display so I have a lot of outside circuits

 

[ponch37300]

I just checked and it's 65 bucks for a square d 20 amp QO breaker. That's a little high for me so I will just use the regular breaker I bought and put a gfci outlet inside the garage.

Can I use the LB to make my splice from romex to stranded wire?

Thanks for the help

This thread will help :yes: http://www.diychatroom.com/f18/when-wire-needs-outdoor-direct-burial-rated-38543/

 

[ponch37300]

Thanks for that link. So I will look for the cu in listed inside the LB tomorrow and from what I understood if it has the cu in listed I can use it as a junction box. Thanks

Put the GFCI recep before the underground run and it only has to be 12" deep.

Put it at the pump location and it's 18"


And.....don't hack it up by making splices in the LB. :jester:

Just use a proper JB. It's no more expensive.

 

[ponch37300]

I know it's no more expensive to use a junction box but I already have the LB mounted and glued to the pvc and the stranded wire pulled from the pump to the garage. So my options are to splice in the LB or run conduit from the LB into the garage to a junction box and make the splice there. I don't know of an easy way to run conduit from the end of the LB sticking into the garage to a junction box. The walls are only 2x4 and the 90 elbows the sell would stick out of the walls. Is there a way to connect 1/2" seal tight flexable conduit to the 3/4" LB? Thanks

Jumped the gun there Sparky Jr :laughing:


Is the interior garage wall open?

Is the hole cut in the exterior wall?

Now much wire is sticking out of the LB?

How high off the ground is the LB?

Is it a plastic LB?

Now much wire is sticking out of the LB? I left about 10 feet

How high off the ground is the LB? about 18"

Is it a plastic LB? LB is 3/4" PVC

I thought I had asked enough questions and knew what I needed but guess not!!!

 

[220/221]

Use a short piece of PVC from the LB into the back of a 4 square deep box/single gang mud ring, mounted in the garage wall. Install the GFCI recep in the 4s box.

Use conduit (instead of NM) from the panel to the 4s box and you will have future accesss from panel to back yard box.

Thanks for all your help. Think I have it figured out now(hopefully)!!!

Good ole search button works....

I bought a 20AMP GFI breaker for my pool going in next week. Can I just run my 12-2 (insulated underground wire) in conduit to a regular 20AMP receptable? IS a GFI necessary?

lf you bought GFCI receptacles for $3 each they are older models that do not meet newer specs. I see them on eBay all the time.

If you have a GFI breaker, then the entire circuit is GFI protected. A non-GFI receptacle is perfectly fine.
