I have been suddenly thrust into my first in-ground (fiberglass, one-piece) pool job.
I have 2 questions...
1.How does a strain relief (680.24(B)(E) connect to the inside of a raised deck box?
2.Is potting compound only required at the niche terminal? Is duct seal OK at the raised deck box?

Thanks

Redsy,

The Deck Boxes come with the strain-relief and screws to mount it. It will probably be obvious as soon as uyou open the box.

Potting compound is required for the #8 ground if the forming shell is metal and the raceway is NM. Duct seal can be used to seal the raceway from the forming shell in the deck box. As Bill said it should be obvious how the strain relief mounts.

Too quick for me,

I removed my comment/question about the potting Compound and Duc seal as I have never seen either used. All the pools I've done always had a metal conduit.

Bill:
Just a point; out of 40-50 inground pools that I have inspected this season, NONE had any metalic conduit. You're using RGC???

Caselec has the sealing answered. If there's no compound at the luminaire shell and the #8 grd conn., and no duct seal (or compound) at the deck box, then it's red sticker time.

John,

Actually it's been a few years now since I've done a Pool or Hot Tub. The amount of time and effort spent on estimates to the Consumer for these things wasn't paying off so it was easy to give up.

All the in-ground pools I've done had Brass Conduit to the wet niche, no GRC. The Pool guys installed it, bent and threaded it for us. So we just took it from there.

Boy, do I hear you on the "waste of time"

That's why I stay far, far away from resi.

As long as the comm stays steady, along with the site lighting, I don't need the run-arounds

"What do you mean, $100-$150.00 to install the $29 paddle fan I just bought at the big box store??"

Brass pipe?? OK, I have not seen that in a long, long time. Maybe Harold has!

Here is a pic of the approved pool box that has been talked about. Look closely and you will see the strain relief on the cord.
