Hot Tub Wiring

<< < (3/4) > >>

Botswana:
this brings up another topic. Once the wiring enters the hot tub cabinet, does it technically need to be in codinuit anymore, or can be it free cables running into the spa circuit board.? My pvc stops at the hot tub cabinet

Not sure of the code.
Mine is pvc through the house, buried to the terrace and pops up just above paverstone surface. At that elbow- Flex liquid tight to and through the abs or whatever base at the tub continuing to the 'brain box' inside the panel. The flex conduit is about a 30 inch run total. It's evident the s/s brain box is designed to be used with conduit connections, and all made very convenient.

Bachman,
I did mine similar to yours my seal-tite runs thru the pump area and I put a fitting with a electrical nut into what I figured was the electrical box inside the tub. I was a bit disappointed with this plastic box and lid as it was very thin and I put the nut on backwards with fear if done the other way the teeth on the nut would cut thru the box.

The cabinet itself I would not conceder an electrical enclosure as it is made from wood etc. even though I feel it is just as safe doing it that way as the plastic box provided. I have seen lots of them where the wires are just stuck thru the hole.

I had an electrician I trusted so everything was to his liking, ideas or standards. I take no credit in any part of it aside from my estimate on where the conduit comes up - About 10" off from the corner of the tub …. Doh !!!!  :o
I even apologized to my friend / electrician since I felt it made him look bad. He just laughed. I'll put something ornamental at the sides of the tub or endcap the steps as I see often for landscape aesthetics or curb appeal. Now when I see all the nice beautified tubs, I think of all the mistakes they might be hiding !!   ;D

I can picture your dilemma with the box not being as secure as a metal one. The flex conduit in mine came up and had to curl back around as a U-turn so we were happy to have just enough room in here to do so without any extra stress or pull at the junction. It ended up fitting snug against some plumbing.

Flipping that toothed washer was a smart move. I don't believe these things typically vibrate or rattle as much as I might have guessed but those little details 'we' think of sometimes offer peace of mind if not insurance.

After reading a lot of posts by electricians experience on the high likelihood of missing the mark on where the conduit comes up I planned, checked, double checked and triple checked my mark.  Even after that the electrician had the conduit off by 8" and we had to move it yet again before pouring the concrete pad. Thankfully we hit the right spot.  This is a classic case of measure twice cut once.
