Part II - Michaels PVC supporting Pool JB

[iwire]

I think it is a tough call for AHJ's with that kind of wording. wonder if UL offers any ideas?

I think it is a very easy call, the box cannot be supported by PVC, options include securing the box itself or switching to RMC or IMC at the box.

I think this really comes down to one of those times where something is a very common practice, it was how we were taught and later we find it is not really right.

I know I have number of those myself.

I use the following box for my pool lights...


Along with a jbox support rod, which is a 3/4"x5' pvc rod.... Sorry I couldn't find a pic of the rod.

You guys just need to find the right material to do the job right.

You mean, the box cannot be supported by a pvc raceway.

Obviously since that box is supported with pvc-- How do you drive an 8' pvc rod?

Dennis, you can't support the box by a pvc RACEWAY, thats the only violation. I buy the 5' rods, they drive in like any other rod.

I agreed but how do you drive the pvc rod

I agreed but how do you drive the pvc rod

I just use a hammer.

I just use a hammer.

Try to drive a 5 ft long 1/2 or 3/4 PVC rod around here with a hammer, you won't get very far.

Rock and or clay soil & your PVC would bend or break.

Here we would use rigid steel conduit or uni strut to support the box

With a PVC driver of course

I agree, sounds like this one has been falling through the cracks since we transitioned to PVC for pool lights. I wonder what the box manufacturers would say about this and the use of their products with only PVC.

Im sure they don't care since its not up to them to make sure people use their products as designed... The person installing the product should be looking into proper product usage and code enforcement should be updated... I seriously don't get at all why I have to take required code classes when nobody else is getting any smarter in the field.

I think they would say we were not using it as intended. I found only this schematic, but even though it is not for the actual j-box, it clearly shows that the conduit should be rigid.
