Belled end up or down

[jamessullivan8]

I hope this is easy for everyone because I can not find it any where

Does the NEC have a requirement for what way the belled end of a PVC 90 should be installed. I would like to know if any standard is out there NEMA ect...

Any way you like.

Welcome to the forum.

I personally like to put the bell end down. Saves on glue and still keeps the raceway dry.

Saves on glue

How does that work?

I looked and looked for the NEC rule. I got a real old inspector in cincinnati
they use a company called the IBI for inspection. The old inspector said it was up side down. I said if it had no bell at all the coupling would make the same joint....
No answer from him?

It was a poor attempt at humor. Sorry.

Bell down. Just my preference. No reason other than looks.

Maybe, just maybe, in northern climes there might be a case made for bell down to prevent water infiltrating the joint and breaking it up with freeze/thaw cycles.

is no rule but i would put it down just to help keep it dry. Way to deal with old inspectors is ask for the code number. He will just sign you off.

For aesthetics, I'll install bell-end down.

More importantly, I consider bell-end direction orientation as it pertains to wire pulling. I want to be pulling where my head enters the bell end of the conduit.

I would agree.
On a directly related note if the bell (or stationary) section of a vertical expansion joint is not installed with the barrel down, they will definitely allow water intrusion which will bust the joint if exposed to freezing temperatures.
