Has anyone else run into problems using schedule 40 LBs with schedule 80 pvc? We had an inspector make us take them out and use metal LBs. I don't agree with that one. Anyone with code references?

Inspector only said the fittings weren't schedule 80 and the had to be replaced. I agree schedule 80 pipe is required. But aren't the fittings dual rated?

:blink::blink:

I'd ask him to produce a link or part number to a "schedule 80" LB.

Talk to his superior before redoing your work.

i've used a fair bit of schedule 80 in place
of GRC, and schedule 40 couplings were
all that i used. checke with the AHJ, and
he was fine with it, as well.

and if you had to have schedule 80 fittings,
just try and find a schedule 80 bellmouth to
enter an underground substructure.

now, as schedule 80 pvc in a lot of areas is
permitted instead of GRC, he might be going
down the road requesting you use condulets
that are suitable in GRC runs. which would
be a malleable iron fitting.

play it safe. rip it out and replace with OCAL.
:p

Of all the fittings that could have a schedule 80 version, the bell end is the one I'd like to see THE MOST.

A schedule 80 coupling, thread adapter, weatherhead, or conduit body, I don't really see the concern, and I'd prefer to see a dual listing on the datasheets for use with both PVC schedule ratings, to put this question to rest. The extra thickness of the conduit makes no difference. The wire doesn't really interact directly with the edge of the conduit in these fittings. But the bell end, specifically built to round the edge of a conduit opening, doesn't really help with a schedule 80 conduit.
 
Is there such a thing as schedule 80 (in electrical listed) fittings? All I have ever seen is factory elbows in sch 80, but never any choice on other fittings. Heavier duty couplings and male adapters would be nice sometimes.

I know they make 80 couplings, not sure about fa's and ma's. What are nice too, but hard to find in Stock are the "long line" couplings. Much more surface area for a better bond. Good for where you know you'll be rutting on the pipe, have a bend/misalignment, etc.

I often wondered if there was a long coupling. Bell ends already on the pipe are hard to beat, especially for underground applications, but problem is there is only one bell end per 10 foot length.
 
This is what T&B says:

Q.The PVC conduit bodies in the catalog do not state if they are for use on Sch40 or Sch80.

A.All the PVC fittings such as the conduit bodies, male adapters, female adapter, couplings, etc. are neither Schedule 40 nor Schedule 80 themselves. However, they are UL listed and designed to be used with both Schedule 40 and Schedule 80 conduit.

Next time I'm at the supply house and theres a new guy, I'm going to ask him for a sched 80 LB ;)
