Adding Box Adaptor to a PVC Conduit Body
I need a 3" PVC conduit body that is a combination LB and LL style. No one makes one like that. Before I order a couple of 3" LB style conduit bodies (which are not cheap) and a couple of box adaptors, I would like to know if a 3" box adapter (i.e., 3" round slip adapter that is glued into a junction box to connect the box to conduit) can be installed in the side of a 3" LB style conduit body. If you have done that successfully, I'd love to know.
Thanks.
Thanks.

Are you trying to add another opening to the LB so that it can take 3 conduits? If so, that's probably not code compliant.
Would an 8 x 8 or 10 x 10 box with three adapters do what you're looking for?

Adding an additional port to the LB would not meet the bend radius requirements of the electrical code. A junction box would be needed.

I have three 1/0 conductors (plus a smaller EGC) exiting 3" conduit just below ground level in a pull box. I want to tap into them. Instead of doing a tap splice in the pull box, I am installing an above ground panel with terminal blocks to connect everything (12 conductors in all, counting the EGCs). Because the pull box is in a location that becomes inundated on rare occasions, I want the seal off the the conduit ends in the pull box while still providing access for future cable pulling.
I am planning to use junction boxes, but the only water tight (NEMA 6 rated??) non-metalic boxes I can find are square, which doesn't allow me to maximize the space I have to work with in the pull box. By uitilizing an enclosure on one conduit that is significantly longer than it is wide, I can use larger square boxes on the other two conduit ends.
I can't seem to find NEMA ratings for conduit bodies. Are they water tight, or just resistant to splash, like NEMA 4 rated enclosures? If it's the latter, then I can find rectangular junction boxes that are NEMA 4 rated, which would allow me the maximize the pull box space. If conduit bodies are water tight though, I'd like to use one, if possible.
How would the bend radius on a LB conduit body with a side adapter added be any different than the bend radius of a LL or LR conduit body? If a 3" conduit body is oversized to begin with, why couldn't the added side adapter yield a bending radius that meets code?
Thanks!!

The bend radius would need to be measured across the width. As designed the radius is measured along the length.
