An inspector told me I could not reduce the size of conduit in a run except at the termination. The contractor ran a 2" PVC underground. At grade level I installed a Female Adaptor and a 2"x1" reducing bushing. I then ran 1" sealtight to a small panel in a piece of equipment. The circuit was 3 #8, 1#10 Grd. The total length of the entire run was only about 12'. He said "It's somewhere in the code book". Can someone save me a hassle and let me know where to find that one? Thanks
Try my classic response: "Thanks for pointing that out. When you get back to the office would you call me and tell me the code section so I can read up on it. I'd hate to get caught in the same mistake twice."
It usually works; plus he's at the other end of the phone now and it's easier for him to say he'll let it go when he's not face to face.
I just got back from an out of town job (3 days). I got called on one thing. No plastic bushings on 3" PVC Terminal adaptors. The contractor oversized the underground conduit from plan specs from 2" to 3". The pull was 2 #1 and 1#8 Grd. So as you can can imagine there are three dinkey little wires coming out of a huge conduit, not even touching the edges. The inspector made me tear everything apart to install bushings. I believe in bell ends for feeding but do you always use bushings on PVC and is this a fair call?

I rarely use PVC/RNC, and dare I say don't often use bushings on it either, because often the only times I use it, it will have Bell End, and a steel conduit on the other. But yep, required.
352.46 Bushings. Where a conduit enters a box, fitting, or other enclosure, a bushing or adapter shall be provided to protect the wire from abrasion unless the box, fitting, or enclosure design provides equivalent protection.
