I am putting the overhead service for my house underground and I am getting ready to trench and assemble the conduit. Since my old service panel is a top entry, flush mount box with the meter at the top, it looks like I need to get a new service panel with service entry at the bottom.
I am required to use 2" pvc conduit with 36" sweeps. All elbows have to be 36" radius. I believe this includes any offsets I may add. Flexi-conduit is not allowed. One mystery is how I mate the conduit with the new flush mount panel. I expect the conduit will come up just outside the wall, then it will transition thru the siding between the joists and just under the box itself. This requires an offset of around 3 or 4" but no more than 36" radius.
Are such conduit offsets available?
Is bending a conduit (with a heat gun or other) allowed?
Are flexible rubber couplings like that used on plumbing ever used on electrical conduit?
This 2" stuff is very rigid. If I use a threaded male adaptor to attach to the box, I'd have to attach it before I buried the conduit or install the box after the conduit was in place, otherwise I'd never be able to bend the stuff enough to insert the threaded end. The other method would be to use a threaded female adaptor and thread in a nipple from inside the box. Is there a completely different method/coupling I am unaware of?
