Let's say I have a 200 amp breaker panel that is flush mount. I want to wire in an EVSE across the garage using conduit. Somehow I need to make that transition for the conduit from behind the drywall to conduit on the surface of the drywall. I believe a junction box is the right way to do this. The obvious solution is a surface mount junction box and have conduit enter it from the back, turn in the box, and come out the side to continue on the rest of the way.
I'm wondering, can I get a deep (> 6") junction box and have it partially in the wall and partially exposed so that the conduit from the panel could come in through the top of the box on the back half and exit out the side on the front half? I would probably mount the box to the wall stud on the side of the box.
---- | | | | breaker panel | | ---- | | conduit behind drywall | --- | | junction box | |------------------- <- conduit on surface of drywall to EVSE ---
Can a conduit body be used in this way instead of a junction box (assuming a sweep elbow fits in the stud space to change from down to out)?
It's a 2"x6" exterior wall. Will be using PVC schedule 80 conduit on the exposed run.
