Since I can't use NM-B 6/2 cable to install my wall connector at full load (48A continuous / 60A breaker), which would have made life simple, i'm now considering to run PVC conduit with THHN wires (6 for the hots, 10 for ground). The distance between panel is only about 15 feet. The problem, however, is how to transition between the PVC conduit that runs down inside the wall (normal 2x4 wall) to the actual charger? I'd like to avoid having the conduit visible, so I essentially have to have a 90 degree connection inside the wall -- obviously the usual sweeping elbows won't fit. A LB-type conduit connector doesn't appear to be a code-compliant option, either, since it needs to be accessible, ie., can't be buried in the wall.
So my current plan is to put a junction box into the wall, hopefully I can find a fitting cover plate that i drill a hole through to route the wires into the wall connector. I'd just mount the wall connector on top of the junction box, so the box itself would be hidden, but still accessible (I believe). Does that sound like a reasonable plan, or are there any other options that I've missed?
Also, it sounds like 3/4" conduit should be fine for the 3 wires, but if anyone has made the experience that pulling the wires through that is not fun, I'd be interested to know, since upgrading to 1" conduit is of course an option, too.
