I am upgrading my main panel, it is currently located outside, I replaced the meter can and installed a GE exterior load center.
I've wired up a panel before, but never dealt with an exterior panel. I can't seem to find much information on how to bring the NM cable from inside into the panel.
Most obvious choice would be conduit to a J-box, but from my understanding, if the conduit is longer than 24" then you would have to derate the wires, which would make that option completely not possible.
To do this I would come out the side of my panel, and would have to use a 6"-8" piece of conduit that is slightly bent into a LB through the wall. It would then go into the back of a J-box in my crawlspace. This run would be really close to being 24" long, and may even be longer than 24".
Another option I've seen is a nipple ran out the back of the panel into the interior wall, the NM cable is ran through the nipple into the panel. I know this is a code violation though since code states NM must be secured at the panel.
Thoughts?
