What would be the best possible way to put a sub panel in a detached garage. All wiring will be in 1 1/2" PVC. Ground at gargage. I know no service cable buried in conduit. Should i J-box and change over. It has been along time since I have done one. Thanks.
I would just do the PVC stubbed up, wall to wall, LB through the walls and you only end up with 2 90s so pulling is easy. Pull in 4 appropriately sized THHN/THWN and be happy. With 4 you are not regrounding the neutral at the garage. Drive a rod and ground the garage EGC bus.
