I am planning on running electrical service out to a newly constructed shed this spring and I wanted to post my plan on this forum to get feedback prior to beginning the work. I will just be using normal DIY hand tools, nothing heavy duty, i.e. welding equipment. The plan: Install a double pole 20 amp breaker at my main panel. The shed is about 50’ from the main panel. I am planning running 12/3 UF-B wire from the main panel to the shed, but I don’t like the idea of not having it a conduit even though it is rated for direct burial, plus I would only have to dig down to 18” (maybe 12”?) as opposed to 24” if it were in a conduit. I guess one question I want to pose would be is there any issue with running UF-B inside PVC conduit? It seems like I’ve seen conflicting info on this. I was planning on using 3/4" conduit, is this a good size for 12/3 UF-B? Once I am at the shed I will run to a double pole 20 amp disconnect switch where I will split off one circuit for lights & one for the outlets using 12/2 NM-B. I plan on installing a 20 amp GFCI outlet at the first outlet. I am guessing that some will suggest upsizing to 10 gauge wires because of the distance from the panel and I am considering it. If money isn’t tight this spring I’ll probably do it anyway but just in case I don’t I wanted to know if I would really be losing that much with the 12 gauge wire. Any suggestions / Comments? Thanks in advance!
