I have three 10/2 UF-B cables on an exterior wall that I'd like to route to my interior load center on the other side of the wall. I intend to bring the UF-B cables into the interior wall cavity and then into the bottom of the load center.
The photo shows the UF-B cables (please ignore the one temporarily Jerry-rigged for use with an extension cord) as well as a ground wire that is connected to an ufer ground. The conduits are used only for physical protection and encased in concrete below (the UF-B is buried without a conduit). The 1-1/4 PVC conduit is sch-80 and the 3/4 conduit for the ground is sch-40. The bottom of the interior load center is just above the abandoned telephone service conduit.
I can think of two options:
1) Install two LB conduit bodies. Optionally, I could enlarge the hole from the abandoned telephone service conduit for the three UF-B cables instead of drilling a new hole. This would require installing a 90 on the 1-1/4 conduit.
2) Install a 6x6x4 PVC junction box and connect both the 1-1/4 conduit and 3/4 conduit on the bottom side. Then install a conduit from the back of the box to the interior wall cavity.
I also believe that I should install two expansion couplings for the exterior conduits. This will shortening the 1-1/4 conduit which will be a pain because the wires are inside and the conduit is too tight against the wall to use a PVC tubing cutter.
Would you chose option 1, 2, or something else? Any advice is appreciated!
