Running UF cable through metal or PVC conduit. Although not commonly done, it is allowable to run UF cable (but NOT NM) cable through metal or PVC conduit in an underground application. Most electricians prefer to fish individual waterproof THWN conductors through conduit, simply because it is easier.
Can you use 6’3 conduit wire?
A 6/3 wire can fit a ¾ conduit. But the number of cables you can fit in the conduit will depend on the type of conduit. For instance, a ¾-inch PVC Sch 40 conduit can accommodate 21 14AWG wires and 15 12AWG wires. On the other hand, a ¾-inch PVC Sch 80 conduit can accommodate 17 14AWG wire and 12 12AWG wire.

Is MHF direct burial?
Although MHF is suitable for direct burial, it must be installed in conduit for physical protection where it enters and emerges from the soil.
Can mobile home feeder be used indoors?
USE-2/RHH-2/RHW-2 can be direct buried, but otherwise requires a raceway. This, practically, limits single-rated USE-2 wires and cables to direct burial applications, or use as a multiplex cable-in-conduit outdoors. (You can’t use it indoors or for general aboveground work, even when in a raceway!)Jun 2, 2019.
