hi,
ok how about this...an fs box is mounted on an exterior wall of a single family dwelling...once the cable enters the fs box it is stripped and then the conductors are run in a pvc conduit to a shed...120VAC...

where is the problem?

how about a sub panel in a attached garage with a 2" piece of pvc sch 40 extended into the cieling, filled with several 12/2, 12/3, 3C/6?

is this legal?

-regards
