I'm wiring a shed with a subpanel approx 150' from the main in the house. I'll be using 8-3 w/ grnd on 30amp breakers, 100amp main lug in the shed with 30amp as main disconnect back-feeding the panel. I'll be running a #6 ground to the ground rod and keeping the neutral isolated at the subpanel (bonded at the main service entrance).
Note: the contractor put a 3/4" pvc stub in the slab when building the shed so that is what I have to work with.
My first thought was to run 8-3 NM w/ grnd from the main panel overhead in the house out to the porch, go down the wall in a 3/4" pvc to a bell box, splice with #8 THHN underground in a 3/4" pvc into the ALREADY IN PLACE 3/4" stub that was put in the slab as mentioned before.
My question is this: Would it be an option to just run 8-3 w/ grnd UF from the main service all the way out to the shed and up through the 3/4" stub and avoid the splice.
a. Will the 8-3 w/ ground UF fit through the 1.5' 3/4" pvc stub?
b. Does the code allow you to use UF from the main service in this way? or do I need a green insulated equipment grounding conductor from the main to the sub?
Thanks for your help in advance and any other recommendations are welcomed. I was a commercial electrician for a few years but am not a residential expert by any means.
