Hopefully its not nm going to the bldg.

Id probably run rmc from the house if theres a panel in the garage. Use the rmc as the egc plus a suplemental gec for the panel.
If its a single or mwbc Id. run uf

Go all out and then some if it is a feeder, but if it is just a MWBC you settle for unprotected UF? Is that what you are saying?

Other than some extra breakers and driving a ground rod at the garage for a feeder what is the difference between the one or the other?
 
I meant if it has a panel then run thwn and Rmc . If it has a mwbc at most then use uf because nm isnt for wet locations

Must be hard digging in your area. Here we would just run the feeder in PVC.

I have run RMC when I had to replace UF that was only buried about 6" and had been damaged and the reason they didn't go any deeper was it was solid rock. I guess the reason I like PVC is it's cheap to go a size bigger than needed.

Gotcha. Nothing wrong with RMC, but I agree with growler, the only way I'm running it is if I can't get through some rocks. That has been the case for me since I live in the Rockies. I use PVC every I can though.
 
If the home owner isnt sure whats gonna happen. Pipe it . leave the conductors out , call for wall rough and decide later whats best

What's the point in leaving the wire out? If you run the pipe for rough inspection, I'd say you're committed to the wiring method.

Exactly Smart$, Here an inspection at this stage would get a ReInspect notice because you are not ready. The AHJ wants to see boxes (1900 or Nail on plastic/fiberglass), wires pulled & made up etc etc. Otherwise there is nothing to inspect.
 
I wasnt aware a wall rough inspection required ungtounded and grounded conductors.
I have passed with strapping and a grounding method.
Maybe my intention is that a wall that is not going to be covered has no inspection requirements til the final.

Im probably wrong. I thought ent was listed for finished ceiling s and areas that were inaccessible as well as concrete slabs.

Back when unfinished garages were more common here in the People's Republic then they are now, the way it was handled was to run everything above & drop down where ever a switch or receptacle was desired, then just the stud bay that had NM in it was covered in drywall, the wiring was minimal with few receptacles & ugly but the wiring was protected.
 
"detached storage garage" - is this a shed or a garage? here below 150'sq wouldnt require a permit at all. I'm trying to remember the last unfinished garage I saw... can't remember. I would be okay with NM ran down the studs to boxes and horizontal runs thru or above the joists, but I'm not an inspector.. and I have seen junk laid across cables above or inbetween joists, so.. (take that with a grain of salt the size of RI).
