can somebody tell me what the NEC says about the specifics of wiring a detached garage/workshop like type of outlets to use (gfci), outlet spaceing and distance from the floor, switch box distance from the floor, sub panel distance from the floor and how close to a door or window,wire over or under the outlet boxes and distance from box to wire either way, and distance between staples?
currently the wiring is lower than the boxes and I think maybe they are supposed to be like 12" above them?will I need nailer plates over each stud?
Im close to tearing it all out and just starting over because now I think I have it all wrong lol
thanks

like type of outlets to use (gfci),
All 125v 15 & 20a receptacles must be GFI protected.


outlet spaceing and distance from the floor, switch box distance from the floor,
No specific requirements.


sub panel distance from the floor and how close to a door or window,
Only that the highest breaker andle be no higher than 6' 7" from the floor.


wire over or under the outlet boxes and distance from box to wire either way, and distance between staples?
Nope. Only the standard stapling and securing rules. 12" from a box and 4.5' apart max.


currently the wiring is lower than the boxes and I think maybe they are supposed to be like 12" above them?
Nope.


will I need nailer plates over each stud?
Only if the holes are drilled closer than 1-1/4" from the edge of the stud.


All this is regular NEC stuff. Being a detached structure the physical installation is the same.

I suggest you get a couple of good books on home wiring. The NEC is not a good resource for a DIYer.

thanks scott I was just actually looking through that!!

thanks Speedy Petey, I actually have a Hd wiring 123 which is not a bad book for us newb's, just trying to get specific so there is noquestion later, I should probably have this all inspected so just preping for that making sure my work is good.
Would I be able to use one of those breaker box gfci's and would it go into the sub panel or the main panel? thanks

Keep in mind this is a structure and not a dwelling. What is required for dwellings is not always required in structures.

good poin I always just figured that since it is next to a dwelling for 1 and that it is a garage/shop that they would feel that it is importand to make sure proper and safe practice was used to install an electrical service, being that a lot of people dont mind hacking cords and plugs and abusing and outlet to use some heavier tools and equipment.
at the same time if you run your 220v dryer a couple loads a day and run your electric range plus lights tv's radio's water heater etc all day long then 5 miniutes of drilling and grinding and welding or what ever there is a big difference.
any ways it might not be an issue for my city which is good for me because I can just do it without all of the red tape, at least I know Im in compliance or will be with the NEC which gives me a safe feeling!:yes:
I will add some pic's when I get the box all wired up and finished

Do not get get me wrong. Structures are addressed in the NEC and must be compliant. When you add sleeping quarters then it becomes a dwelling. A dryer and range technically do make it a dwelling. The addition of a bedroom or sleeping area does.

Speedy Petey- Why would "All 125v 15 & 20a receptacles must be GFI protected", in a detached garage/workshop? "All this is regular NEC stuff." Sorry, but I've looked and looked and can't come up with any NEC that would dictate this. Please elaborate. Thanks, David

210.8(A)(2) The 05 has two exceptions, the 08 does not.

Edit:hpp58 already answered, did not see post.
