Wiring a garage. How does this look?


Day late and a dollar short.... I noticed #6, 78, and 80 cable needing a running board between trusses and secured every 4-1/2' also. #59, left top of panel box- knock-out removed? Needs a plug or my eyes need testing, lol. Next to the knife pointy end...
Be safe, G

Could you please provide a code article that would override 334.10(3)? Basements would not be covered by (3) as they are not "other structures".

(Poster #1) No. It does NOT look funny. Most Panels are designed to be mounted in either VERTICAL direction! What's important is that the Main breaker should be on top. What I meant to say is that where there is no Main Breaker in the Panel, there's no difference which way you hang it up!

Please provide a compelling reason of why the main breaker should be at the top, besides the feed coming into the top.

That's a good looking DIY electrical job. The only issues you may have are securing the cables a little better. The main issue with NM is to guard against the potential for physical damage. And that is also why running exposed NM in a basement is different from open wiring in a garage because the potential to damage the cable in the garage is greater than in the basement.

I run all my garage/shed etc runs inside the stud bay
But I've yet to see a shed/barn/unfinished garage/detached structure anywhere around here or other areas I've been where there is a "15 minute finish rating"

And the most compelling reason for having the Main breaker at the top is for instant identification
I have a sub panel that has another 240v load off of it
The panel is fed from the bottom
If I had reversed the panel then the Main breaker would be at the bottom
The 240v load - breaker at the top- would then lead to confusion if the3 panel needed to be shut down quickly by someone not familiar with the setup

That's why panels include a label that says "Main".
Main up or main down doesn't matter, as long as the breaker on-off is a side-to-side motion.

I mounted it upside down and the breaker is indeed at the bottom left. I really dont like that fact but the panel instructions said to do it that way so I did.

Will the inspector have a problem with this?

I have never worked with drywall and I think I could hang it, but dont think I can mudd/tape it. Is osb not ok to use? I wonder how drywall would look if it were not taped, mudded? I also am not sure how the corners fit toghter.

What I liked about osb, is I could paint each sheet, put it up one at a time by screwing it in. If I needed to get behind the wall to wire a new circuit or something, I could just unscrew the osb.

I never installed drywall myself until I did a renovation here at home a few years back. I did okay, but I had been watching drywallers for many years on job sites and just kinda did it the way they did. If I had never seen it being installed so many times, it may not have turned out so good. OSB is fine. So is plywood or paneling. Do whatever you want. Do not put up any walls until the first (rough) inspection is over.

Don't be concerned about the position of the panel. Use the label that came with it that say's "MAIN". As long as the breaker handle is in the up position or either side position when the breaker is closed you are okay. If the breaker handle had to be pushed down to close it, then you would have a problem.

But the most compelling reason for keeping the Main Breaker on top (and not take into consideration where the feed is coming from) is that no matter where it's coming from you can always put it on top!

What do you guys think about putting all wiring in conduit for an outbuilding like this? The place I bought has a similar metal building garage/shop that has all wiring in conduit. It is about impossible to keep mice out of these metal building shops so I feel better knowing they won't be chewing on any wires.

Or do mice not chew on wires?

Mice will chew on wires, conduit can be a good idea for this reason
One person said the insulation had been stripped by mice from his wires - leaving bare wire

My shed has had mice for years before we bought the house
Not a single chewed wire

In the future, if you ever plan on anything else. Be careful about stapling wires on the top horizontal plate making them difficult to see from ground level. I learned the hard way when I was a green electrician. I stapled a bundle of wires down in a bathroom and the plumber drilled a well placed 2.5" hole saw right through all of them. Didn't know until the trim out and nothing worked. Luckily it was in an attic, but, it was summer.

It is a big pet pieve of mine when the feed comes into the bottom of the panel and the installer put the main breaker at the top. The main feeders take up sooo much gutter space. Maybe not a big deal in a small subpanel, but any panel 100 A and larger it can be a pain.
