Did a church kitchen years ago. I warned the woman in charge, one roaster per duplex. It has worked all of 15 years or better. She is getting older and when she is gone, I'll bet dollars to donuts, they start tripping breakers.
Offer to replace them with single receptacles (now).
 
Hey guys first time posting .. wish I knew about this forum years ago .. have this exact dilemma .. bid a 12k sq ft home over here in Brentwood CA with my old prices (before the copper spike) and won the job of course I did lol. Now I’m sweating it big time .. going to run 14 everywhere.. I normally just go 14 on LT crkts and smokes .. looks like the kitchen and laundry will be the only 12 I’ll be running .. super worried. 12k sq ft spec home for $120k .. help !! also trying to attack a lot of the longer runs with pvc in the footings and slab.. feel like I will save a lot of time and money (drilling wood and straps snd nail plates) if I do that.. please tell me I’ll be ok

They can get away with two per 20A circuit as long as they’re not cranked all the way up. They’ll cycle enough to not trip.
 
Here in NYC it's a requirement #12 minimum $14 I'd not allowed even for EGCs

#12 for bath gfci also.
And depending on code cycle, #12 for some garage receps.

For what it's worth, I don't think a residential Sparky is all that efficient running under slabs and then tying it in later. Do what you do best. Drill it out and pull it in Romex.

I wired 8000+ sf custom and semi-custom homes for several years. I'm guessing a 12,000 sf spec home, you'll probably have 16,000 feet of wire.

That means you will probably spend $5,000 more than you anticipated. But honestly, I would think if you are at $10 per square foot on a spec home you are probably okay.

Thanks! Appreciate It. I’ve actually done a couple large spec homes in the past with Lots of pvc in the underground / footing.. as long as you have good prints / drawings it cuts a ton of time and materials out .. no strapping, nail plates , less drilling etc etc ..I used to do a lot of custom restaurants / TI work and would do tons of underground. Shouldn’t any electrician who is worth his salt be efficient at running underground pvc??

Now I get it. Doing restaurant work in the past, you for sure have a handle on underground pvc.

I think most residential guys don't do it enough to be efficient at it. I know I don't. My efficiency is at its highest when I'm doing the same things in the same way. That means drilling and pulling Romex 👍👍

It's kind of like doing plumbing. It can be done, but might require a half dozen trips to the hardware store to have everything you need. And having to think through a lot more.

If you would, take some pics along the way and post some here
 
Well speaking of plumbing, and I was one, running under the slab is a huge time and material saver.

With plumbing the downside is if an underground line is defective. With electrical you just pull the old out and the new in.

Question if I may. Is it required to drill when wiring is in the attic? How about if it is run in EMT? Can I have unistrut hung from threaded rod and all my EMT run on that? Or just add collar ties to rafters and strap EMT to that? House is single story, slab on grade, hand cut rafters.
