I'm wiring up my shop and plan to have 110 outlets every 5 feet on the walls. How many should I put on one circuit? I'm using 12 gauge wire.
Thanks
Dave

Yup, where do you live. In the US there is no limit for residential. That may not be the best practice though.

What do you plan for uses?

There is no limit in residential, in non-residential each one is counted as 180 VA each. One is pretty safe by limiting them to 10 receptacles max per circuit.

This is a residential detached garage in Shreveport, LA. I don't envision having multiple things running at once but am not sure where I'll end up years from now. The garage is for my retirement woodworking hobby.
Thanks,
Dave

Wire & breakers are relatively cheap compared to the aggravation experienced down the road when you don't have enough circuits & keep blowing them.
I would consider putting each wall on a separate circuit

I always ran no more than "one wall" per 110 circuit, lights on their own, and the big stuff on its own leg (sometimes necessary because of the 220 requirement). I used to have access to cheap or freebie electrical sstuff, so I could add as I wanted - one place (in Berkeley, years and years ago) I had what would look to a pro as a spaghetti factory... altho nothing ever burned (thank the Gods!) I knew it wasn't right...

I was told no more than 8 outlets per circuit running 12-2 on 20 amp circuits... so from then on I've tried to stick to it. The reasoning is you'll never have *all* of those outlets hot and drawing 100% at once. Lights are easier, as there's no variable - you know what those fixtures will draw, so you can go either 14 or 12, plan for 150% of their draw, and stay safe.

Hi Dave, Bistineau and I are your neighbors. I live at the end of Colquitt Rd. area, Bistineau..........Well you can guess where he lives.:beer:

Btw, I did walls on each ckt. and my 220's by themselves.

"Best Practice" in my local is no more than 8 per circuit to allow for expansion. I would recommend no more than 13 on a circuit with 12 wire.

Thanks all. I think I'm going one circuit per wall for the 110 and need to think on how to do the 220. And then how many 3-phase circuits to run. I have a mix of single and 3-phase tools run from a phase converter.

I presume you're going with 20 amp circuits for the outlets.

Consider putting in a double box and four outlets at each location. Don't forget the GFCI's on each circuit. Don't try to scrimp and use the cheap contractor outlets, get the better grade, you'll appreciate it in the long run.

When does the pig tail vs backstab vs backwire debate start?

I've only hooked up one phase converter and it was for a single unit, a mixer. Is there a max amp on yours,so say it's 60 amps you could power up a 60 amp 3 phase panel and then wire up the equipment like a normal hookup. I will tell you 3 phase stuff isn't cheap
