Walls off - Extra Garage Electrical?

[HamAndEggs]

I now have 200a service in my garage with a nice big panel

I already have 2 lighting circuits and 3 x 20a receptacle circuits (One for each wall), 1 for garage door opener and 1 for networking equipment

I plan on adding 2 circuits for electric car charging

Other than all of the above, what should I add in? Running wire right now is trivial. I am into light woodworking, have never welded (But might want to one day)

What makes sense to add in? Any ideas welcomed!

conduit to the far side with a pull string if you're really worried.

Not sure what your size is, but I would have 20a receptacles every few feet. At a minimum, I would want a 30a 220 for a table saw and a 50a for welder.

Trivial for me too so I didn't.

I run what I need when I need it... surface conduit.

You don't say what size the space is. A receptacle every 6 or 8 feet is plenty IMHO. I alternated which circuit they are on so I can fully load adjacent ones without tripping a breaker. I also put a 3/4 conduit up into the ceiling and to the middle of three walls with a 4 x 4 deep box and dual gang mud ring so I can put in whatever I need later.

I agree with the 6-8 foot spacing per wall & 1 in each wall shorter than that. (1 on each side of oh door). If you will have a workbench, put a double duplex above its location. Add exterior recepts where convenient. Did you use gfci breakers? If not, use a feed thru recept as first on each wall circuit. After you decide how you'll use the space, add 220v recepts for compressor, saws, welders, or ?

In my new 24x28 detached garage/shop build I installed duplex outlets every four feet on three walls. On the west wall (where most of the equipment will be) I have two circuits of 20 amp outlets. The other walls have two circuits of 15 amp outlets. So I certainly have enough outlets. Perhaps every six feet would have been enough, but every eight feet would have been too few spacing.

Plan for future growth; empty conduits with pull strings are cheap insurance.

I say 1" conduit thru both walls, so if you ever need to change something you can change it.

On my shop, I love these Siemens Talon sub-panels. They come with 3 breakers, 3 outlets: 50A 240v, 30A 120v, 20A 120V GFCI. They are very flexible and for $150, they're a great value.. can be mounted outdoors if you want.

Don't forget ceiling outlets for any machines you may want to mount up there, like air filtration, or for cord reels/drops for equipment placed out in floor of garage. If you want ceiling fan(s) or outlets up high for a tv or any signs etc.

For woodworking your AC needs will depend on the size of the equipment you want. For example, my contractors table saw is 1 HP so 120 is fine, but my Unisaw is 3 HP and 240 only. My soon to be replaced 14” bandsaw is 120V, but the new 17” is 240V as well.

For my needs, I need 3 240V outlets - 1 for the unisaw, 1 for the dust collector, and one for the band saw. If I ever upgrade my jointer or planer I’ll need more...

I agree that outlets every 6 feet or so are fine, but around a bench I’d do more. Also ceiling outlets for a dust filter setup, garage door openers, and a reel extension cord as well. Lots of people like garage outlets a bit over 4 foot high so you can put drywall or plywood on its side and not block them.
