I’m in the last stages of tweaking the outlet locations in my new shop. I’ve decided that the machinery located in the center of the room will have an option for a ceiling drop to avoid too many cords running across the floor. The table saw is my biggest concern.

I have a Unisaw that I’ve never used as I’ve been purchasing items off Craigs for the last year in anticipation of this new haven for me. Prior to this my experience with a full size saw has been years ago and the cord ran across my father in-laws garage floor. So I’m a little unsure as to the best place to locate the 220 drop from that ceiling. Dust collector pipe too for that matter. Should I go to the left to the right the blade? Far right or left or somewhere in between?

I put mine (both the ducting and the power cord) at the end of the right extension. As it turns out that’s almost the exact center of the shop. This has worked out well for me.

I would go far right of the blade, ideally off the right side of the side extension table, that way it will never get in your way, regardless of how wide you’re trying to rip something.

Concrete or wood floor? In my concrete floor, I cut a 2” wide by 3” deep notch across the floor from the wall, (about an 8’ run) with a diamond blade and my circular saw and then ran conduit in it. I then ran 12-2 romex in the conduit and set a 220V box in the floor for the saw. I used concrete patch set everything in place. It all Worked great. Took about 4 hours but it was worth it not to have a cord hanging down. Runs off the same 30 amp circuit as my 8” jointer. They are Never on at the same time. If it’s a wood sub floor you could use a router to cut a groove and do basically the same thing.

Edit: or in the rare chance you run things left of the blade, more correctly: +10 the far side of the rail the fence is on the most. :)

TaybulSawz – “Runs off the same 30 amp circuit as my 8ā€ jointer. They are Never on at the same time.”

Good idea. I’m trying to cram as many “future 220” circuits into my panel right now and that just saved me one! I’m going to stay up on the ceiling and use twist locks so I guess I’ll still have two different boxes. Seems I could also do the same with the planer and a sander too.

+1 TaybulSawz I did the same thing and used self level in a caulking gun to seal the wire in.

The last thing I would want is a ceiling drop for my table saw ,it’s much better in the floor if you can do it. or run it from the wall and use a wire protector,like this one.

I’m not an electrician but I thought you were suppose to only have one 220 outlet on a circuit
I hope your shop comes together very well.

I tend to agree with jim rather than loading two wires into a breaker get the slimmer breaker they have them at home depot like this one.

They only take up the space of a standard single pole breaker so you can get a lot more space in your panel.

There’s absolutely no reason you can’t use multiple outlets on a 240V breaker. It’s no different than putting multiple outlets on a 120V breaker. For some tools though, you might want one that’s dedicated, like the DC.

Your right Fred you can run multiple outlets. If your gonna put two items that can draw more then the amperage limit of a breaker, like a tablesaw, you’re gonna have problems. Especially the startup draw on a motor. That will trip it every time.

you can hook up 50 220v machines to a single 220v outlet, no problem. just do not power on more than 1 at a time.

my bosch 4100 contractor saw is also doomed to be in the middle of my 2car garage workshop. luckily, i planned ahead and installed a 20amp circuit in the ceiling right above it with a 12guage retractable reel. tho i’m still thinking of getting some unistrut, dolley/gantry to ride in the unistrut channel, and have a sliding swivel boom to rotate another 20amp circuit (in mc cable) anywhere in a 10’ swing.

I’d sure like to see that!

I have ceiling drops in my shop and never use them. I was always catching long pieces of lumber on them. My cords are on the floor covered by anti-fatigue mats.
