Hey guys I have a G1023ZX 5 HP 10’’ tablesaw that runs off 220 and I am looking to get away from just a shop vac alone and wanting to upgrade to a 2HP dust collector and have only 1 220 outlet on the wall and was wondering if I could plug a dust collector into the same outlet as the tablesaw or do I have to have a separate plug for each machine. These would be the only machines that I have that run off 220. The dust collector I am looking to purchase is on sale right now and its a Grizzly 2hp G0548zp and is it a good purchase? Thanks for the information greatly appreciated.

you can rearrange your breaker box with some piggy back work and make room for another 25 amp or 220 breaker and then run 2 machines at once I don’t think I would run 2 machines off 1 breaker

thats what I done to my break box it would be safer of course startup is where you draw the most power with seperate breakers you dont have to worry with overload but I am not an electricical eng. but that would be logical to me course I never went to college nor did i take pencil or paper to school for 5 years I fix things the way i want

From http://www.engineeringtoolbox.com/elctrical-motor-full-load-current-d_1499.html

Your 5 hp motor will draw 28 amps

2hp dust collector will draw 12 amps

What size breaker do you have?

The figures above are full-load (continuous duty) numbers. Keep in mind that a motor starting-up will draw much more until its up to speed. I’d seek professional advice from an electrician. Some of the worries I would have include the size and length of the wires to your outlet.

I have my 220 Grizz DC on its own circuit breaker; everything else has to take its turn on the other breaker. I think it’s wise to separate them, as 5 hp. draws a lot of amps.

all the electrician is goin to do is charge a bunch of money to piggy back some 15 amp breakers and put in a extra breaker this is very easy to do yourself the breakers just snap in you hook up the ground and the hot and thats it of course kill the power 1st

I’m running a 3hp TS and a 2hp DC on the same 220v line without issue, but a 5hp TS motor would be too much on my circuit. Depending on the wire and the breaker, you’re probably either going to have to run a separate 220v line for the DC, or get a DC that’ll run on 110v.

You will be way better off with 2 circuits, I would do everything possible to get set up that way.

Typically we need to run the circuit from the panel off one large breaker, say a 50 amp 220 volt breaker to a sub-panel. Then put two 20 amp 220 volt circuit breakers. Of course you need to adjust your amperage and wire sizes according to your needs. Keep in mind that besides the draw of your machines there is current loss due to distance.

So trying to run two machines off the same breaker could be a problem if there is a distance issue to the breaker panel; you start both at the same time or you put additional load on both. The sub-panel design will allow one machine to “pop” the breaker while the other continues running. Two machines on one breaker, both machines go down when the breaker pops.

Well I think you guys made up my mind and I was leaning towards just putting in another breaker. This will not be are hard task once I get my son to crawl in the crawl space to run the wire which he is not to fond of but that’s what they are for lol. Thanks for all the information guys and I cant wait until I can get some real dust collection in my shop.
