Ok, I want to fire my new unisaw up, but one big problem, no 220 outlet in the shop. For the time until I get one installed can I use my dryer outlet? My dryer outlet has the big 3 prong plug my saw has a small 3 prong plug with both flat blades facing the same way and the third being round. What is the easiest short term fix for this? An electrician I am not…

If it were me I would run a wire from the junction box (circuit breaker box) inserted into the same holes the wires to the drier are inserted into to a temporary outlet fastened near where I have the saw. Make sure you ground it. Just don’t let your wife run the drier at the same time.

Make sure your outlet is the same configuration as your plug.

But, I am not an electrician and I’m not living in your house..

simplest short term or long term really is to make an extension cord, put what ever plug ya need on the apporite end, not my idea though , its how a buddy of mine has run his saw for years

Safest course of action would be to rewire the motor for 115VAC for the time being.

If you are going to make up a cord, the slanted prongs on the dryer are the hots. Use 10-2 cable with ground. The bare is ground and the black and white will be the hots in the cord. The dryer plug you get may have a white colored screw for the center ground prong. The one that fits your saw should be green. those are the bare ground wire. The hots should have brass or darker colored screws where they go. Remember the ground is the most important part of this operation!! If you hook it to the panel, the grond goes where the bares and whites are. good luck.

Just get a “male” plug that matches your dryer outlet and install it on your saw cord. Make sure you transfer the hots and ground correctly. The blades are the hots and the round contact is the ground. Doesn’t matter which way the hots are connected, your saw won’t run backwards if you swap them. I believe your dryer will have three blades with the center blade being ground. Check the dryer outlet with a meter to make sure since some non-electricians don’t pay attention to correctly wiring 220-volt plugs. You should see 220 between the hots and 110 between hot and ground.

Joe:
I recently purchased a GO691 from Grizzly, which I have been happy with. It has a 3hp 220 motor. I have it in my garage (detached) which did not have 220. We had purchased a gas dryer so I fished a wire (#8-2) through the breeze way to our laundry room. I put a junction box on to a joist and made a splice. I put a sub-panel in my garage with a 40 amp breaker (main) and installed a 20amp for my saw. It worked out pretty good. I know MarkwithaK said to rewire the motor for 115. That would be good if the motor on your saw allows you to.

Good Luck

I run electric in my house and shop all of the time. I run it proper and don’t overload my circuits.

But outside of that, I hire an electrician for my jobs and one of the best people that I have noted on LJ for electrical advice is TopamaxSurvivor.

get an electrician, you could fry yourself or the motor, it just ain’t worth it. But if you choose not to wait have someone film it for u-tube. seriously electricity can kill or at least bite really bad. if the plug you have on now is two flats facing the same way and a ground then the motor is probably wired for 115 volts. have you tried to plug it in??

If you go with what TopamaxSurvivor said you should be ok.
I have 35 years of electrical work too.

Thanks for the vote of confidence guys :-)) Yup, I’m the real deal, master electrician going into year number 42. I would advise against trying 120 volts for 3 hp. It draws about 34 amps and takes a 70 amp breaker to start it. It will dim the lights for the whole neighborhood :-)) Everyone on the same transformer.

Hope they listen to you TopamaxSurvivor I know that you are right.

Lot of things you can play with but electricity if you don’t know too much don’t play with it may kill you.
