Ok my search for the perfect table saw just got some options. I just moved into house and there was n room in box to upgrade to 220 on garage line.

My wife was cleaning around drier and tells me there is a huge outlet behind it. I look and it is a 30AMP 220 dedicated line. The drier is mounted on wall behind garage. ALRIGHT!!!

Am I right in the theory that I can run any lower AMP saw on the 30AMP plug by changing the plug end. My understanding the different plugs are so nobody plugs in a higher AMP plug in a lower amp outlet. I am the only one here so it should be a non issue.

With a saw I know there is a high initial draw so what should I limit a saws AMP rating??

Thanks

Respectfully, I really think you should get a professional to help you with the electrical. It doesn’t sound like you have enough of an understanding of it to do your own work. Messing around with electrical systems without knowledge and experience causes fires all the time.

Most dryers use 20+ amps at 240V. You should not put anything else on the circuit with the dryer.

You are correct that if the table saw can run at 240V, it will draw half the amperage it does at 120V, but not every saw is capable of both. You’ll have to check the manual to find out for sure, or give us the model number and maker of the saw and we might be able to tell you. 1.5-2HP table saws generally use around 9 amps at 240V.

Again, I’d recommend getting a professional to help you with this.

Thanks,

The drier is being run on gas and the electrical is not being used so it would be dedicated for the saw. It has a 30AMP outlet on it now.

I don’t have a specific model saw as that is what i am trying to match up to my now new found outlet. I am not looking to run a 110 saw on that outlet.

You’re golden. With a 30 amp outlet, that circuit should be #10 wire and it’s kind of a pain to deal with. You are not limiting your saw in any way, and don’t be surprised to find a 15 amp plug on the saw itself ( My 3 HP saw came with a 15 amp plug, so did my 3 HP planer.) the nice thing about 30 amps is that you can get a 5 HP saw if you want. I didn’t follow your plan completely, but it would be better to just go through the wall from the garage side and pull that circuit over there. Put a proper outlet on it and have a ball!

Agree with Fred.
I’d check to make sure the outlet is still powered and verify what size breaker it’s on.
If the occupants of the house before you are who put in a gas dryer they may have used the dryer circuit for something else.

Square D makes a 15/30/15 and a 15/20/15 breaker that fits in the space of two normal breakers. Voltage is 110/220/110. Don’t know what code is in your area but even if you panel is full if you have a couple 15 or 20 amp 110’s you could yank them out and put one of these in its place.

No problema. Just wire the saw with a plug that fits. Or do what Fred says.

Trace the drier line to the breaker and check to make
sure it’s actually 220v. It could be an RV charging
circuit, which is usually 110v but the receptacles can
look a lot like drier plugs and there is some compatibility
in the various formats.

I am not looking to run a 110 saw on that outlet.

good thing. that would most assuredly cause any 110v motor to release it’s magic blue smoke.

Guys thanks for the help!!!

Honestly I was ordering 110 saw but got home too late. I honestly forgot all about the dryer. I guess in newer houses they have them set up for both gas or electric. We always buy gas dryers.

I wonder how many others don’t realize they have easy 220 access considering most laundry rooms are near the garage.

I agree with what others have said, be sure and check the breaker, not just the outlet. Your probably good no matter what, but make sure it really is a 30amp circuit before you use it as such. Your saw should work fine on a 20 amp circuit anyway. Most 220 amp breakers Ive seen are 20 amp.

Have your say...
