Is there a such thing as a 100ft 220 volt extension cord? and would it work in my dryer plug? To run my 3hp Unisaw.

I have never seen a long extension cord made with 220v plugs on it. You can take a regular cord and put 220v cord caps on it. I would get a little larger gauge than the minimum size though.

Usually best to make your own. Buy the male and female dryer ends and 100’ of 10-2 with ground wire. or you can just use the female end and wire it into your breaker box.

I’m not aware of any over 12’ but I have heard of people running 220 well pumps
with cords as long as 100 feet. It depends on the wire gauge of your 30 amp circuit and
the gauge of your extension cord and the motor size on the Unisaw.

I know someone who said he could run a 100 ft. 220 extension cord and stay within limits
as long as the wire diameter on the extension cord was 8 gauge.

Of course, I’m not an expert. Just passing along what I heard.

you can put whatever plug on the end of a cord that you want. At this Length and power requirment I would say you would need a GOOD 12AWG cord. Not just the cheapest peice of shit out there. I’m sure you could buy a 220v cord. Or I’d just goto an electrical supplier and buy 100’ of 12-3 cord and ask for a male and female 220v cord cap

Depending on how much that motor actually draws you may want a 10-3 cord

+1 for Roger. 100 feet- 10/3 w ground. Buy the plug and receptacle- it will be cheaper to make your own.

Why do feel you need a 100’ long 220 volt extension cord? No power to shop? Jobsite use?? Many here know a great deal about electrical and might be to help with any of the above.

Why not 10/2? This is what I use.

Curious, apparently you didn’t like the answers you got on another site, so asked the question here and are getting the same answers. Maybe you should ask the same question again on another site. lol

50 amp RV cords are generally made from 6/3 SJOO. They come in 25’, 35’, 50’ and 100’ lengths.

Just be aware that you’ll be paying a premium. I have a brand new 35’ and it was $215.

10/2 will not work you nee 2 hots a neutral and a ground. I would go with 8/3 personal NEC calls for 10/3 for runs up to 150 feet. this will be an extension cord so you want to factor in the run from the panel to the outlet and the cord from the tool as well. 10/2 no longer meets NEC standerds. im a fan of twist lock conector for the ends. just be aware the is not going to be cheap no mater witch way you go rv cords are a poor choice for it would be over kill and 10/3 or 10/4 cable is about 250 bucks for 150 foot roll. while i would say 8/3 is the way to go i think you would fine with 10/3 or 4 if you find your under 150. btw i keep saying 10/3 or 4 because cord which is what you want is often sold as 10/4 rather then 10/3. ultimately you need the cord to have 4 wires.

If the plug from the saw has 3 wires including the ground, why do you need the neutral?
