I want to make a 200 Volt extension cord. I know what connectors I need. It will run from a 20 AMp outlet. What wire should I use? 10/3? 12/3? I know it needs a ground wire.

For most of your 220 volt tools, you don't need XX-3, you can use XX-2 w/Ground.
Thanks for the feedback. Yes this is for the PM2000. I only want about a 10 ' cord to maximize manueverability in the 1 car shop. The breaker is 20 Amps. The motor is a 3 hp.

P.S> I like hpm67's comment:rolf:
If you're terminating directly to the equipment, as you indicated earlier it's required if any portions of the equipment have 120volt components. In that instance the 4th wire is a chassis ground.

All good advice on oversizing your wire with respect to your breaker. Yes, 10/3 is a little more than 12/3, but it's not like you're buying 1000' of wire. The price difference is ~$0.30 to $0.40/ft. So to me, it's worth it to have that much extra protection in my home to justify spending an extra $12 on a 30' extension cord.
Again, just my $0.01
