I am going to get my planer in the next week or so. I am going to get the JET 16". It will be my first of a few 220V tool. I have plenty of space in my panel to install a new breaker. the run from my panel is at most 30'. the specs on that motor are:
3HP, 1 PH, 220V.

Would 12/3 wire be beefy enough? Or do you think a 10/3 would be better?

Thanks,
Nick
