220v hookup

220 volt hookup differs from 110 in that it has a hot and a neutral lead hooked up to the breaker, right? Maybe someone could clarify something else too. The original question is for a table saw hookup. The table saw says that it requires no less than 12 awg wire. So I put in 10/2 based upon a recommendation previously. It says it is 230volts. Unknowingly, I hooked up a 20amp breaker, as stated in the installation manual, however I think this breaker is rated for 110, not 220. I say this because the hot lead goes to the breaker, the neutral to the netural bar, and ground to the ground bar. When I try to power up the saw either nothing happens, just a clicking/buzzing noise, or sometimes it does go. Should I have wired this with the two leads going to the breaker?

Cool

I'm not an electrician, and one of the experts here will explain this in more technical detail, but NO there is no neutral on 220v.
Use a double-pole breaker with BOTH of your 10/2 insulated wires as hots (only) to it.
Good luck!

You need to use a double pole breaker properly installed so that you get 220 across the 2 outlets. You hook the black and the white to the breaker. There is no connection to the neutral bus.
You have hooked it up for 110volts. You will damage the motor if you leave in this condition.

PsyGrad, you have made the mistake of equating the word "neutral" with "white wire". Not all white wires are neutrals.

As joed said, do not try to run this saw any more as wired. You are risking damage to your saw.

OldGuy and joed have already told you how to correct this problem. Mark both ends of the white wire with a black marker to indicate that this white wire is NOT a neutral.
