Wiring a 220 circuit Black to one pole on breaker White to the other pole. This is where I get lost, do I wire the other wire to the Ground Bar or to the Neutral/Common Bar?

Thanks

The first few answers are dangerous and totally wrong! Someone can get hurt with this setup.

White must not be used for a hot lead. It is to be used only for neutral. Black and red are okay for hot, but never white. Green or bare are for ground, what the British call earth.

The only exception is in the line running from a junction box to a switch. Other than that, it is unacceptable to use white for hot.

Spent a few dollars and get the correct wire. Besides, the one you have is likely not the correct capacity anyway.

Sorry to be so blunt, but if you are asking this, you really don't have the knowledge to do this safely. The previous answers that said it was okay, also don't.

220 volts is very deadly and dangerous, don't mess with it because you don't have the skills. Even with the correct answers here, you cannot learn enough to do it safely.

A 220 volt circuit is more likely a 240 volt circuit. However, for the purpose of your question we'll use 220 volts. In order to get 220 volts the circuit is wired with two 110 volt hot legs (power sources). One hot leg conductor is to have black insulation and the other hot leg conductor is to have red insulation. White is ONLY to be used for neutral and green or bare copper is ONLY to be used for the equipment grounding conductor.

Installation of a 220 volt household circuit requires understanding among other things: dedicated circuits, proper grounding, proper wire guage for the ampacity of the circuit, proper wire insulation color-coding, balancing loads, proper strain relief for the conductors, proper fastening of the conductors and the receptacle outlet enclosure, using the proper receptacle enclosure, and utilizing a circuit breaker or other overcurrent device which will disconnect BOTH 110 volt poles in the event that there is a fault to ground on either 110 volt hot leg. In short, it requires the knowledge and experience of a qualified electrical contractor.

Remember, the two primary and life threatening hazards associated with incorrect electrical work are fire and electrocution. If you're not well-versed and experienced in ALL of these concepts and requirements, don't attempt the installation yourself - hire a qualified electrician to do it.

For most AC 220 curcuits black is hot, White is hot, Green is ground or common.
You can buy wire that has two blacks and one white with one green ground. But it cost more money.
It is correct that the ground and the common are the same in panel.

Yes. Either one. In some areas, a "Bonding Screw" ties both together anyway. But, still and the same, they eventually wind up grounded.

Ground it.
