The installation is similar to that of a 120V outlet. The part you have to be careful with is getting the correct size wire and breaker.

240V is installed using 3 conductor wire (Black, Red, White). The Black and Red hooks to a double-pole circuit breaker. The white and grounding the same as a 120V system.

You actually don't need a 3 wire cable for a 240 volt outlet. The neutral more than likely will not be used and a three wire cable over a two wire cable adds extra costs to the overall job total. If you can afford it however, it is a good idea as then the outlet can be used as a split voltage outlet, and the wiring is pre installed.

There will be 2 wires for installing a 240 VAC outlet. One red and one black.

Of course it is physically possible. However, I strongly suggest you check with a qualified electrician who knows the particular electrical and building codes for your area as they can vary. Done incorrectly, you run the possibility of electrocuting yourself or someone else who uses that outlet, or setting your house on fire.
