I have an exposed 110 volt wire colored white that an electrician put in for some outside lights. That was never done but the wire is still there. I also have two yellow wires coming from the breaker box. These and the white are within six feet of where I would want the 220 outlet. Can you make a 220 from either of these scenarios? Also, the breaker box is just on the other side of an outside wall with a 110 outlet already there. I can gain access to that outlet through the sheetrock, so could that be converted to 220? thanx

Not enough info.
There is no such thing as 240 volt outlet without know the amperage required.
Do you need a 120/240 circuit or just a 240 volt circuit?
Do you need 20/30/40/50 amps?
The white and yellow wires, are they cables or individual wires?
