How many wires do you need for 220?
A 220 volt outlet can take cables with 3 or 4 prongs. Not all 220 volt outputs use a neutral (white) cable, but all will have two hot wires (one red and one black) and a ground wire (green). For example, an air compressor requires 220 volts, but the socket has only three tips.
Does 220 need a neutral?
220 doesn't 'need' neutral because each pulse uses the off phase of the other side for this purpose and AC back and forth but where is the circuit since the power is only looping back to the hot bars.22 feb 2011

Can you split a 240v line?
It is possible to split a 240 volt outlet into two 120 volt circuits. You have to share the neutral in the 240v container and you have to maintain the continuity of the neutral. You do it through coiling the connections.
