That could only happen if the neutral wire (white) becomes disconnected at either the panel, the meter base or the transformer.
3 OR 4 . you only need 2 wires for 220, 1 phase is 120v between 2 of them its 220v . you also should have a ground for the third wire ,and the newer stuff requires a neutral or white wire for the 4th wire. hope i helped , D
Yes.
In common house wiring, black is the power wire, white is the neutral, and green is the ground wire.
Don't!

Use AWG #10 wire on a 20 amp breaker.

Wire the switch to the hot/black lead.
The voltage is lost at the slice.
Yes.
You would need a 12VDC to 120VAC power supply.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
With one interpretation of this question, the answer would be two 120V wires and a ground.
