The black wire is the hot wire through which the electrical current flows to the appliance. The left over voltage which is usually zero flows back to the main circuit panel through the white neutral wire where it flows to ground.
To control a 220V circuit with two hot wires using a relay, you would typically connect one hot wire to the common terminal of the relay and the other hot wire to the normally open (NO) terminal of the relay. When the relay is energized, it will close the circuit between the common and NO terminals, allowing the electricity to flow through the circuit. Be sure to follow proper safety precautions when working with high voltage circuits.
a shorted out outlet can cause a backfeed on the white wire, an open circuit on the white wire with and electrical appliance plugged in to an outlet can cause the same type of backfeed
for safety purposes the safety ground in normal operation, both the hot and neutral alternately
To wire a 3-wire appliance to an L14-20 plug, connect the green ground wire to the ground terminal, the white neutral wire to the silver terminal, and the black or red hot wire to the brass terminal. Make sure to follow proper safety precautions and consult a professional electrician if you are unsure of the wiring process.
The typical rating of a hot wire relay contacts is 35 amp
Yes. Older refrigerators used a hot wire relay in the starting circuit of the compressor.

To avoid a shock if the hot wire in the appliance should come in contact with a metal appliance part that the user could touch.
You can use a wire tester to determine if a wire is live. You can also touch the positive wire on the ground wire, if the wire produces a spark it is live.
Relay problems or a floating hot wire.
Take the relay out and hot wire the pump. If it works, its not the pump.
