How do you wire a 4 wire to a 3 wire?
Connect the ground wire of the 3-wire cable to the ground wire of the 4-wire cable. Connect the black wire of the 3-wire circuit to either the red or the black wire of the 4-wire circuit. The red and black wires are the”hot” wires. Either wire can be used to power a circuit.
What size breaker do I need for a 240V dryer?
