- 1). Turn off the main breaker at the main power panel.
- 2). Remove the breaker panel cover. Knock out the next two adjacent slots in the breaker panel cover. This will be where the double-pole, double-throw breaker will go.
- 3). Feed the Romex 10-3 wire into the main power panel. Strip off about two feet of the external sheath to expose the black, white, red and ground wires. Strip half an inch of insulation off all of these wires.
- 4). Connect the white wire and the ground wire to the common (neutral) bar in the power panel. Connect the black wire to the first terminal on the double-pole, double-throw breaker. Connect the red wire to the second terminal on the double-pole, double-throw breaker.
- 5). Leave the breaker at the breaker box until all splice work is completed. Do not plug it into the main power panel yet.
- 6). Extend the other end of the Romex 10-3 wire to the load location. The load could be a lighting system, dryer or electric motor.
- 7). Strip half an inch of insulation off all of these wires. For lighting systems, one set of lights are connected across the black and white wires. A second set of light can be connected across the red and white wires. Electric motors come with a wiring diagram to specify where each wire should go.
- 8). Go back to the breaker box once the splicing is complete. Plug the double-pole, double-throw breaker into the breaker box. Reinstall the breaker cover and turn the main breaker back on to test the new circuit.
