Connect the white wire from the Romex 14-3 cable to the neutral terminal on the electrical device. Connect the bare or green ground wire from the Romex 14-3 cable to the ground terminal on the electrical device.
4. Secure the cable: Use cable clamps or staples to secure the Romex 14-3 cable to the studs or joists in the wall or ceiling.
5. Turn on the power: Once the Romex 14-3 cable is installed, turn on the power to the circuit.

Safety Precautions

When working with Romex 14-3 cable, it is important to take the following safety precautions:

• Wear proper safety gear: Wear gloves, safety glasses, and a hard hat when working with Romex 14-3 cable.
• Use caution when cutting the cable: Use a sharp knife or wire cutter to cut the Romex 14-3 cable. Be careful not to cut the conductors inside the cable.
• Do not overload the circuit: Do not connect too many devices to a single Romex 14-3 circuit. This can overload the circuit and cause a fire.
• Get help from a qualified electrician: If you are not comfortable installing Romex 14-3 cable yourself, get help from a qualified electrician.
