In a 3-prong dryer cord, the neutral wire is typically the center wire. The three wires in the cord are usually color-coded: black, red, and white (neutral). The black and red wires are the hot wires, and the white wire is the neutral wire.
It's important to note that some older homes or dryer installations might still have 3-prong outlets and cords, but current electrical code standards recommend using 4-prong dryer cords and outlets. The 4-prong setup includes two hot wires (black and red), a neutral wire (white), and a separate grounding wire (green or green with a yellow stripe).
If you are installing or replacing a dryer cord, it's best to check the manufacturer's instructions and the specific requirements of your electrical setup. If your home has a 3-prong outlet and you need to replace the cord on a new dryer that comes with a 4-prong cord, you may need to replace the outlet to meet the current electrical safety standards. Additionally, you might need to consult a licensed electrician for guidance on the proper installation to ensure safety and compliance with local electrical codes.
