What color is usually designated for neutral wires in electrical systems?

In electrical systems, the color white or gray is typically designated for neutral wires. This designation is important because it helps ensure consistency and safety in installation and maintenance. The neutral wire serves as a return path for electrical current and is connected to ground at the main electrical panel, providing a reference point for the electrical system.

Using standard color codes, such as white or gray for neutral wires, aids electricians and contractors in identifying different types of wires quickly. This can prevent mistakes, such as connecting a live wire to a neutral, which can lead to dangerous conditions or equipment damage. Proper adherence to these color codes is also critical in helping ensure compliance with electrical codes and regulations that promote safety in electrical installations.
