A neutral wire is an essential component of electrical systems, providing a return path for electric current. It typically carries current away from electrical devices back to the power source, helping to maintain a balanced electrical system. The neutral wire is usually color-coded white or gray in most wiring systems. In a standard household electrical system, the neutral wire works alongside the live wire (or hot wire) to complete the circuit. This ensures that electrical devices operate safely and efficiently. Properly connecting the neutral wire is crucial for preventing electrical shocks and maintaining the overall safety of the electrical system.
