What does the "Switched" wire do in a circuit?

The "Switched" wire in a circuit is specifically designed to carry current only when the switch is in the closed position. This means that when the switch is off, the wire does not conduct electricity and thus does not allow current to flow. When the switch is closed, the circuit is complete, and the "Switched" wire becomes hot, allowing the current to travel through it to power a connected device or light fixture.

Understanding the functionality of the "Switched" wire is crucial for safe wiring practices and ensuring that devices operate correctly. When a switch is toggled to its off position, it breaks the circuit, protecting the device from receiving unintended power and ensuring safety in electrical installations.
