WebAug 25, 2024 · The RCD continuously measures the amount of current passing through a wire in one direction, and again through a different wire in the opposite direction. If it detects a difference greater than 300 mA (milliamps), or less in some cases, it breaks the circuit and stops the flow of electricity. WebAn RCD (residual current device) is effectively a safety device which disconnects a circuit in the event that a fault is found which could be dangerous. The principle behind the RCD is based on the Line conductor and the Neutral conductor. The RCD continuously monitors the balance between these two conductors, and if the current is lost, this ...
