A Residual Current Device (RCD) can function without proper earthing, but its effectiveness and safety are compromised. RCDs rely on detecting imbalances in the electrical current, and without a proper earth connection, there’s a risk of failure to trip in the event of a fault. This could lead to hazardous situations, such as electric shocks or fires. Therefore, proper earthing is essential for RCDs to operate safely and reliably.

How do you check the residual current device is connected to your power tool?

To check if the residual current device (RCD) is connected to your power tool, first ensure the tool is plugged into an outlet protected by the RCD. Next, test the RCD by pressing the "Test" button; it should trip and cut off power if functioning correctly. After testing, reset the RCD and verify that the power tool operates when plugged in. If the tool does not work or the RCD does not trip, consult an electrician for further inspection.
