What is the main goal of the Earth Leakage Test?

The primary goal of the Earth Leakage Test is to identify any unwanted electrical current that may be flowing to the ground, which can pose safety risks. This test is crucial for ensuring the integrity of an electrical installation, as it helps to identify potential faults that could lead to electric shock hazards or fire risks. By monitoring earth leakage, technicians can determine whether the insulation of wiring is compromised or if there are faults in electrical devices that could allow current to escape the intended circuit path.

This detection is vital for maintaining safety standards in electrical systems, ensuring that any issues can be addressed before they lead to more serious consequences. The test effectively evaluates the performance of earth leakage protection devices, such as residual current devices (RCDs), and confirms they will operate correctly in the event of a fault. This directly contributes to the overall safety of the electrical installation.
