Clamp-on leakage current ammeters are typically used to measure leakage currents on which type of conductors?

Clamp-on leakage current ammeters are specifically designed to measure the amount of leakage current flowing through conductors without the need for physical disconnection or interruption of the circuit. They are particularly effective on grounding conductors and grounding electrodes, as these systems often experience leakage current due to insulation failure, moisture ingress, or other issues that can compromise safety.

When using a clamp-on ammeter on grounding electrodes, it allows for the monitoring of any unintended current that may flow into the ground. This is critical for ensuring that ground fault conditions or other faults are quickly identified and addressed. While leakage currents can also exist in neutral and phase conductors, the primary purpose of these ammeters is to provide a non-intrusive means to assess grounding systems, where accurate detection of leakage currents is essential for preventing electric shock hazards and ensuring overall system integrity.
