Tips: How to measure circuit leakage current with a current clamp meter?
The supply current and the return current generate a relative magnetic field. The currents should be equal (and opposite) and the opposing magnetic fields should cancel each other out. If there is no cancellation, it means that some current (called leakage current) is returning from the other path, and the only other path is the ground loop.There are many reasons cause for leakage current, one is the load and the nature of the circuit itself, one is the wrong wiring, and the third is the poor insulation.
Place the live wire and neutral wire in the jaws of the leakage current clamp meter as shown in the figure above. If any current can be measured, that is the leakage current, which is returning to the ground loop.
