WebThe clamp-on methodology is based on Ohm’s Law (R=V/I). A known voltage is applied to a complete circuit and the resulting current flow is measured. The resistance of the circuit can then be calculated. The clamp-on ground tester applies the signal and measures the current without a direct electrical connection. WebPortable/handheld appliances have to have earth leakage current of less than 0.75mA to be considered safe. Other Class 1 appliances such as IT, movable and stationary equipment have a limit of 3.5mA. Class 2 appliances – 0.25milliamps. For Class III appliances the limit is 0.5milliamps. Notes on the above (from the IET Code of Practice):
