WebAny imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage. This value represents an insulation ... himmler experimentsWebMay 17, 2011 · May 16, 2011. #2. There are a number of devices that may cause leakage.
