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 ... WebELR Wiring diagram . A typical wiring diagram of an earth leakage relay is shown below. Operational power is applied to the terminal A 1 and A 2 of the ELR and the CBCT is connected to the terminals T 1 and T 2.The normally closed terminals of the fault signalling contacts are connected to the Undervoltage release coil of the circuit breaker.
