Rx = Re – re
Rx = True Earth Resistance
Re = Indicated Value re = Earth Resistance
of Earth Electrode
(6) Since measuring current is as low as 2 mA, the
earth leakage breaker (ELCB) does not trip
even if the earth side of the commercial power
supply with an ELCB is used.
* Follow the proper connection such as Fig1.
