Find the terms of Equation (13.2) from the diagram:
Ig1 20
Ig2 20
Ign 0 (not used)
Iga 0.1 [mA]
Igm 0.1 [mA]
Insert these values in Equation (13.2):
Ig 10 {0.1 0 0.1 1 (0.1 0.1)}
4.0 [mA]
According to the result of calculation, use a leakage current breaker having the rated sensitivity
current (Ig) of 4.0[mA] or more. A leakage current breaker having Ig of 15[mA] is used with the NV-
SP/SW/CP/CW/HW series.
