Use a leakage current breaker designed for suppressing harmonics/surges.
Find the terms of Equation (13.2) from the diagram.
Ig1 = 95

= 0.475 [mA]
Ig2 = 105
1000
5
= 0.525 [mA]
Ign = 0(not used)
Iga = 5 [mA]
Igm = 2.5 [mA]
Insert these values in Equation (13.2).
Ig
10 {0.475+0+5+1 (0.525+2.5)}
85 [mA]
According to the result of calculation, use a leakage current breaker having the rated sensitivity current (Ig)
of 85[mA] or more. A leakage current breaker having Ig of 200[mA] is used with the NV-SP/SW/CP/CW/HW
series.
