1)
The so-called live measurement is only advisable if there is no bias cur-
rent within the system. Only suitable for motor protection switches with
small nominal current values.
15 mA test current, only applies if RCD is set with IΔN = 30 mA; other-
wise test current = ½ · IΔN of the pre-set RCDs
