Two of RCDs are already in use for many years, other two are new!
At first i took a test on a ABB 40A/0,03mA about 8-10 years old. It did not pass it anyway. Tripping Ampers was out of limit, i assume about 40mA.
Next test was about an old RCD (F-G permat)...
Received an email at bang on 12 today with my results. To my surprise i have passed everything! I was certain i failed most of it but wow! WELL happy now :D

Any ideas???
