Of course I understand your post, it is out of sync although well withing regs, I would have ramp tested them myself after to see what the actual trip time were, I would suggest at a guess 20-22 was the reading in ms.

I know it maybe a bit of a stupid question, but where are you carrying out the RCD test? At the terminals?
