Hi, I need some help locating and resolving a fault on a new consumer unit.
I removed an existing plastic MK Sentry duel 63amp RCD unit which worked fine and replaced it with a new metal MK Sentry duel 100amp RCD unit with a SPD.
No 1 RCD I had 5 circuits. No problems all worked fine.
No 2 rcd I had 4 circuits. (There are no appliances plugged in) when I put any load on any of the circuits it trips out No 1 RCD.
When number 1 trips, number 2 doesn't but the voltage at number 2 drops to 187v
I have removed all the circuits entirely and tried each on their own on No 2 rcd and the same thing happens.
The original board (which had no problems)had 2 x 64 amp RCDs which I know work. I replaced the 100 amp pair with these and still the same problem. I have put the 100 amp pair back on but swapped them around, still the same problem.
I have removed the surge protector, same thing happens
I have now put all the circuits on to number 1 RCD and every thing works fine with no tripping. However I don't want them all on 1 rcd, I can't afford rcbo's yet. But more importantly there is still an issue there that needs resolving.
Any ideas what it might be?
I apreciate any help
