I have had a new consumer unit fitted, all seemed to work OK until night came and then lights tripped, I will guess until the two security lights were energised there was not enough current drawn as LED's don't draw much.
So found in the hall behind the 4 gang intermediate switch there are 4 black wires in a connection block and removing one stops hall lights working and stops the RCBO's from tripping, I will guess since hall lights on the wall they have been wired different to rest, but there is the standard red, yellow, blue going to two switches so there seems no reason why it needs borrowed neutral to work.
The consumer unit is not even in the house, so not easy running outside to reset or on/off and the RCBO do not switch neutral so trying to think of a way to test to find what does what.
I can take the easy way out and combine upper and lower floor lighting, but I must be having a senior moment just can't think how to correct the problem. Can't find clamp on and it would not measure 30 mA anyway.
