Most obvious fault here

[littlespark]

First of all, sorry I didn’t take more photos.
Been to a customer to price a job and had a look at his CU. Split RCD half and half.

From this picture, it appears the left hand side rcd is off, although all the circuits are powered.

so. First thought, faulty rcd. Says it’s off but contacts must still be closed.

Further investigation. Turned all breakers off, reset rcd and it held. Tripped on test button.
Reset right hand rcd.... also held.
Turned on circuit 1, which is marked as sockets, (first one off right hand, not in picture) trips LEFT hand rcd.

Without detailing any more, it appears the left hand side bank of breakers are being supplied through the right hand side rcd. Possibly because they’ve mixed up the rfc legs. All the load on the left hand side running through one 2.5mm cable. I think I’ll clamp it out of interest.
Would this happen with just lives mixed, just neutrals, or both?

I’ll update early next week. With more photos

I find it funny how so many ppl say I’m too harsh but yet the first thing most properties fail on is undersized meter tails I.e service head fuse being 80a or 100a and tail size 16mm yet many sparks think this is satisfactory.

only time in 50 years in the trade in 1 shape or another have i seen 16mm tails overheat, is once, and that was a cannabis farm where not only the meter but the cut-out had been bypassed.

? yea I bet It went up in smoke. Yea I know what you mean with “it’s been fine for the past 50 years” unfortunately 50 years ago the regulations were completely different right now 16mm tails should not be covered with 80A or 100A fuses that’s the regulations. I do agree with certain things are over the top and highly unlikely to cause harm

I also have great amount of respect for senior sparks like yourself ?

If 16mm tails have been in use by the same occupants for 50 years without showing distress, and there hasn't been any recent drastic change such as a new electric shower added or teenage grandchildren moving in, it seems a bit harsh to give anything worse than C3.
