If this isn't a wind up you need to find an electrician who is NICEIC registered. https://www.niceic.com/householder/find-a-contractor
That is still not safe that flex coming out of the 20A middle breaker is underrated.
If anyone was to do an EICR on that it's going to be a long list of faults.
As in my first post if this is living accommodation you need to rectify that ASAP.
Yeah it's a really old one not actually sure tbh but it's fine it's all sorted now I swapped out all the trips and move the rcd to the right and re wired it properly then had a sparky to come.make sure I did it correctly but no its not correct mains cable and no I'm on a 32 amp now and had no problems since
Thanks mate was a worrie for a minute then not being funny maned up and got it done the hole thing would.of cost me 250 for a sparky to do for me I ended up shelling.out 60 quid lol
