It's stated on p82 or p84 of bs7671 that every single leg of cable on a ring final circuit has to be able to manage 20A alone for the ref method it's Installed. P364 of bs7671 gives the current carrying capacities of twin and earth cable. A ring circuit wired with a ref method of 101 in 2.5mm...
Sorry I should have said that before, each one separately protected by its on Mcb inside the hook up. So the regs mentioned above are satisfied, im just worried about the loops in and out to each point, being on the 63A mcb
I'm doing a EICR on a caravan site. Came across 5 circuits each supplying about 13 16A socket outlets. All are protected by 63 A mcbs and all wired in 6mm twin armoured cable buried underground. The cable rating for the cable is 46A with the ref installed etc.

I'm not...
Haha access to tea is probably a tickbox on the contractor assessment. I think if they get the impression that you understand electricity is dangerous and why it's important we follow the regs and manufacturers data of what we install, then you can't go far wrong, as long as your knowledge on...
I had to do three notifiable jobs for my NICEIC assessment all on different sites. Did you not receive a guide to help you pass first time when you paid for the assessment?
My advice is to just relax and take it as it comes. Don't be afraid to ask questions either, the guy I had really knew his...
