Ring Main at Consumer unit

My daughter has just had an electrical safety check done and I suspect that the electrician has been over zeleous..

Would anyone care to comment.

There is no grommet where the meter tails enter the consumer unit and the outer insulation stops just short of the knockout.

He has graded this C1. Now my opinion is that that does not present an an immediate threat to the safety of personell

It needs fixing but surely only a C2?

More intriguing. He gives a C3 to the ring circuit because the two legs enter the consumer unit through separate knock outs. I can't find that in the regs

And finally an old chestnut which has been discussed before. A C3 because two radial "circuits" are served by a single breaker.. I have always argued that the definition of a circuit is that it is served by a single breaker. Certainly if both radials were brought to a junction box outside the CU and then connected to the breaker by a single cable it would meet the definition of a radial..

Thanks for your attention

I agree moving out for a C1 is nonsense - for a real C1 the more usual response would be for the inspector to make it safe - either by switching off the affected part of the installation, or by effecting some temporary repair (perhaps applying a temporary barrier even wrapping with tape) or by agreeing some procedural work-around - e.g. my making sure all the adults in the house are aware of the problem and so know not to touch it and any children are kept away. In any event the inspector's responsibility is just to issue an unsatisfactory report and advice - what the response actually is is the customer's responsibility.

I disagree about a C3 though - exposed basic insulation lacks fault protection (chapter 41) - so a C2 in my book.
