Ring Main at Consumer unit

Former Community Member
Former Community Member
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 am beginning to lose it over this thread.

    Andy is suggesting that ANYTHING which is not compliant is at least a C2 for some reason, eg a Plastic domestic CU. No Andy that is not correct, in fact, it is worse than that, it is utter rubbish. If your saying were true, there could be no C3 could there? The only one possible would be the "I don't like the look of that" comment, whit no deviation from the regulations! Insulated conductors are not dangerous as such, they could be damaged, but so can sheather cables. By the sound of your thought andy "clipped direct" is now a C2 because damage is POSSIBLE. This is not the spirit of the regulations, they are primarily about safety and how to achieve it. Exact non-compliance is not a requirement for existing installations (in other words 100% retrospective in action).


    So far no one has made any reasonable case against my coding of the exposed insulation, including Electrical Safety First. It appears that if you use unsheathed meter leads you are now in danger of DEATH. Obviously not, strangely now YOU are all DEAD! Hopefully not, and therefore you understand that primary insulation is perfectly safe to be handled. I do appreciate the comment "C3 then nothing will be done", but ensuring that is NOT the Inspectors job. He must just produce a report, hopefully of excellent quality.


    I have had 3 people this week send me information and asking for opinions. I will help where I can (FREE) but cannot always produce definitive answers. However it is a strong indication that the EICR process is seriously broken, and I intend to try and fix it. Support always welcome, it is presently getting electricians a very bad reputation.
