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

    IG 11 is of course an Ilford postcode, and for those not London or Essex based, zone 11 refers to Barking, which is  not far from Dagenham on the map.

    However it is the phrase Barking Mad, presumably so named after anyone silly enough to want to live or work anywhere near London, that we are after here.


    Or just plain barking as in somebody's behaviour which is not entirely rational, but which does not satisfy the definition of an illness. So glad that my remark did not fall upon stony ground. ?
