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

  • Hopefully the case in question is not quite as rough as that.

    But even if it was that rough, that does not warrant moving house while it is fixed, just being aware and keeping an eye on who has access to it until it can be made good..

    (And the instant temporary fix to demote a C1 to a C2 is a turn of self amalgamating tape or that awful putty like stuff you sometimes see that ruins perfectly good trousers)

    It is quite common to have a flash of colour on show  for the last cm or so with the  grey tails cut slightly short to identify the polarity of the  core within.

    Not really the way to do it, and personally I prefer a turn of the correct coloured tape, but I am not everyone.


    Mind you the gap between the ideal and what remains actually still more or less safe in practice is quite large.

    To set an expectation of what fok can live with for years, without having to moving out while it is fixed, this picture is from another thread showing some wiring in Azerbaijan.

    Certainly a lot of Eastern Europe wiring was like that before the fall of the iron curtain, though most of it has now been improved, but even back then accidents were pretty rare, but perhaps folk were rather more clued up to be careful and did not expect things to be intrinsically safe and to work unattended.
