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

    So on page four we find out there is a grommet, but in the wrong place.


    So the question is can it be reinstated and the tails repositioned without straining terminations on the new Smart meter?


    By the way if the seals are cut and the main fuse pulled the meter will report you and there may be a knock on the door from the Revenue Protection team before you have time to get it back in again, also everything was photographed when the meter was installed.


    Don't wobble meter tails as the connections can, and do, come loose. Fiddling and moving meter tails can cause all sorts of problems. That is why special large tails' glands are available that grip the tails firmly to prevent loosening of electrical terminals at main switches or R.C.D.s inside consumer units.
