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 that the removal of only sufficient outer sheath in order to be able to identify the tails is best, but I fail to see a problem with removing more inside the CU: it does reduce the bulk.  


    Hear, hear, well said Chris. Also the modern carp tough copper meter tails are difficult to bend easily. Whatever happened to the nice easily bendable stuff? I normally do the sharp bends and then afterwards cut the strands all off square with my BIG cutters, as they come out of alignment after bending. Don't yer ands ert after manhandling modern tails?
