No cpc on lighting and no neutral continuity on kitchen ring

[Muzza115]

Hi All,
I recently replaced an old rewirable fuse board for metal split load rcd board. However on testing prior to replacement I noted that one of the lighting circuits doesn’t have a cpc. I’ve put this in the EIC for the new board that no cpc for lights, advised client that needs rewiring and advise against metal fittings accessories etc,is this the right course of action to take? They do already have metal fittings on this circuit, Is rcd protection enough to cover this? Also the kitchen ring has no continuity on the neutral conductor, I’ve had all the accessories off to find it but can’t, I’m assuming the break maybe in a buried joint box as the kitchen is an old extension. What’s the best course of action to take regarding this please?
Thanks

Agreed. Can’t see the point of upgrading half of the supply. Dangerous also.

Disagree 100%

there is no way any normal residence in the UK is ever going to pull 84 amps long enough to burn out the tails.

You can use the maximum load to justify not upgrading and be VERY careful removing seals from the meter.

wash your mouth out with soap... removing seals from a meter... as if anyone would contemplate that.... oops, seal fairy just whisprered in my lug hole.

would that not get pulled in an assessment though?

No as cutting a seal off would be classed as criminal damage. There's a lot of risk involved in pulling a DNO fuse hence the reason why they like to charge us vast amounts of money to do it for us.

Depends on the DNO; SSE allow removal of their main fuse by sparkies in a scheme, not Stroma 'cos they don't charge enough!

Verify your DNO policy OP.

One option as a temporary measure with the N break would be to reduce the OCPD rating to 20a leaving the circuit as it is. An explanation could be provided on the EIC that the circuit has been protected from overload and investigation and repair will be carried out at a later date on the clients instruction.
If it was not practical to fix before the NIC visit thats what I'd do.

Thanks Wirepuller,
That’s something worth considering as time isn’t on my side. Do you think that would satisfy the assessor?
Cheers

i'd think that would be OK as you would have shown that you'd done everything possible to minimise the risks, and that it's the customer who has the final say on whether he's prepared to pay for a permanent fix. but get it on paper.

Do you know which sockets/outlets the break is between? as if you intend to change the protective device to 20A the NICEIC will take a dim view of the live being left as a ring you will need to test as two radials below earth loop limit. The loading, diversity and distribution of
the sockets would be a factor especially as it is feeding the kitchen.

As above, a faulty ring energised with a lower value ocpd is still an energised circuit with known faults.

The kitchen actually has two rings to it. As is an old extension and assuming from when this was done. I haven’t established which outlets the break is between yet.

Well get yer finger out sunshine chop chop.

The most common reason for a "break" in a ring is a lose connection at a socket or fused spur

Shouldn't take long to locate.......

Or some div with a pair of side cutters with a big bit missing from the blades.
