A quick check on if replacement CU is required.

[Adrian Haslett]

I had a new extension done recently and the extension electrics have been added to the ring main of the downstairs sockets etc accordingly. I am being told though the work can not be signed of unless the plastic CU fitted only 3 years back is changed for a Metal one following Jan 2016 regs. Their are no new connections to the CU as part of the extension, so can someone confirm this is correct as it seems its an additional £250 Supply and fit for this.


Thanks

@Adrian Haslett not sure what you want from here to be honest. We're (mostly) working electricians who get paid for their time. This forum is mostly for electricians to help other electricians as far as I see it. I try to help non-electricians when I can, however many times people have said on this post that you need to pay for an electricians services for what you are asking.

I really don't want to be rude or negative, but I feel your banging your head against a brick wall here. It sounds like you understand the principals to an extent, but you really need a professional with experience by the sounds of it.

Unless someone else has time to give away for free that is!

Hello. Hence why i am trying so hard to do as much identification as possible myself. How do the pro's out their rate the blue insulation connecters that you crimp wires together with. I liked them until one failed me recently. I still think better than the screw in connecters but i note new type connecters on market that you put wires in and push down with fingers / wago connecters. Are these better than the crimping method ?.

Out of interest what type of circuit did you use the crimp on?

Hello All. Today i have pulled alot of floorboards up etc. Found builder had done a few joints using the screw in connecters with no sleaving on earths. Sleeved the earths but that would not cause the issue. I then set about the only socket not passing conuity test. I found that this was actually a spur which also had a spur for downstairs combi boiler taken from it. Weird. Their is a socket the other side of wall where that spur was taken from. So i added the spur to the ring main by removing one of the the 2 live sets from the ring main socket, making s joint and passing through wall to prevois spur and then running from that spur back to the socket. It then passed its conuity check. Although this is good, i would have not thought that this was why it failed check at consumer unit as in theory the spur would have not altered the ring. However all sockets are now passing conuity test i.e turning of power, removing the to lives and testing accross both, then neutrols etc. I can test no more but will ask the electrician to come back and test from CU again. If fails it must be a break in the final leg back to CU in theory ?. I realise that you are all pro's and you are using your valuable time advising and i thank you. I
On my part was simply doing as electrician advised. Calling him back once all sockets havd been checked etc. I thank you all for your time and wish you well. Put floorboards etc back. Tidied up room and having a cuppa now

Glad you've found your problem. Hope it all tests out well.
