Socket ring circuit 6mm to 2.5mm - interesting!

[kkkkk]

Hi all
Working on a site with a general builder who planned on doing all the electrical work - total rewire - on the job, and is miffed because the home owner decided to call in a qualified electrician and get his certificates - builder has run some lighting cables, any old cable he had lying about (4 core/immersion heater cable/etc), which I'm replacing - and told us that he was going to run the ring circuit to start in 6mm T&E from the Consumer Unit, then (after an unspecified distance) to a junction box to split into 2 x 2.5mm T&E. Obviously he wasn't going to test, or notify, or certificate the work. Like to see the comments

I was not getting "personal", rather, I find it hard to understand why experienced sparks would ask the NIC (or anyone else for that matter) for guidance or comfort on such an issue. If it is not your opinion why are you trotting it out on here??

I know a lot of sparks on hear dis the nic and other reg bodies, but I personally have never had reason to complain about them.
Your comment on hard to understand why experienced sparks contact nic for advice is strange, as that is one of there functions. You could say it's hard to understand why experienced sparks ask this forum for advice.

I have contacted the nic in the past for a second opinion, but I know in the end it's my decision that matters.
I've also contacted this forum for advice.
Nothing wrong with that as far as I'm concerned.

How on earth did you fry their server by correcting it.

They claimed we had damaged it by switching the power off repeatedly testing the RCD. I think they were just out to get money off the bill.

Well that certainly WOULD be likely to kill any computer unfortunate enough to be powered up at the time on the circuit concerned.

Why would you test the RCD with MCBs switched on?

Why you ask so many questions???

I have spoken to NIC & a "lollipop" ring circuit is described as being unconventional, not incorrect, but not advisable - as said, it has been used when alterations were done in existing wiring where an old cooker circuit has been used. The main reason it is not a good idea is for the future, when testing is done and the joint where the 6mm joins the 2.5mm cannot be tested, as it would normally be hidden from sight and probably inaccessible, plus a future tester would not know the format of the circuit. Thanks everyone for your input, I had not heard of this before.

Run a 6mm to an isolator then a ring from there on, quite popular in schools, workshops, labs etc.
