Another question about cables (6.0mm & 2.5)

[OnlQQker]

Around 25 years ago I went to Spain with my girlfriend and stayed in an apartment, as she was unpacking the suitcase I decided to take the consumer unit face plate off and have a look. I was surprised to find what looked like 6.0mm cooker cable forming a ring, when I removed the faceplate from a socket behind the bed it was one cable which looked like 2.5mm. An access panel to the side of the bed revealed the 6.0mm cable with a spur off to the socket. I never got any further than this as my girlfriend was by then throwing a complete tantrum that we was supposed to be on holiday and this would probably explain why I am still single to this very day.

So I was wondering why in the UK we run ring mains? I mean even if we run a ring (2x2.5mm) and then spurred off to each socket this would save a considerable amount of cable and running 2 cables in the wall, though this might not be viable in kitchens. Again I'm just wondering why and have only once come across an old 6.0mm cooker cable in a kitchen that was redundant and used as a kitchen ring in the UK, a ring main (2 x 2.5mm cables) had been attached to it (and no, I didn't do it, it was existing)


Thanks in advance!

Some holiday then? you sound like a friend of mine completely obsessed with electrics, how did you manage to get the tools through customs??

You must have missed this thread:

Short answer to why the UK is the only one with ring final circuits is we are the only one with fused plugs. That makes the engineering trade off very different!

Also look up lollipop circuits !

Lets get this straight, you were on holiday in the bedroom with the girlfriend and you were focusing on the electrics......….Hmmmmm.

25 years ago a screwdriver and pliers were the first thing I packed in a suitcase, mainly cuz I didn't trust the safes so would dismantle things to hide cash in

Like I said that's why I'm single now... Maybe the admin could attach a dating section somewhere here Lol

Thanks for the answers by the way, just looking at lollipop circuits as never heard of that one before!

About a year ago there were lots of ads for dating on here.. ?

Thanks for this @static zap, I looked through Google and ended up back here Lol, where a lot of you had already posted in 2015 Lollipop circuit on a 40A RCBO - https://www.electriciansforums.net/threads/lollipop-circuit-on-a-40a-rcbo.101420/ now it all makes more sense...

This place is a wealth of knowledge!

Neither had I till this forum .. (Quality @ Dan)
(there is another post , quantifying the "Motorcyclists" twinge it gives Electricians = X 1000)

A quick and dirty solution that has the worst of both worlds! LOL!

Seriously, unless the radial-to-ring joint is accessible and documented then you have a testing nightmare...

Just to emphasise it is not the concept of the lollipop circuit I dislike, as that is not really any different from having a sub-main to an out building's CU and then a ring for the sockets there.

No, it is the very high probability of being undocumented and hidden after it was done.
