All I can say is... subjectively it's wrong. Objectively it complies with the regulations, if you disagree and would like to convince me otherwise, please explain (a) how it violates the figure 8 test (the purpose of which is to look for interconnections between the legs of the ring at a point other than the origin, interconnections that could if ill-informed alterations were made result in a situation with the potential to overload a cable) and (b) which regulations it violates and why.
It's wrong, we all know it's wrong... explaining why with actual regulations is a little trickier. Please don't cite Appendix 15 (Informative)... it is not a regulation. Without wanting to offend, it's the regulations equivalent of 'The dummies guide to the ring final circuit as defined by regulation 433.1.204'. It provides a lot of compliant examples, but listing all possibilities would be an impossibility which is why it's informative, it's a quick start guide if you will. As best as I can tell the only actual regulation specifically about 32A ring circuits is 433.1.204, it's entirely possible I've missed some but I've looked hard whilst writing some of my replies to this thread because I wanted to be certain I was objectively correct, but I'm all ears if I've missed some.
Maybe we should look at this another way... how would you code this arrangement if you came across it on an EICR? Which regulations would you cite as those it breaks and why?
Remember... I'm really just playing devil's advocate but I am getting a little tired of late of the blind following of rules. The regulations are the bare minimum, we need to be able to think for ourselves, so if you feel like telling me which code Codebreakers applies to this situation, go right ahead and explain what justifies such a code, backing your explanation up with actual regulations and how the arrangement breaks them.
And for another fun exercise in analysing the twisted mind of this old bint... lets suppose I have a ring circuit and I ran out of 2.5mm on the job, only got an off cut left that's about 18 inches long, only had two more double sockets to sort out... kitchen job, all the cables clipped direct or in the void of a dot and dab wall, so I run a length of 6mm from a convenient place (before anyone asks how I managed to squeeze 2 x 2.5mm and 1 x 6mm in accessory terminals.. I love the new 3 way slimline Wago connectors that take 0.5mm to 6mm cable.. awesome for this kind of thinking... nice maintenance free Wagobox tucked out the way, great it was) to the first of the doubles and as they are next to each other, I use the off cut of 2.5mm to supply the other. Does that comply with the design criteria for a ring circuit supplied by a 32A OCPD? If not, why not? And if this complies... how does the situation described in the OP not?
