Yes I realised after, it is getting late lol, about time I was in bed.

I am sure DW eats the regs for breakfast lol

Reg 433.4 also mentions a single device for overload protection (conductors in parallel ), I suppose it is how you define a single device

Yes, I'm off to my pit as well to read another couple of chapters of BS 7671 - it's a great cure for insomnia.

Nice try lol.. a ring by its nature has to have more than 1 point otherwise its parallel cabling disregarding the 2 mcb crap.

But Darkwood...you are forgetting the bathroom fan

Im just bringing a few rarely used commercial/industrial practices into the domestic realm... although in practice i wouldn't apply them to domestic but its just to show after all the slating the OP can do in theory what he wanted with just a slight change on his OCPD .... but it comes back to the physical part of getting 2 x 6mm cables into a pull/wall switch although their are ways again around this too .... i probably only wouldn't do it because the next Electrician to test the installation wouldn't have a clue and would likely condemn it just on the principle that he can't understand why its been done that way.

You be careful using them newfangled ideas on here some don't like it ; )

Thinking about the ops problem ( the electrical one) why not 2 of 6mm T and E into suitable enclosure with din rail mounted bolted terminals. Lug ends onto terminals. The cables are in place already as previously stated. Then use 10mm T and E with bolted lugs to extend circuit. You have then got 10mm to go to the isolator and 2 of 6mm cables in parallel protected by a single 40A MCB. Simple.

Thinking outside the box that's all.

A bit of blue sky thinking can work wonders.

Soz guys was bored and had a few beers last night i always like rocking the boat and seeing how many will scan the regs to find a flaw in my thinking lol....

I spend most of my time finding solutions that others can't find with machinery etc so thinking outside the box is one of my strong points....and in doing so ive had to utilise the clauses that many never need to use.
