    UK 3 x 2.5mm T&Es into one 13A socket. How do you do it?

    I've always disliked needing to wrangle three 2.5mm T&Es into one 13A socket. The three solid cores rarely sit cleanly, and there's always the suspicion that at least one core is not being held properly: Lately I've been doing this, using 5-way Wagos and bits of stranded 2.5mm single...

    Any tips on wiring 3x 2.5mm cpc's into a 13a socket?

    Every time i go to do this, even with correctly fitting sleeving, it seems to be a right **********")£"$$* of a job getting all three in snugly without the sleeving riding up and making it difficult to tell whether i clamped on sleeving or copper. Any tips for not fighting with this? It just...

    Amp rating on spur - 2.5mm Cable

    Can I please check my understanding on the following. My ring is wired in 2.5mm T&E. It is on a 32 amp MCB and protected by an RCD. I am now contemplating a spur from one of the ring circuits to provide power to an electric hob. The Hob is 2.5KW which I believe, equates to 11 amps. If this is...

    Why can't you join 6mm and 2.5mm?

    Saw this thread in the DIY forum but can't respond and i have a question: Everyone seems to be going mad in the thread suggesting it's dangerous but this seems fine to me. Since it's only a pump now, as long as the MCB is downrated to a max of 20a it should be fine, no? Sorry if it's a stupid...

    Stranded 2.5mm T&E cable

    Recently a couple of threads have discussed T&E cable and it became apparent to me that the 2.5mm, which I have only ever seen as solid core, is available with the live cores in 7-strand (rather like the old 7/.029" imperial size, though with solid CPC and not the 3-strand seen before). In fact...
