    multi strand 2.5mm T&E - is it OK to use?

    Hi, I've been working in a relatively new house (approx 5 years old) and the kitchen ring is wired with 2.5mm, twin and earth in which both the line and protective conductors are multistranded. Is this OK to use? I've never come across it on 2.5mm cable and they have nuisance tripping on this...

    32A mcb on a 2.5mm cable

    Just wanted to see if I'm being a bit too 'picky' but I've come across a few installations recently which have a 32A mcb for a radial circuit using only 2.5mm cable for which the current carrying capacity is approx 26A. I've been picking it up but it seems to be quite common. What do others do...
