    13A and 16A sockets on the same 20A radial. OK or not?

    I’ve just had a ‘robust exchange of views’ :) with a visiting engineer about the 16A sockets in my workshop. These, together with local 13A sockets, are run from radials in 2.5mm, protected by 20A RCBOs. I say it’s fine to have say a couple of 16A interlocked sockets, and lots of 13A doubles...

    32amp radial

    In a school today helping an approved contractor. There is a over door fan heater on a 32amp radial fed off a rotary isolator. It then goes into a bank of 3 switches that are used to control it. The swtchs are double pole rated at 20 amps. Isn't that a danger being on a 32 amp 4mm mcb

    Radial final circuit

    Hi guys, just started rewiring my house, and noticed the sockets in the attic wired in radial instead of ring. Can I leave it in radial? There are only 2 sockets up there, unlikely there will ever be much load on it. I was thinking of wiring it 2,5mm2, (as it is now) on a 16A beaker. Any...
