    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...

    Adding Light to Power circuit.

    Adding a light to a Radial Power Circuit - the circuit is wired in 2.5mm and on a 20A MCB Now if I add a FCU to my Radial and then wire my light in 1.5mm this should be safe? But what if I don't use a FCU but wire the light with 2.5mm cable? what dangers are there.

    Radial or Ring Final Issues

    Hi all I have just moved in and am in the process of adding some sockets. Am I right in saying that I can add to the circuit regardless of which type of circuit it is as the MCB is a 20a, obviously as long as I'm using 2.5mm t+e not speaker wire etc. I get the issues with RFC where 32a fuse...
