32A Radial Circuit

[eyeofthebeholder]

As part of my house rewire, I am wanting to installed a circuit for my TV sockets, but I want it switchable from one or multiple 'master switches' in the room'.

On discussing the circuit with the council's sub contractor who can round the other week to inspect the house prior to work beginning, we agreed that a radial circuit would be the best option and to install a single DP switch before the sockets.

As I want to go a bit 'over kill' as I am not exactly sure at this time how many devices will be connected here, I have installed a 32A Type B MCB with a 6mm cable to a 45A DP switch.

Now, obviosuly (as I have already tried), I cannot use the 6mm cable to connect between sockets as the two cores do not fit in the back. What do you think I should be doing in this situation?

Thanks

Adam.

MK sockets are specced to take 2x6mm cables.

Really.... I will have get a few and try them instead

Thanks for the quick reply!

A 32A radial can, however, be wired in 4mm cable.

A 32A radial can, however, be wired in 4mm cable.

It can just about if the installation conditions are favorable. It is close to the limit though.

Also mixing cable sizes on a circuit is generally considered bad practice and it sounds like he already has some of the 6mm in and has probablly already bought the rest of the cable.

Do you need it to be 32Amp? Could you not get away with say, 20A and use 2.5 or 4mm.

What is the potential loading of the sockets that yopu intend using for the TVs. If it is only a couple of sets, just use a 20A and 2.5mm. It can be a bit of a swine to bend two 6mm in a medium depth back box.

If you're using 6mm², use minimum 35mm box depth.

I am struggling to see what else you could plug into this circuit that would require such 'overkill'. I would assume with your tv you will have all the usual likely suspects such as DVD, video, satellite...

and you would not be intending to plug in your cooker, welder. lathe, washing machine, dishwasher etc. and have them all on at the same time continuously

I would take the advice of 20/ 32A, supplied using 2.5 or 4mm at the most.

Terminating anything bigger is a right pig nigh on impossible.
