As you have written in the diagram, 1.5mm flex is only rated to 16A, so cannot be used with a 20A MCB.
Either use 2.5mm cable instead of the flex, or change the MCB to a smaller size.

What exactly are these sockets going to be used for?

What size cable. The IET have issued a correction to BS7671:2008 and at end of correction is a chart see here If it is as chart then OK assuming RCD protected etc.

How is that diagram a ring?

OK i was going to stick the flex to the skiting board.
I will change to mcb to 16A.

They are in a bedroom so TV games console and 2 fish tanks (with a load of 5A for the both of them)

no hair dryer or any high current needing appliance.

Edit- well i suppose it isn't a ring. what would you call you.

Thanks

Its a radial.

Why not use 2.5mm² cable?

Clipping flex to skirting is rough. Use trunking.

Alright.

Could do. Could stick it under the carpet or skirting.

Don't really want to.

DO NOT DO THIS. The carpet will wear on the cable, and the skirting is not a safe zone for concealed cables.

If you want flex clipped around your skirting boards, you go for it son. Nobody here's gonna stop you. Just make sure its on a 16A MCB.

Ok thank you

i will change the MCB and carry on


Thanks for the help

i would deem flex cliped to skirting boards as liable to mechanical damage, why not run some 'D' profile trunking at the top of the skirting and use 2.5mm twin and earth, leave it on a 20Amp MCB then also.

Is there an RCD for the existing socket?
If not, you will need one.

Flex?

Is there a reason why you can't do this in a more *ahem* "permanent" fashion?

Or possibly rearrange the room so the equipment is serviceable by an existing socket?

As you intend to clip flex to the skirting board regardless, why not use an extension lead as this is designed and approved for temporary set-ups such as the one you are planning?

Yes there is a 80A Hager RCD.

The problem is i can rip up the floor broads

Yep that can be done.

Thats what i've got all ready 3 extension lead all linked together.

change of mind i will use 2.5mm T&E and run some trunking.

Thanks
