I've got some new three-core flex. 2.5mm squared.
It's the sort of thing you would use for an extension lead except I've not seen any that thick before (cable is about the same diameter as my little finger).
I can't see any reason why it shouldn't be used to extend my ring main but I've not seen it used for that purpose (possibly because it would be much more expensive than twin core and earth).
Does anyone know of a reason why I shouldn't use it please?
Thanks very much, Paul
