    Can i run Twin & Earth outside under the edge of my house?

    I want to get power into my shed. I was wondering if i could run the twin and earth under the edge(lip) of my house and then bury it along my garden and then into my shed so the cable would only be exposed about 10m or so. Please let me know. Many thanks.

    Flat twin cable with sheathed CPC.

    I see they're introducing a new type of flat twin cable with a sheathed CPC. In my location there's no requirement to sleeve CPC/bonding conductors and you never see it done. We just install and arrange wiring in enclosures or DB's in such a way that there's no realistic chance of the...
