Twin and Earth cabling

courtney blythe

Hi,

I'm using twin and earth cables for a office building refurb. In the BS 7671 regs i can only see cable current carrying capacities for these cables in thermal ceilings and walls, this will not be the structure for the office building internally. How can i size the twin and earth cables?  I.e are there alternative tables?  I hope you can answer soon.

Regards

    Any reason you're not using singles?

    If cables are going to be flung about above grid ceilings I'd prefer they were sheathed T&E rather than unsheathed singles! (not merely a rhetorical point, I have actually seen unsheathed singled go up a partition wall in conduit and then run unenclosed (other than the ceiling itself) over the tiles).

    We are using T&E because it'll be a cheaper and faster installation. It's not impossible to install the cables neatly as far as possible. Thanks for your opinion.
