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

    This question is horrifying. We should NOT provide design advice in this context. I was recently told by a proper designer that he was being asked to do some of the designers primary tasks on a "design" from a well know "consultancy" because they didn't know how! This is the state of the Industry - truly shocking, The answer to this question is clearly "Ask the Chartered Electrical Engineer who is in charge of the design process".

    There can't be that many Chartered Electrical Engineers left now, as the IEE stopped giving them out years ago.
