SWA ref method

Farmboy
Hi all, a 6mm2, 3 core, XLPE SWA cable lays in a void under a bungalow ground floor (the sub floor is concrete, with 450mm stub walls, on which sits wooden floor joists and wayrock wooden flooring - the swa lays unclipped/loosely on that concrete floor). So, what reference method and ccc table should be used in apdx 4?

    Well at that size you could probably have a 45 A breaker and protect the cable more than  adequately - I presume that either the folk who fitted it were  going to come back and add a lot more load, or they were using up an offcut or  perhaps skip salvage  from another job. If need be, problems with tripping on inrush - if they do welding outside or something-  a 32A MCB or RCBO could safely be substituted.

    Clipped direct to a vertical wall would be about 60A, and as this is not quite as well ventilated perhaps 50 odd. plenty in hand.
