Difference between revisions of "Talk:Cable Sizes"

Revision as of 02:33, 17 May 2007

I was not sure what the intention of the "buried" column was going to be. Since BS7671 has a number of versions of buried that could be used:

Method 2 : Buried direct in building materials - this is treated as method 1 (clipped direct)

Method 6 : In conduit in thermally insulating wall with one side in contact with a thermally conductive surface

Method 7 : cables in conduit in masonry

and then there is cable in insulating material which seems to have no "method", but counts for a 50% de-rating straight off.

Methods 1 and 2 are the most likely to be met during DIY I would guess, followed by 7

Any thoughts? Or scrap the column and point em at BS7671 or the OSG?
