Hmmm, Could anybody tell me which table I use for calculating armoured cable sizes in the on-site guide?
I'm self teaching and failing :-(

95mmsq is the smallest size cable, (2 core) to be used for a PME bond of 10mmsq. The min cpc size is 47.5mmsq, the cable delivers 54.1 mmsq. Not practical, so run a 3 core 10mmsq or separate 10/16mmsqIt is also generally sufficient for cables over 95mm.
Plus it is almost never adequate as a bonding conductor when cables are sized purely on CCC. Its only once cable sizes are increased to cope with voltage drop that the armour becomes big enough to satisfy bonding requirements.
