Because the supply conductor size, determines the size of the bonding conductor.I have no idea why you keep referring to the supply conductor size, the point is can a sub main swa cable support bonding when the armour is used as the earth. This will nearly always apply to a three phase supply where the minimum size to support bonding would be 50.0. In this day and age people nearly always use three core cable utilising a core as the cpc for single phase supplies. Otherwise it would have to be 95.0 for a two core.
Yes they do nearly always use 3 core utilising a core as the CPC for single phase supplies. This is because the armour is not acceptable as a bonding conductor.
Yes exactly 95mm2 before the armour would be acceptable for 10mm2 bonding. Which nobody in their right mind would contemplate.
