[QUOTE="Sidewinder, post: 287433, member: 9512"] No issues with the mcb mixing as they are not mixed, Schneider have issued a memo to this affect. Are they suitably rated? I would not be happy without the armour reliably earthed at the supply end. If the isolators are polymer rotary then I would not be happy if the armour is clamped tight to the plastic and in through the top as the polymer will migrate. I'm guessing exterior due to the bw/cw comment? Bonding for the air-con system? Why 32A mcb's for a 19A load? I would guesstimate with diversity that you should be OK for total load if it is well balanced. What does the volt drop calc out at in comparison with manuf' & 7671 requirements? [/QUOTE]
