[QUOTE="Robojin, post: 38343, member: 2209"] I'm in Badgers camp on this one, 2x hobs have been asked for by the client, so we have to presume they intend to use them at the same time or why would they have them, 2x cable runs IMHO however based on the OSG, for diversity in domestic dwellings we have 10A+30% of fl in excess of 10A, which = 2.3kW+2.9kW= 22.65A (assuming 30% full load above 10A), having said that, should you treat this as more akin to a guest house, where you would more likely encounter two hobs?, for that it's 100%+80% = 10,800kW or 46.96 amps load, so 47A cable is too close for comfort And just suppose at some stage in the future your installation fails under load, (at a peak time Xmas?) consider this, 1) you are protecting the client 2) protecting yourself since your name will be on the EIC Robojin [/QUOTE]
