A mobile van converted into office with circuits supplied from a 3000w inverter and to a 3 position change over switch to a ccu with rcd protection .the cable from c/o switch is a 2.5mm2(iz 27A) to the ccu and circuits are as follows
1 16a mcb supplying heater 1000w on a 1.5mm2 cable
2 16a mcb supplying one socket outlet 1.5mm2 cable
3 16a mcb supplying a sfs for kettle 1.5mm2 cable
4 6a mcb supplying 3 lights. 1.5mm2 cable
the changeover switch can only supply one circuit at a time so the 3000w inverter produces max current approx 12a therefore circuits wired in trunk so realistically the criteria ib<in<iz is met because 1.5mm2 cable current carrying capacity is approx 21a? (without getting book out) so am unsure whether or not this conforms TO THE REGS?
