could someone please point out to me when diversity factor is to be applied? does it apply to cirtain circuits or to the whole of wiring.
the reason why i ask this is because there are alot of threads on this forum which are leading to confusion. for example, in a 10.8kw cooker circuit, it would require approx 50 amps to protect and would be wired with 10mm2 cable. but if you apply the diversity factor (10amps +30% of remaining current +5 amps (attached socket if any)), the figure is reduced to less than 30 amps and if this is correct then you can do with a 4mm2 circuit instead of 10mm2. this makes a huge difference.
please comment of what is appropriate.
cheers
