[QUOTE="meerkat, post: 193464, member: 3117"] Hi Plumber, this is what I was trying to say in my original answer to soulman's post, so diversity only affects the load, diversity is only used when considering a group of circuits as found in a CU, where not all of the capacity of every circuit is being used, therefore we wouldnt reduce the circuit protection on a single circuit as it is there to protect the whole circuit load, should it be used. Diversity is used to calculate the cable size and protective device rating of the cable which feeds all of all of the circuits of a CU, as most of the time only a fraction of the total capacity of each circuit is in use, does this make sense or am I not getting this at all, cheers (MEERKAT) [/QUOTE]
