Diversity Factor for 3Ph instantaneous Hot Water in AS3000

[stormy]

Hi,

Just a question from AS3000 max demand diversity table C1 for instantaneous hot water. Will it be the same diversity regardless if it is 3Ph or 1Ph or higher current rating or less?

Same diversity factor (0.33x), just keep in mind this is for consumer mains/submains max demand calculations, the cable and protection should be sized for the full draw of the heater.
