    Three way and single pole

    Do I need to have 2 power sources if I have a three way switch and a single pole switch in the same electrical box? The three way will have another switch at a different door for inside lights. The single pole will be for an outside light.

    Diversity Calc Commercial Dishwasher 6.5kW single element

    It is a 6.5kW thermostatically controlled water heater if you ignore the rest of the gubbins. So that would be a Purpose #6 for diversity ie: None allowed. = 28A. But you could treat if like a cooker too. Purpose #3 ie: 10A + 30% FL current over the 10A. = 15.4A What do you think? Thanks
