multi-family feeder calcs

[malachi constant]

I'm confused. 220.84(C)(2) calls for 1500VA to be included for each laundry (and small appliance) branch circuit. Then 220.84(C)(3) says that nameplate ratings must be included. It specifically mentions clothes dryer, but not washing machine.

Can I assume that if I have nameplate data on a washing machine it should be disregarded?

What about stacked washer/dryer units? Can I include the electric dryer and disregard the washing machine motor?

Since the washing machine is already covered under 220.84(C)(2) and is not mentioned in 220.84(C)(3) this seems like the right approach to me. Thoughts?

No ...You must still include the 1500va laundry circuit 20amp per 210.11(C)(2)

No ...You must still include the 1500va laundry circuit 20amp per 210.11(C)(2)

and the nameplate rating on the stacked unit
