NEC 220.84 multifamily load calculation

[olc]

The optional 220.84 calculation for multi-family typically works out significantly less than the regular calculation.
Any hesitation to use the lower number? (which ever is lower)

Most of the time the optional is lower than the standard. I would have no issue using the optional calculation

I assume you realize that there must be electric cooking appliances or use 8kw if it doesn't have electric cooking, to be able to use 220.84

I have a question on this topic too. If I am doing a calc on a 5 unit townhome that has gas ranges and gas furnaces, I can still use Table 220.84 as long as I include a electric range load? So if I include 8kw per unit I would add a total of 18kw (40kw x 45%) per table 220.55?
