Hi,
I am calculating the existing service of 32-unit apartment
using optional calc 220-84
do I have to allow (32) x 8000VA for range and not used

or I am allowed to demand factor it per 220-55 ; 32 x 8000VA x 22%
?????

Thank you

In optional calcs you must use the nameplate rating. If the cooking is gas then you would have to use 8kw for each range to be able to use 220.84
