NEC 220.84 requires all appliances located on a specific branch circuit to be included in the calculated loads for a multi-family dwelling, NEC 220.84 (C). Each small appliance branch circuit is counted as 1500 VA. If the fridge is on a specific branch circuit, does it need to be included in the NEC 220.84 (C) calculation or can it be considered part of the small appliance circuit? It would be allowed to be on one of the two required small appliance branch circuits and would be part of the 1500 VA per small appliance branch circuit. It is the difference between a 1000-amp service and a 1200-amp service.
Fridge is on a specific branch circuit, does it need to be included in the NEC 220.84 (C) calculation

Typical home, You don't know where it will end up. Consider it part of the small appliance BC.
Your home, they can afford it.

OK, I suppose "multi-family" could have been a clue, if I were paying close attention.

...dittoI would do a load calc per apartment, then in your total load do a sum of your general loads, diversify, calc your ranges, dishwashers, water heaters... etc by total numbers and diversify. Annex D has good examples.

220.52(A) exception says:
Exception: The individual branch circuit permitted by 210.52(B)(1), Exception No. 2, shall be permitted to be excluded from the calculation required by 220.52.
This isn't explicitly said in the 220.84 calculation requirements, but it seems like good precedence since you could exclude it in a single family dwelling as it is covered in the kitchen small appliance circuit factors.
