For a hotel suite with 'efficiency unit' including microwave, fridge & 20A receptacle for coffee maker, should we consider it as a dwelling unit for load calculations? there is not a permanent cooking facility like stove or cooktop.
Thanks

microwave is just sitting on the counter? some microwaves are permanently installed in cabinets and they can cook an entire meal. Could be an AHJ decision but I would think an efficiency unit is designed for using as a dwelling unit with a kitchen. So 2 App circuits would be required. Otherwise it is a wet bar.

NEC doesn't really clarify what is a permanent provision for cooking, so it is up to AHJ interpretation as to whether or not this will be considered a dwelling unit. If it is then you must have at least two SABC's and 1500VA load calculation for each of them.

This hotel includes 230 Suites, some suites w/ fully equipped kitchen (cook-top, uWave, dishwasher, Fridge, and decent countertop; other small suites w/ only efficiency units (uWave, Fidge, 20A Coffee Maker recept.) all costume cabinet.
From definitions, small suites have no "permanent cooking facility", so was planing to treat them as typical Guest Rooms.
2w/sf @ demand factor + 100% fridge + 100% HVAC

For bigger suites, treat them as Dwelling units.
3w/sf @ demand factor + 2x 1500va SABC + 100% HVAC + Cooktop @ demand fact. (220.55 Col.B) + Dishwash.@ demand fact.(220.53).
Fridge & uWave included in SABC.

Is this acceptable?

In case of adding 2x1500 SABC, then 220.42 demand factor is applicable. Am I right?
I don't see that you are required to use 2 SABC's to use the third category in the table, in fact it says without provision for cooking.

But if they are considered dwelling units then they must have at least 2 SABC's, and you should be able to use the first category in the table for all the combined dwelling units portion of the load.
