Apartment load calculations

[e2me2]

I was asked to do a load calculation on a 15 unit apt with electric range dishwashers and disposal but no specs were given is there a general rule or a common kva for the every standered range when i have a print but no appliance specs

By the time you apply the range demand factors for 15 electric ranges, it won't make that much difference whether you pick 8, 10, or 12 KW. Table 220.19

I just went on the "Hotpoint" website, as they are a popular generic electric range often used in apartments. Most every rental grade plain jane model I clicked on was around 10KW. http://products.geappliances.com/ProdContent/Dispatcher?REQUEST=HPTPRODUCTSELECTORINDEX&prodline=Cooking%20Products_Electric%20Cooking&prodline=Cooking%20Products_Gas%20Cooking&prodline=Ventilation%20Systems&MASK=Approved%20Models_SalesNet_CustomerNet_Consumer%20Ready_Full%20Hotpoint%20Collection_Hotpoint.com

Why would you want to take it upon yourself to make what could be costly assumptions?

But it will make a difference when you calculate the feeder to each unit.
