There are three methods that can be used for calculation:
Constant
You use the Constant method to set a demand factor for all
objects that use the load classification to which the demand factor is
assigned.
By Quantity
You use the By Quantity method to assign a demand
factor to multiple items. You can assign different factors to ranges of
items or the same factor to items, depending on how many there are.
Figure 14.8
shows this method used for a motor load classification. The
calculation option is set to calculate incrementally for each range. The
ranges defined, result in the first motor load being calculated at 125
percent and any other motors at 100 percent.
Figure 14.9
shows this
option used for clothes-dryer load classification. The option is set to
assign the demand factor to all objects within a range that defines the
