Which statement about small-appliance and laundry loads in relation to Table 220.45 is correct?

Which statement about small-appliance and laundry loads in relation to Table 220.45 is correct?

• A. They may be included with general lighting loads and subject to Table 220.45.
• B. They must be calculated separately from lighting.
• C. They are exempt from demand factors.
• D. They are included only if there are more than four units.

Answer: (C)

The concept here is how dwelling-unit loads are handled in the demand-factor calculation. Table 220.45 provides reductions (demand factors) for the general lighting and receptacle portion of a dwelling’s load as the number of units increases. Small-appliance circuits and laundry equipment, however, are treated differently: they are exempt from those demand-factor reductions. In practice, you calculate the general lighting/receptacle load and apply Table 220.45, then add the small-appliance and laundry loads at their fixed values (without applying the demand factors). This is why the statement that they are exempt from demand factors is the correct one.
