The small-appliance and laundry loads shall be included with the general lighting load and subjected to the demand factors provided in NEC Table 220.45.

The small-appliance and laundry loads shall be included with the general lighting load and subjected to the demand factors provided in NEC Table 220.45.

• A. shall
• B. shall not
• C. may
• D. must be excluded

Answer: (A)

In dwelling-unit load calculations, the code requires counting the small-appliance receptacle loads (like kitchen outlets) and the laundry loads together with the general lighting load. This combined load is then adjusted using the demand factors shown in NEC Table 220.45. The reason is to reflect typical usage patterns and avoid assuming every device runs at full power at once, which would overstock the service. The table lets you apply percentage factors to that total so you get a realistic, not overly pessimistic, service size. So the requirement is to include them and apply the table’s demand factors; options suggesting it’s optional or that they should be excluded don’t fit the NEC rule.
