Which category of load requires specific calculation in multi-family dwellings aside from general lighting and small appliance load?

In multi-family dwellings, the kitchen equipment load requires specific calculations alongside general lighting and small appliance load due to the unique demands and potentially high energy usage associated with kitchen appliances. This load includes various equipment such as ovens, refrigerators, dishwashers, and microwaves, all of which can significantly influence the overall electrical demand of the dwelling.

Properly assessing the kitchen equipment load is essential to ensure that the electrical system can handle the expected usage without overloading or causing safety hazards. Understanding and accounting for this load also contributes to accurately sizing feeders and services to maintain efficiency and reliability in the electrical system.

Other categories like heating load, vacuum load, and cooling load are also important, but they typically follow different criteria or standards for calculation and may not have as significant an impact on the initial electrical service requirements as the kitchen equipment load does in multi-family settings.
