When calculating kitchen load for residential service size, what is required for each small appliance branch circuit?

In the context of calculating kitchen load for residential service size, each small appliance branch circuit is required to have a capacity of 1,500 volt-amperes. This requirement is outlined in the National Electrical Code (NEC). Specifically, the NEC stipulates that each of the small appliance branch circuits that are used to provide power to receptacles in the kitchen, dining room, and similar areas should be calculated based on this load value.

The reason for this specific value is to ensure that there is sufficient power available to handle typical kitchen loads, such as microwaves, toasters, and other small kitchen appliances that may be used simultaneously. Utilizing a standard load value helps in designing electrical systems that can safely accommodate the expected demand while preventing overloads and ensuring convenience and efficiency in residential settings.

Choosing 1,500 volt-amperes aligns with NEC stipulations and reflects an established standard in residential electrical design.
