The feeder load for each small-appliance branch circuit required in a dwelling unit is calculated at what value?

Each small-appliance branch circuit in a dwelling unit is required to be calculated at a value of 1500 VA. This value reflects the minimum load requirements outlined in the National Electrical Code (NEC) for these circuits. The NEC stipulates that at least two 20-amp small-appliance branch circuits must be provided, with the 1500 VA load being essential for accommodating typical kitchen and dining area equipment.

The purpose of this calculation is to ensure that there is enough capacity to handle the electrical load from appliances like toasters, coffee makers, or microwaves, which are commonly used in residential settings. This value is intentionally chosen to ensure safety and efficiency in residential wiring. Setting the load at 1500 VA thus prepares for typical scenarios, and reinforces the focus on simplifying circuit design and ensuring compatibility with standard appliances used within these spaces.

Understanding this helps in both compliance with regulations and in effectively managing electrical loads in residential wiring systems.
