How many 20A small appliance branch circuits are needed in a dwelling unit kitchen?

In a dwelling unit kitchen, the National Electrical Code (NEC) requires that at least two 20-ampere small appliance branch circuits be provided. This requirement is set to ensure that there is sufficient electrical capacity to support the various appliances that are typically used in kitchens, such as toasters, microwave ovens, and coffee makers, among others.

Having two separate circuits helps prevent overloading a single circuit, which could cause overheating and potential fire hazards. It also allows for a more efficient power distribution, ensuring that multiple appliances can be used simultaneously without tripping the circuit breaker. This design consideration is essential for safety and convenience in the kitchen environment.

The code specifically states that these circuits must be dedicated to the kitchen and cannot be used for other purposes, reinforcing their importance in providing reliable power for kitchen activities. Therefore, the requirement for two 20A small appliance branch circuits ensures compliance with safety standards while promoting effective kitchen operation.
