The minimum number of circuits typically required for kitchen appliances is two. This requirement is mainly driven by the need to handle the specific power demands of various kitchen appliances safely and effectively.

In most electrical codes, such as the National Electrical Code (NEC), it's mandated that at least two separate 20-amp circuits are dedicated to serve kitchen countertop outlets. This ensures that high-wattage appliances, such as toasters, blenders, and microwaves, can operate simultaneously without overloading any single circuit. By distributing the load across two circuits, the risk of tripping the circuit breaker or creating unsafe conditions due to overload is minimized.

Moreover, having more than one circuit allows for better flexibility and convenience when using multiple appliances at the same time—important in kitchen settings where multiple tasks are often performed simultaneously. Additionally, some codes suggest separate circuits for major appliances like refrigerators or dishwashers, further supporting the need for a minimum of two dedicated circuits for general use on the countertops.
