A receptacle under the kitchen counter for a dishwasher is generally allowed to be connected to how many small-appliance branch circuits?

A receptacle under the kitchen counter for a dishwasher is generally not permitted to be connected to any small-appliance branch circuits. The National Electrical Code (NEC) specifies that the two small-appliance circuits required in a kitchen must serve outlets for countertop appliances and should not supply power to permanent appliances like dishwashers.

In a typical kitchen layout, the small-appliance branch circuits are designed for flexibility and convenience, allowing multiple countertop appliances to be used simultaneously. However, dishwashers are considered fixed appliances and are typically installed separately, requiring their own dedicated circuit to handle the electrical load and ensure safety. This distinction is important for both code compliance and to prevent overloading the small-appliance circuits that are meant for more transient, portable usage rather than fixed appliances.

The restriction promotes safe electrical practices by preventing the potential for overloading the circuits and minimizes the risk of tripped breakers or fire hazards.
