How many 20A branch circuits are required for laundry outlets in a dwelling unit?

In a dwelling unit, the National Electrical Code (NEC) specifies the requirements for laundry outlets, which are typically located in laundry areas or rooms. The NEC requires at least one dedicated 20A branch circuit for laundry outlets to ensure safe operation and enough capacity for the equipment typically used, like washers and dryers.

Laundry areas often have machines that operate simultaneously, so a single 20A circuit is designed to provide adequate power for a washing machine. However, code also anticipates that, for greater convenience and flexibility, additional circuits might be beneficial, particularly if both a washing machine and an electric dryer are installed in the same area.

The reasoning for having only one dedicated 20A branch circuit reflects both practical considerations and efficiency within standard design practices. Therefore, the requirement is fulfilled by one dedicated circuit, which allows compliance with safety regulations while advocating effective resource usage. It is important to consult the current NEC and local amendments to verify if additional circuits are warranted based on specific equipment or situations present in the dwelling.
