Final answer:
A 20-ampere-rated branch circuit is required for the laundry area, serving only its receptacles to prevent electrical system overload.
Step-by-step explanation:
A minimum of one 20-ampere-rated branch circuit shall be provided for receptacles located in the laundry area and shall serve only receptacle outlets in the laundry area. This requirement is to ensure that your laundry area has a dedicated circuit to prevent overloading of the electrical system, which can pose a safety hazard. Laundry appliances, like washing machines and dryers, often require more power and hence a higher amperage circuit compared to what is needed for regular household receptacles.
