What is the minimum number of branch circuits required to serve receptacle outlets located in a laundry area of a dwelling?

To serve receptacle outlets located in a laundry area of a dwelling, the requirement is for at least one dedicated 20 AMP branch circuit. This guideline is rooted in the National Electrical Code (NEC), which specifies that laundry areas must have sufficient power capacity to handle the electrical demands of washing machines and other equipment often used in that space.

A 20 AMP circuit is necessary because it can sustain a higher load compared to a 15 AMP circuit, which is crucial considering that laundry appliances can draw significant power, especially when operating concurrently. The dedicated circuit ensures that the electrical needs of the laundry area can be met without overloading the system or risking electrical safety.

While other options suggest lower amperage or different circuit configurations, they do not satisfy the typical load requirements for laundry appliances, which is why the specification for a 20 AMP circuit is not just beneficial but essential for safe and effective operation.
