What type of receptacle is specified for the Frosty machine in the Wendy's Restaurant?

The NEMA 15-30 receptacle is specifically designed to accommodate devices that require a 30-amp rating, which is often needed for equipment such as commercial appliances like the Frosty machine in a Wendy's Restaurant. This type of receptacle can accept both 15-amp and 30-amp plugs, allowing for versatility in connecting different types of equipment.

The requirement for a receptacle with a higher amp rating is essential in commercial environments where machines may draw significant power during operation. The Frosty machine, as a commercial appliance, likely has a higher electrical demand, thus necessitating the use of a NEMA 15-30 receptacle to ensure safe and effective operation.

In contrast, other receptacle types mentioned do not meet the specific electrical needs required for such equipment. The NEMA 15-20 receptacle is suitable for lighter loads, typically used for general-purpose outlets. The NEMA 30-50 receptacle is designed for much larger equipment and would be unnecessary for a Frosty machine. Lastly, the NEMA 5-15 receptacle is standard for household applications with lower amperage, which would not suffice for a device requiring a 30-amp connection.
