Which appliance is permitted to have a 24" cord with attachment ground plug?

The combination range hood/microwave is allowed to have a 24" cord with an attachment ground plug because it is considered a portable appliance. According to the National Electrical Code (NEC) and the associated local regulations, certain kitchen appliances are designed to be easily installed and removed, thus enabling the use of shorter cords.

This provision is particularly pertinent for devices placed above a cooking range or in areas where length constraints exist, such as above countertops. The attachment of a ground plug ensures safety by providing a path for electrical current in case of a fault, preventing shock hazards. Appliances like electric ovens and dishwashers typically require hardwired connections due to their power demands and operational nature, which differ from those of a combination range hood/microwave. Refrigerators, while sometimes having a shorter cord, do not typically utilize a 24” cord with an attachment ground plug in compliance with electrical codes.

Understanding the specific requirements for each appliance's installation helps ensure both safety and compliance with local electrical regulations.
