What is the maximum cord length allowed for built-in dishwashers?

4 feet
5 feet
6 feet
7 feet

The correct answer is: 4 feet

The maximum cord length allowed for built-in dishwashers is 4 feet because the National Electrical Code (NEC) mandates that the flexible cord used for these appliances must not exceed this length. This restriction is in place primarily for safety reasons, aiming to prevent potential hazards that could arise from longer cords being subject to wear, damage, or creating tripping hazards. Additionally, shorter cords help to ensure that the appliance is installed and located properly, reducing the risk of overextending or creating situations where the appliance could be improperly connected to an outlet. Thus, adhering to this maximum length is important for both the safe operation of the dishwasher and compliance with the NEC standards.
