For built-in dishwashers, what is the minimum cord length requirement?

1 foot
2 feet
3 feet
4 feet

The correct answer is: 3 feet

The minimum cord length requirement for built-in dishwashers is established to ensure safe and functional installation. In this context, a cord length of 3 feet provides adequate wiring allowance for both connectivity and accessibility. This length allows the dishwasher to be plugged into the outlet without causing strain on the cord, which can occur if the cord is too short. It also aids in meeting the NEC requirements that prioritize safety and minimize the risk of electrical hazards. In practical terms, a 3-foot cord length accommodates various installation scenarios, including enough reach for the appliance to be moved out slightly for service or repair without needing to disconnect the electrical supply. This specification underscores the importance of balancing safety and convenience in residential electrical applications.
