What is the minimum length of cord required for electronically operated kitchen waste disposers?

12 inches
18 inches
24 inches
30 inches

The correct answer is: 18 inches

The minimum length of cord required for electronically operated kitchen waste disposers is 18 inches. This specific length is established to ensure that the cord can be safely connected to a power source while allowing adequate slack for safe and convenient operation. The 18-inch requirement helps minimize the risk of cord damage or strain on the connections, which could lead to potential hazards such as short circuits or electrical fires. Furthermore, having a cord of this length can facilitate proper installation practices, ensuring that the disposer can be easily connected while maintaining compliance with electrical safety standards.
