A garbage disposal in the kitchen of a residence is provided with a type SO three-conductor cord that is terminated with a grounding-type attachment plug. This connection method is permitted where the ___. I. receptacle is readily accessible II. receptacle is located to avoid physical damage to the flexible cord III. receptacle is accessible IV. length of the cord is not less than 18 inches and not over 36 inches. Which of the following sets of conditions apply?

• A. I, II, & IV only
• B. I, II, & III only
• C. II, III, & IV only
• D. III & IV only

Answer: (C)

When a garbage disposal is connected with a type SO three-conductor cord and a grounding plug, the allowed setup centers on keeping the cord safe and the connection serviceable. The receptacle should be placed so the flexible cord isn’t subject to damage—think avoiding pinch points, doors, or drawers that could snag or crush the cord. It also needs to be accessible for service or unplugging, and the cord length must stay within a specific range to keep the installation neat and reduce strain. The rule that would require the receptacle to be readily accessible isn’t applied here, since under-sink installations often place the receptacle out of immediate view (inside a cabinet) while still being accessible when needed. So the permitted conditions are that the receptacle is positioned to prevent damage to the cord, is accessible, and the cord length is between 18 and 36 inches.
