The correct clearance required on the sides of an appliance for servicing is 24 inches. This distance allows adequate space for technicians to safely access the appliance for maintenance, repairs, and inspections without hindrance or risk of injury.

Keeping a minimum of 24 inches on the sides also ensures that there is enough room for the safe operation of tools and equipment required during service. Additionally, it helps maintain proper airflow around the appliance, contributing to its efficiency and safe operation.

The specified clearance is often dictated by building codes and appliance manufacturer's recommendations, both of which prioritize practical accessibility and safety.
