Final answer:
The space required between the base of tabletop equipment and the tabletop is at least 6 inches, which is a standard sanitation requirement for ease of cleaning in a kitchen environment.
Step-by-step explanation:
When installing tabletop equipment on legs, the space between the base of the equipment and the tabletop must be at least 6 inches. This requirement is often established for reasons of sanitation and ease of cleaning. A minimum clearance of 6 inches helps prevent the accumulation of food particles and debris, and allows for easier cleaning underneath the equipment, which is essential in maintaining a healthy and safe kitchen environment. Nineteen out of fifty states specify the 6-inch clearance in their foodservice codes, reinforcing this as a standard practice.
