Question: 1 / 400

How many inches above the adjoining grade must the support for equipment and appliances extend?

1 inch

2 inches

3 inches

The requirement for the support of equipment and appliances to be elevated above the adjoining grade is a safety measure outlined in the International Mechanical Code. By specifying that the support must extend at least 3 inches above the adjoining grade, the code aims to prevent potential water intrusion, which can lead to equipment damage and increase the risk of electrical hazards.

This elevation minimizes the likelihood of flooding or standing water affecting the equipment, ensuring that the mechanical systems operate effectively and safely. A support height of 3 inches strikes a balance between being high enough to mitigate these risks while still being manageable for installation and maintenance.
