What is the required height for equipment mounted on a slab or platform?

The requirement for equipment mounted on a slab or platform is often stipulated to ensure that it remains above potential water or liquid accumulation on the surface. This height can prevent exposure to moisture, which might lead to corrosion or other damage over time, thus ensuring the longevity and reliability of the equipment.

A height of 3 inches above the ground is a common standard in many practices, ensuring that equipment is sufficiently elevated to mitigate risks associated with flooding, spills, or condensation. This standard can vary depending on local codes or specific applications, but the 3-inch height is widely accepted as a minimum to achieve these objectives.

The alternatives provided reflect different height standards that are not as prevalent for general equipment mounting purposes. In some cases, heights greater than 3 inches might be used for particular applications or under specific circumstances, but these typically do not reflect the general requirement for most types of equipment.
