How high above the floor level should the bottom edge of the SEP cabinet be?

The bottom edge of a Service Equipment Panel (SEP) cabinet should typically be positioned 40 to 48 inches above floor level. This height range is established to ensure safety and accessibility for individuals who may need to operate or maintain the equipment, as well as to adhere to building codes and electrical standards. This positioning also helps to keep the panel above potential flood or water issues in some areas, while still being reachable for authorized personnel.

The specific range allows for some variability based on the specific environment, the code requirements in different regions, and the preferences of users or electricians. Therefore, choosing 40 to 48 inches strikes a balance between usability, safety, and compliance with the necessary regulations.
