What is the required clearance for electrical panels from the floor?

The required clearance for electrical panels from the floor is at least 4 feet or 48 inches. This regulation is in place to ensure accessibility for maintenance and operation, while also providing a safe working environment.

Having electrical panels elevated to this height helps prevent accidental contact with individuals who may be walking or working around the area. It ensures that those servicing the panels can do so without having to kneel or crouch, which reduces the risk of injury as well as facilitates easier access to conduct inspections, troubleshooting, or repairs.

This standard is often outlined in the National Electrical Code (NEC) and many local building codes, which emphasize both functionality and safety in electrical installations. The other options either exceed the necessary height or do not meet the minimum requirement, thus making them noncompliant with the standards governing electrical installations.
