Electrical Panel Height From Floor

I understand some of the electrical panel clearance rules like 3 feet clearance in front 6 5 feet minimum height and 30 inches workspace left to right so 15 left and 15 right from centerline.

Electrical panel height from floor. The electrical equipment itself may have a height that is less than 6 1 2 feet but if it is mounted so the top of the equipment is higher than 6 1 2 feet the minimum working space. Also the maximum height of a circuit breaker must not exceed 6 7 above the finished floor or working platform per nec 240 24. Apparently the general answser is no minimum height but a 6 7 max height to the top breaker which if higher must have a permanent step etc. But i haven t been able to find anything stating if there is a minimum clearance from the floor required.

The minimum height shall be to the top of the equipment. Height for breaker panels returned a surprising number of forums addressing this very question which i hadn t expected. This workspace shall be clear and extend from the floor to a height of 6 1 2 feet and shall not be used for storage. The circuit breaker at the top of the box may not be higher than 6 foot 7 inches from the floor.

A permanent platform must be below the panel box if the top circuit breaker exceeds this specific height. Nec 240 24 e states that in dwelling units dormitories and guest rooms or guest suites overcurrent devices other than supplementary overcurrent protection shall not be located.
