maximum height of Main Breaker in panel board

[Mike4510]

We have a number of panels that are mounted above transformers. The panels are brought to the front. However the height if the switch on the main breaker is just over 7 feet. I understand NEC 240.24 A says 6'-7". Is there any exception for a utility?

If the breakers are on the utility side of the service point between it and the customer, then NEC does not apply.
If the load on the panels is entirely equipment on utility property used for utility purposes (i.e. production, distribution), then the NEC may not apply either.
But if not NEC, then usually the utility will choose to comply with NESC or better under their internal safety rules.

If you are in a situation where every inch matters, the official rule is that the center of the grip of the handle in its upper position needs to be no higher than 6'-7" above finished grade/floor/platform.


If your disconnect is not required to be readily accessible, it is OK to elevate it.

The understanding is that you would use either a portable ladder, or a hook stick to operate it. Utilities commonly use hook sticks to operate elevated switches, that are intentionally lifted out of reach of the general public.
