Get three electricians in the room.... It 6'-7" "from the center of the grip of the operating handle...when in highest position." Happy Holidays.

Can't recall the millimeter conversion off the top of my head... Oh, wait! My tape is in inches, anyway. Minimum height is a judgement call. Your judgement and the AHJ's judgement. Look around. Is there anything that can/will interfere with or damage the switch? Sprinklers, pallet-jacks, foot traffic? Next thing i look for is "where is it the most functional"? Visible and reachable is more valuable than trying to use a short piece of conduit and wire. i also look at importance... If there is one switch that controls a high hazard source, for instance... You want it in a prominent location. A switch that may need to be operated in a emergency shouldn't be mounted too low. 3' or higher, for sure. The closer to eye level, the better. It's always a challenge looking for the best arrangement of equipment with complex systems. One thing i try to do is visualize the space and arrangement from the perspective of entering the area. What if somebody is not too familiar with the equipment and it's an emergency? Can they spot and operate the swiches they need easily? i have had some very good solutions appear from this exercise over the years. Solutions that my brain didn't see from "straight on". Hope you find the right mix, Bob.

I recall that there is no minimum height in the Code for your application.

So its an interesting mix, 3 are just to cut the generator run time for the diesel generator. I am trying to find the allowable range for switch heights for all the gear. Seems the upper limit is about 6' but I am unsure on the lower limit. Any ideas? Thanks, Bob Ellison
