Excluding exceptions Article 240.24 and other areas of the NEC state the highest position for the center of a switch handle 6 ft 7 in above the working platform. Is there a minimum height for a main disconnect switch?
I have come across a 600 AMP, 240 VAC main building disconnect switch on the outside wall where the center for switch handle is about 3 ft above finish grade. I cannot find this height as a Code violation. However, directly above the main disconnect switch is an set of stairs which does violate Article 110.26 (A) (3) for a work space height of 6.5 ft or the height of the equipment, whichever is greater.
