We have received a shop drawing for a large control panel for some equipment, the drawing indicates 3- disconnect switches (rotary handles type) are mounted to the side of the control panel enclosure. However, to access the actual disconnect switch interior wiring it will be from the front of the control panel. My question, do I still need to have 3'-6" clearance Infront of these disconnect switches handles even though I don't think this will be a working space since the access to these switches will be from the front of the control panel it self? Thanks,
