I have a 480Y/277V ATS that falls under condition 3 (Exposed electric equipment on both sides of the working space) of Table 110.26(A)(1) Working Spaces. I have 47-5/8" from the cover of the ATS and the cover of the adjacent switchgear. The handle to open the ATS sticks out a couple of inches from the ATS enclosure. Am I in violation of 110.26 since I need 48"?
110.26 A (1) Working Spaces states,"....Distances shall be measured from the exposed live parts or from the enclosure or opening if the live parts are enclosed."
The part that confuses me is "or opening if the live parts are enclosed." Does that mean I can measure from the wall of the enclosure with the door open? Thank you for your input.
