We are working on an existing building, the transformer is 480 V, 215 kva and it is located next to the exist door, the inspector is asking to clear the transformer 3 ft. from the edge of the door frame, under code section 110.26 C 2A. But 110.26 Working Space "Working space for equipment operating at 600 volts, nominal or less to ground and likely to require examination, adjustment, servicing or maintenance while energized shall comply with the dimensions of 110.26 A 1 A2 and A3. My argument is that a transformer will not be energize if it need servicing, so the section will not apply. Does any body have an opinion.
