I have 15KV primary - 480Y/277V secondary transformer and then I have a fence around it. I only have 22-3/4" of space on each side of the transformer and 3'-0" on the back and 7' on the front. the fence only has one door in front of the transformer.
Q1: where in the NEC are the requirements for space clearances on the sides and back of a medium voltage transformer? i have heard it is 2 feet on the sides and on the back but haven't been able to find this in the NEC.
Q2: Are the clearances above ok for egress? (NFPA 101) i have heard this is 36" but haven't been able to find this either.
