Code referenced 2011 NEC.
Q1) Table 110.34(A): Does condition 3 apply if you had one equipment operating at above 600V and another in front of it operating at below 600V?
Q2) I have a 34.5kV line which feeds a 34.5kV main CB, which feeds a 34.5kV to 480V MV Transformer, which feeds a 480V main CB and distribution sections. I am showing working space in front and behind the 34.5kV equipment. Would anything be required on the side of the equipment?
