How much space is required in front of a free standing Y-connected HRG for a 4160V system (Condtion 2 working clearance)?
Looking at the schematics I see a 2400V:120/240 CPT; however, the primary connections are H1-transfomer neutral and H2-ground. There is no line voltage in the free standing structure, thus it falls under Table 110.26(A)(1) Condition 2 0-150 due to the control voltage (125VDC) involved.
Is my understanding correct and the end user should not question the clearance not meeting code?
