Have a unique situation many someone could help me with. Have a 600 ampsingle phase service 120/240 volt. bld also has a 200 amp 3 phase 3 wire delta 240 volt center phase grounded. we set a 200 amp transfer switch for 3 phase and 600 amp single phase for single phase. generator is 3 phase 120/240 3 phase y output.( we changed taps up to 240 volt). inspector violated because if someone was working on equipment and gen started, center phase would now become hot, we offered to mark all equip with plaques but was rejected. the equipment will run on either 120/240 3 phase or 240 volt to ground or phase without problem. inspector could to me code article I violated. any help?.these problem is only present if gen set is runningotherwise both systems are isolated.
