The transformer is 480/240 delta/delta. I am asking about equipment ground.
What I am hearing (reading) is that the equipment grounds for motors and other equipment should be connected back to the main system ground....
Correct me if I am wrong....else, thanks for your help.
Does a 240V delta load from a transformer 480/240 3W transformer need to be grounded? I am looking for code references if possible (I can find wye references, but not for delta secondaries).
