A 3 phase dry type transfer (15 kva)with a delta secondary (480 volts)the connected load is one 7 1/2 HP pump motor 1 1/2" miles from the transformer. Four #1's to run in PVC.(Area is very wet)
Questions: 1) should the secondary of the transformer be grounded or should the secondary be remain electrical isolated from ground? 2) How should the secondary be grounded? 3)Were can I find this information in the NEC? 4)Explains the reasoning for grounding?
Thank you
