Today we tapped a 480v 3 phase line that is fed from a generator. The tap goes to a 480v primary / 120/208 secondary transformer. There was no neutral on the 480v side. Now when on generator power we have lights ( MH ) flickering and going off and on. When we switch back to utility no problem. Generator running fine only 37kw load on a 100kw generator. What could be going on? Transformer was fed from same switch gear as the other 480v line.
