[QUOTE="Eric Cagle, post: 5693, member: 277"] Can anyone tell me if there is a problem running two seperate generators for power amps, one for each side of the stage? I had an emergency situation happen once that required me to run two smaller generators to get enough power for an event when the large generator I had reserved went down prior to being delivered to me. I used a generator for stage left and front of house power and used the other one for stage right power. I used a isolation transformer on the XLR line from front of house to the stage right amps. Fortunately this was a DJ gig so there was no band and no backline. A third generator was used for the lighting and fog machines. This was on top of a concrete parking deck. I did not tie the grounds together and there was no place to get an earth ground unless we ran a line three stories down and across the street. There were no ground loops and nobody got shocked but I was concerned even though I had called an electrical engineer friend of mine for advice. Any enlightenment would be appreciated. [/QUOTE]
