[QUOTE="Tim Duffin, post: 97543, member: 400"] Re: Experience running off diesel generators Sizing a generator is not hard. They are equivalent to what you would need from house power. If you have a 3 phase distro, or split phase distro, you will simply set the generator to whatever you need. Please note that you cannot simultaneously run 120/240 and 120/208 on the same genset. You have to pick one and stick with it. I own my own generator since I kept getting promoters who would save money by getting the smallest, weakest unit possible for shows. Now, they either rent my generator or I won't do the show. It is also advisable to get a generator sized 140% of your system load or you will get "surging", where the generators engine can't keep up with the dynamic load and starts to rock back and forth to the music...which is very bad. So, I have a distro that has a 3phase 100A main breaker. Coincidentally, that matches a 75KVA generator (which also has a 100A main breaker) and that works perfectly. At one time in the past, I tried to connect a huge amount of amps and equipment to a tiny 35kva generator, and I stalled it. It is always better to oversize your unit. [/QUOTE]
