Here's something I've been wondering about...during my days working at a rental house I was always told that when it came to balancing loads on a generator, no more than 50 amps apart was recommended - that came straight from the genny manufacturers we dealt with. I never questioned it and have always applied that formula anytime I've been in charge of a generator on set.
That being said, I've worked a number of big shows with genny ops, and I've noticed that they don't seem to apply that same formula - for example, there have been times when we would have only an Arrimax up on lines 1 and 2, and absolutely nothing on 3, and they never seem to think that that's a concern. The frequently don't even bother to let us know we need to balance until we're over 100 amps apart. I figure the genny ops know what they're doing, do they know something I don't? These are different gennies, typically bigger tractor mounted plants...is that the difference?
I'm working as a best boy on a feature right now with a Litepower 500 amp, just want to make sure I'm doing the right thing - Guy Holt, would love to hear your feedback if you're around.
