Hey everyone! Thanks for all of your input on this thread!
I'm happy to report that the shoot went off without incident, as far as electricity and lights are concerned; no shocks, no arcs, no green flames . Fortunately (for me) the temperature was consistently below freezing for the entire week so we didn't have standing puddles or slush to worry about. We did have a lot of wind and snow, but between the cello, sealing our connections with garbage bags and electrical tape (a method we started calling "Tootsie-Rolling"), and using extra sandbags and safety lines, we were able to neutralize these safety concerns.
We grounded the generator and the light stands to copper spikes that were pounded into the frozen ground by a local electrician who used an auger to get the holes started. We ran 14 gauge wire from the light stands to the grounding spikes. The stands were placed on rubber matting and plywood.
The generator we were using for most of the production was a Honda EU 6500is which we often used to power all three HMI's. The 2.5 was powered through a three-prong twistlock 30A outlet on the genny. We plugged in a twistlock to bates adapter and ran bates for the 2.5. The 1.2's were powered by the two 20A Edison courtesy outlets on the genny. The only time the other generator (Honda EU 2000i) came into play was on a day when we wanted the 2.5 and a 1.2 on opposite sides of an active snowmobile path, which we couldn't run cable across. We didn't use any GFCIs.
One thing i'm not sure of is whether we had power factor corrected ballasts for the HMIs. How can you tell? Does "EB" stand for "electronically balanced" or something? The ballasts we were using looked similar to these:
Does the One other question that came up was "Is it safe to refuel a generator while it is running?" We had opposing viewpoints on this. Let me know if I missed one of your questions with this response.
Thanks again, everyone!
