Forgive me if this has been discussed before, so here goes:
A few weeks ago their was a photo shoot in the main space here on campus. Professional local film people were hired to do the job. Part of what they did was tie in directly to our company switch so they could use their own distribution equipment to power the 6K spacelights w/ 60 amp Bates connectors that they brought in. (It was quite a weekend, we ended up dumping 54K of pure white light on to a 16'x16' space, quite a different world for someone who had done primarily theatre, such as myself)
So heres the question. When they tied in their feeder, the hots and neutrals were all 2/0, but the ground was #2. Is this allowable practice? For some reason I thought this was frowned upon? I'm only ever been used to seeing a five wire feeder system where all 5 cables are of the same gauge. I should also add that these five cables had been loomed, and looked like they had been for a long time. (not that that is bad persay, but it does derate the conductors, which always has to be considered)
On a related note regarding cam-lock orientation: Their distro had males for the hots and neutral, and a female for ground, instead of all five being males, or the hots males with neutral and ground being females. Another variant in the mix.
