I'm hoping to find some guidance regarding generators. Most everything I can find regarding generators deals with portable or back up but I'm working overseas in an environment where they are essentially prime power. I've tried to research this but honestly the more I dive into it the more I confuse myself. I'm hoping some of you can provide me with some clarity.
I'll give a direct example and then extrapolate out from there. There is a 120 kW generator being brought on line. There is a neutral to ground bond in the gen. it will feed out via G cable and a pin and sleeve connector to essentially a spider box. Out of that spider box are more pin and sleeve connectors and more G cable going out to the various loads.
The simple question is this: does this generator need a ground rod? (For what it's worth the gen will not actually be in touch with the earth- it sits on 4x4s inside a containment bladder to catch fuel spills.) I've read that it does, I've read that it does not. The way that I'm looking at this is that I'm not sure what the ground rod will add. But I've been known to be wrong before.
Any opinions you have would be appreciated (well, opinions about the grounding thing- if you're opinion is that I'm funny looking and listen to bad music, well those wouldn't be appreciated...)
