People that have done outdoor parties with no power, what have you used?

I mean like you said, all you might need is like 30a. You realize thats only 3600 watts @ 120v, right? 10,000 watts seems like a little overkill, no? A lot of portables around 3-5kw range come with multiple 120v 20a outlets all protected on their own breaker. No need for distribution panels and the time and money that goes into that.

As far as grounding goes, both hot leg coils off the generator are center tapped at a single point and then bonded to the frame of the generator, from the frame of the generator you usually get your ground (could technically come off the center tap too), and from the center tap you get your neutral. You won't get a better more stable ground if you bond it to the earth. Your gear is no better off. This is basically how 1 phase transformers for houses are grounded too, except instead of bonding the hot legs that are center tapped to a frame, it goes straight from the center tap of the transformer to the earth. The earth now becomes a big conductor back to the source. In theory if you have a large enough fault to earth and the service neutral is cut or somehow not part of the fault, you could still get a short circuit and a breaker/fuse could trip/blow since the earth is now a conductor back to the source. Under normal circumstances, most of the current from a ground fault short circuit is going to pass thru the service neutral since that is going to have the least resistance.

Anyways, GFCI or even no GFCI's, in a cord and plug application like this, it just doesnt make sense to make the earth part of the grounding system for safety, and as for the protection of gear , in this situation, it doesnt even impact it, as it's almost unrelated, as an earth bond and gear ground are different. I mean even OSHA says you dont need to do this.

I would get a 10K watt generator at minimum. You will have to get a ground rod, copper wire (#6), and an "acorn" to properly ground it. Also will most likely need to make up a distribution box.

So I'd say it would be fairly loud. Not like earth shattering, but pretty dang loud.

Thanks for the info about the generators. I'll have to look into some that can produce that type of power.

I mean I'm looking at probably renting like CDJ 10002/2000s djm 800

PA speaker (no idea what size yet)
Amp, sub.

Lighting truss, and lights to go on it.

I can't let the cat out of the bag on the event I am throwing yet cause its confidential and I don't believe my co-founder friend would want me to spill the beans. But we are looking at some locations that will either end up at outdoor locations, some will be power provided, some won't possibly. It depends on how we plan it. I need to create a budget for either buying or renting the gear . I'm sure if I contacted these rental places they probably have a package deal that I could rent that would probably be fail safe, I'm assuming at least.

Regarding the generator, that was the only snag cause I'm not sure the places I could rent the DJ, sound and lighting gear would also have generators available. I thought I may have to rent something like that from a hardware place or something.

wicked overkill. I'm believeing thats like 3x the size he would ever need, I mean I dont know what his final load calculation will be, but thats like over 80 amps of power at 120v. Just as a reference for you, there are houses that have main services only rated at 60a. To the OP; most portable generators already have outlets set up for you, and are made so no supplemental grounding is needed, plug and go.
