Bonding The Neutral On A Stand-Alone Generator System.

[Seven-Delta-FortyOne]

There is no grid power on site at all.

There is a generator in a shed, and a 200 Amp main panel about 120 feet away in a separate building.

The GenSet has a bonded neutral.

If I install a non-fused disconnect in the shed where the generator is, do I......

Bond the neutral at the main panel?

Bond it at the disconnect? It isn’t set up for that, so I may need to get a SE Rated panel instead.

Or, bond it both places? 250.30(A)1 exception 2?

Conduit is PVC.

Thanks for any and all assistance.

Here’s the inside of the disco.

It says it’s suitable for service equipment when a neutral kit is installed.

I guess that’s how I have to do it, huh?

Forgot the pic.

Are there separate neutral and EGC in the feeder?

Can be

i can pull it either way

if I bond at the main, I won’t have to pull an EGC

Agreed. Bond at both ends; earth is not considered a parallel pathway.

So if I bond at the disco, and bond again at the main, and just pull 3 conductors, I should be good.

Generator has a ground lug, but the diagram just shows it going to a ground rod.

I was going to set 2 rods at the panel, and another and the genny.

So I’m not seeing the need for an EGC

Presuming 1ph, yes.

Me too neither.
