I have to install an ATS for an already installed generator. They didn't drive a ground rod so I thought I would have to.
In talking to the inspector, I mentioned the rod and he said if I could get to the house rod or the GEC, I could just tie on to that and be done with it.

Turns out the inspector doesn't work the area anymore where the install is.
The other inspector is totally different than the one I talked to. So I don't know if he will accept "tapping/bonding" to the original rod or not.

Will they accept this for any of you guys that have installed gennys?

I would assume you would want to tap into the existing gec at the ATS, that is where it is going to be bonded. Does that make as much sense to you as it does to me?

Around here don't have to install rod for the gen. As long as grounding is up to code for the transfer switch all is good. Ground rods and water ground go to the TS.

Not really since this ATS isn't being used as the main disconnect. It's just an ATS pre-wired with a load center. It will be mounted inside beside the main panel, and will be treated as a sub panel. There is a 4-wire feed, so the EGC will be what bonds the ATS.

Whatever I do as far as the rod or tapping outside, all I have to do is connect it to the bond lug at the genny.

Id doesn't matter as far as theory goes. I was trying to explain it in a odd way, I guess. Like the video said, you don't want differing paths to earth within your own grounding system, it creates a potential between the two earthed points.

what is the difference between installing a rod at a xfer switch and installing rods at a detached structure?

I'm probably missing how the two things are related.

Anyway if the neutral is not switched it is not a sds (250.30 inf) and needs no separate ground rod. There is no code preventing you from adding one though. If it is within 6ft from the first they must be bonded.
