I am installing a 20KW Nexus with an RTSD ATS with load shed. I ran all of the control wires EXCEPT the "0" (Zero) wire. I now understand this wire is required for the Load Shed module DC voltage.

There is no way I will be able to run another wire to the generator. Are there any alternatives? Looking at the 20KW schematic, the zero wire is tied into the same ground as everything else in the generator... both AC and DC. If this is the case, couldn't I just jump the zero wire in the ATS to ground in the panel? I am looking for any alternative rather than running another wire. Any help would be greatly appreciated!

Thanks!

That will work but there may be a code/warranty issue here.

I don't know where that wire goes, but consider what a nearby lightning hit might do. That could easily change the ground potential and thus possibly mess with whatever the "0" wire is connected to.

You already have the utility/gen. neutral in the transfer switch. You can use it.

Thanks for the replies. I don't have much choice than to jump to the ATS ground block. I will keep my fingers crossed....
