portable genset connection cabinet not a transfer switch bonding

[JHooser]

Hello All,

Been trying to mull something over and thought I would post here. I have a project in which we are installing a genset cabinet ahead of the main switchboard that has cam lock stab ins for dlo cable from the portable generator. I have installed a kirk-key system to insure that the main building service disconnect must be open before connection can be closed on the genset cabinet. Since the main service bonding for neutral and ground is at the main switchboard do I still need to bond the neutral and ground at the cabinet? I also have to ground the generator as well. Am I required to bond the neutral at this source? It seems as though if you tie all of this together, you are creating one giant grounding conductor with three different connections to Earth. A neutral doesn't truly appear until after you pass the main switchboard. I guess I am just not sure how this is really supposed to work. According to the code, separate earth connections do not constitute separate ground paths. Can anyone help shed some light on this for me?

Thanks,
Jonathan

Jonathan,

I am doing something similar right now at work, short story, use breakers that open the

neutral as well as the ungrounded conductors at each Kirk Key location.
