I have a residential project that we did a while ago, and now we are adding a generator right before construction. They sent me the specifications for a 80KW generator with a NON service rated auto transfer switch that they want to use.
Right now I have the following setup:
A meter can feeding the ATS, then the ATS feeds the MDP panel UNDERGROUND which is inside, NOT immediately adjacent to the meter.
My question is, the feeder is outside the building the whole time because it is traveling underground. I think I should put a fused disconnect outside prior to the transfer switch correct? I know the easiest way would be for them to buy a service rated ATS, but I am trying to work with what I have already.
I added a quick sketch, see attachment .
Thanks
