Let me first say hello to everyone. I work in standby and prime power generation so my NEC code knowledge is below average, but I know enough to NOT to be dangerous.
Recently I purchased a 1950's home and of course #1 thing was to upgrade the existing 60A to a 200A service. I also added a 45Kw standby generator.
Upon inspection by an independent inspector (PA stinks!), he told me I have "Neutral Issues" I need to square away. He wouldn't tell me any more. So I consulted my NEC book and I can not for the life of me figure out where I screwed up. Here's what I got:
200A service from Meter base to a 200A disconnect where the Neutral and Ground are bonded (Ground comes from the rod beside the foundation), Then on to a 260A automatic transfer switch (4 pole neutral switching contactor), Then to my 200A panel for the home (which is neutral isolated). What kind of "Neutral Issue" do I have? I can't for the life of me figure out what the heck he meant.
The generator is NOT neutral isolated because the ATS switches the neutral from the main disconnect....This is the only "Grey Area" I can figure on..
