I statrted this thread some time back and wanted to revisit because to day we went to make our recomended changes but was called offy HO and oroiginal generator EC. We were originally called to do service work on a generator and in the process I was called about my opinion on the following install. An existing residence with a 400 amp service had a 60 kw generator with 400 amp ATS installed. The new ATS was fed from two existing 200 main disconnect panels which in turn feeds two 200 amp house panels. My problem was a single 400 amp "load center" ATS being fed from two separate 200 sources. The installer called it a parallel installation with conductors properly fused at 200 amps each. My thought is that there is the potential of the entire house load chosing only a single set of conductors back to utility. If the entire load stays under 200 amps then in theory the install works (theory, not code, IMO). HO and EC agreed that there was no concern and the existing install should be left alone. Am I correct? Or is this ok and I am missing something.
