    IT configured back-up genny

    Am installing a bqckup genny in a house with a TNCS supply. Its will be in use 6 to 8 hrs/year (average yearly DNO outages). My question revolves around the genny,s supply .I see more advantages for the homeowner in having an IT configured genny than a TNS configured genny. Am I missing something?
