Hi Micmann
i wonder if this is an old 'customer owned' service lateral you've run into
if so, why not get a ruling from the local AHJ?
just a thought, maybe that 'existing' term might work for you to where you end up with 2--400A service rated T-switches w/ the control side in parrallel out to Gennyzilla, and you don't need to pitch for a 800A bid breaker main...?
