P S What happen to dbbrown? I learned a lot from this guy. Very knowledgable.
it would depend on what type of bank it is. iff its a y-y then it will not backfeed (unless theres a generator hooked up) because all transformer coils are grounded, but as soon as you throw in a delta, high or low side everything is hot. might not be full line voltage but it will still be hot because there is not a ground on all coils
