So far as I understand they lost both main AC busses. They did have generators available (there’s a picture of the system synoptic somewhere by the beginning of the post) but nowhere to connect them. Given the scenario, I don’t think that your suggestion would have made any difference. Hell even the RAT apparently didn’t engage to a bus! Is that bit of info confirmed? Usually the RAT feeds an essential bus or something different from the main busses. Having the RAT deployed but not powering its bus(ses) would be a true kick the nuts... Electrical system should’ve gone completely bat !!!!! crazy somehow for this to happen
