All documentation I can find (RFM supplement, MM & training material) states that the float system has dual power feed, with either power feed providing complete functionality of the Flotation System. To quote "The floats can either be activated automatically by two interconnected immersion actuators, one inside each main landing gear well or alternatively by pilot operated collective grip switches. The system has dual power supplies, the No.1 DC PRIMARY bus and the BATTERY bus; each is capable of activating the system."
Of course, if the system wasn't armed by the crew then they won't inflate.
AC generators will drop offline between 80% and 85% Nr when not WOW.
