In both cases, the over-heating of the generator makes the man- ual-rearm safety thermostat intervene, which is installed on the wall of the generator. As a consequence, if there are no generator thermostat interven- tions, all corrosion phenomena can be excluded and no inspec- tion or additional action is necessary.
