Scenario: lighting circuit serving several rooms including shower room. Shower room light switch also controls extractor fan. After a use of shower room in a morning (no other room lights in use), shower room lights and fan ceased to operate, since RCD had tripped.
I disconnected the fan at the fan, and disconnected the light switch, but still the RCD would not return to its 'on' position.
What could be the problem?
