[QUOTE="phil d, post: 482007, member: 27126"] assuming you can get access to the outgoing or load cables from the control setup, try disconnecting the fan from here and see if the starter goes in without tripping the RCD in the house, if this works then connect a normal 60W lamp across the load terminals and try again, if this stays in you have a fault on the motor, if it trips out then I'd be checking to see if you have somehow got the neutral and earth crossed somewhere. You can measure between L and E and it won't trip the RCD, but put a load on it and it will, it may seem obvious but it's worth checking. [/QUOTE]
