My electric is supplied by overhead cables, and power failures are not rare. The electric comes into the detached garage, though a mains breaker then fed to the house via an armoured cable, into another breaker box. When the power fails, every so often it will trip the mains breaker in the garage or the house. When it is in the house it is easy to reset, however as we have electric doors to the garage it is a bit of a pain having to manually open the garage doors, then go through the reset procedure to get them working again. What I would like to know is what is the likely cause of the mains trips operating, I don't know if it is when the electric cuts off or returns, as it usually happens overnight. Is there anything I can or should do to stop this PITA occurrence?
