Why does my UPS keep tripping a circuit breaker on my main board?
My UPS keeps tripping my mains (at least one of the circuitbreaker it is connected to). Regardless of which plug I use in the wall, the moment i switch on the UPS it trips my mains board. The UPS functions though as I am able to connect devices and use the battery power -- as long as the mains arent connected to the UPS. Faulty board inside the UPS? Could it be the circuit breakerinside the UPS which may be faulty?
