Automatic Mains Failure Panels are electrical source changeover devices usually for maintaining the essential services to a building or site where the continuity of supply is paramount. Buildings such as hospitals and computer centres are usually fitted with a standby generator which will take over the electrical supply if the electricity boards mains fails.

These amf panels monitor the loads via a three phase electronic measuring device and when the supply falls 'out of limits' the standby generator is given a signal to start. Once the Generator is running it output is monitored to ensure it is ready to accept load and then the building is changed over to the standby supply.
If and when the mains returns it is then automatically reinstated and the standby generator is shutdown, ready for its next call to duty.
The type of amf panels fall into three categories. Contactor type, Circuit breaker type and Motorised device type. You can follow the links on this page to learn more about the different type of panels.
