Did you know that your emergency power system has one crucial point of failure that is completely independent of your emergency generator? If this component fails, your generator will not even know it needs to start!
This single point of failure is called an ATS or Automatic Transfer Switch.
An ATS monitors the electrical power from your utility and, when it detects a power grid failure, it signals your emergency generator to start. It then switches your facility from utility power to generator power. When it detects that the utility power is restored, it switches back to the utility and signals the emergency generator to shut off.
Although it is a critical component in your emergency power system, ATS maintenance is often neglected for various reasons. However, this neglect will eventually result in a failure to transfer power when you need it most!
