3. What Is A Load Bank? Load Banks are devices designed to provide electrical loads for testing power sources such as for testing power sources such as Generators and Uninterruptible Power Supplies (UPS). (Dummy Load) Normal/Emergency Load s Load Bank

4. Why Are Load Banks Necessary? Maintain reliability of the Emergency Power System by testing of the engine generator (s) under load. by testing of the engine generator (s) under load.
