Load banks are devices designed to provide electrical loads for testing power sources such as generators and Uninterruptible Power Supplies (UPS). Testing with a load bank allows for a standby power system to be exercised under load to verify its reliability to perform in an emergency power situation. The load bank removes the risk to the critical facility load of total loss of power and loss of quality of power.

Another important reason to perform load bank testing is to prevent wet-stacking. Wet-stacking is a common problem with diesel engines which are operated for extended periods with little or no loads applied. When a diesel engine operates without sufficient load, it will not operate at its optimum temperature or peak efficiency. An engine experiencing wet-stacking will require more maintenance and performance will be compromised.

To help reduce the effect of wet-stacking, Cummins Sales and Service recommends the periodic use of supplemental resistive load banks to exercise the engine/generator. Applying an increasing load over a period of time until the excess fuel is burned off at or near rated output reduces the effects of wet-stacking. Conducting load bank testing in conjunction with periodic maintenance is recommended by the National Fire Protection Association (NFPA).

Consider adding load bank service to your equipment maintenance protocol. Performance testing results are documented and communicated in writing. Contact us at 1-800-CUMMINS or schedule service online.
