What is Load Bank Testing for a Generator?

Generator Load Bank Testing is an important aspect of preventative maintenance as it involves examining and assessing various aspects of the generator to ensure the components are in working order. The testing includes producing artificial loads on the generator by bringing the engine to an appropriate operating temperature and pressure level. This process is important specifically for standby and emergency generators that do not run often and may not be exposed to heavy loads on a frequent basis. The load bank test verifies that the generator can handle incrementally higher kW loads for extended periods of time. Madiston PowerTel, Inc. offers 2- and 4-hour load bank resistive tests. The load bank test is a way of verifying that your standby or prime power generator is capable of turning on and operating at its maximum kW output.

*Madiston PowerTel, Inc. recommends an annual load bank test for standby and emergency generators.

*Madiston PowerTel, Inc. recommends following NFPA 110 Emergency Generator Testing Requirements for facilities required by law. This may require a monthly, quarterly, and annual load bank test to be compliant.

**Madiston PowerTel, Inc. offers maintenance contracts for residential and commercial generators (PM1 & PM2).

 Benefits of Load Bank Testing:

  • Comply with NFPA110 Emergency Generator Testing Requirements
  • To make sure the generator will perform as designed
  • Ensures proper working order over time with the aging of equipment, weather, and pests
  • Prevent wet-stacking (degrading performance on the engine) on diesel generators
  • Monitor the exercise period to ensure the generator starts and runs as programmed
