A load-bank test is an essential part of any preventive maintenance practice to ensure your standby generator performs in the event of a power failure. This test checks the generator engine’s ability to perform and provide the required horsepower needed in an emergency. A generator typically runs at a level less than the unit’s rated output capability, so a load bank test provides an artificial load that brings the engine to an acceptable operating temperature, ensuring functionality when your business needs it most.

Over time, lightly loaded generator sets develop wet-stacking and carbon buildup in the combustion chambers and exhaust system, which can lead to increased oil and fuel consumption and poor engine performance. The use of a load bank helps prevent this and determines the generator’s capability to produce maximum output in terms of amperage and horsepower.

At minimum, a load bank test should be performed on an annual basis to improve the life of the engine and alternator. The test gives you peace of mind that your generator will remain reliable throughout power interruptions and keeps your business running. Make sure it’s a component of your customizable Planned Maintenance Agreement.
