Understanding Load Bank Testing
Load bank testing is a preventative maintenance practice used to ensure a backup generator can perform under varying electrical loads.
Generators, especially diesel engines, should not be run consistently at light loads. Running at less than 30% load can lead to "wet stacking", where unburned fuel accumulates in the exhaust system.
- 25% to 50% Load: Warm up and initial performance validation.
- 75% Load: Standard operational load testing.
- 100% Load: Validating the generator can meet its fully rated capacity without overheating.
