Load Bank Testing
CRG Electric provides commercial generator load bank testing in Southeast Michigan to verify that backup power systems can carry electrical demand under real operating conditions. Our team serves facilities in Willis, Jackson, Washtenaw County, Jackson County, and nearby communities with testing that helps reduce wet stacking, document performance, and confirm outage readiness.
Call 734-251-2589 to schedule load bank testing or ask about annual generator testing contracts.
Why Load Bank Testing Matters
A backup generator must do more than start. It must carry the required electrical load when utility power is lost. Load bank testing places the generator under controlled electrical demand so technicians can evaluate engine performance, cooling response, alternator output, voltage stability, and overall system readiness.
Why Weekly Exercise Is Not Enough
Weekly generator exercise confirms that the unit starts, but it does not always prove the system can perform under full demand. No-load or low-load exercise may miss issues with cooling capacity, fuel delivery, voltage regulation, or wet stacking. Load bank testing helps identify these concerns before an outage or critical operating event.
For facilities that rely on standby power, load bank testing should work alongside routine generator maintenance services to help confirm the system is ready before an outage occurs.
Commercial Load Bank Testing in Willis, Jackson & Southeast Michigan
CRG Electric provides load bank testing and reporting for commercial, industrial, municipal, and facility backup power systems. Our technicians use portable load bank equipment to test generator performance under controlled demand and provide documentation to support maintenance planning and readiness review.

Eliminating Wet Stacking & Carbon Buildup
In diesel generators, wet stacking can occur when the generator runs for long periods under low load. Unburned fuel and carbon deposits may collect in the exhaust system, reducing efficiency and increasing the risk of performance issues. Load bank testing places the generator under higher operating demand to help burn off deposits and support proper engine performance.
Comprehensive System Verification
CRG Electric uses portable load bank equipment to test generator output without interrupting normal building power. Testing can help verify engine response, alternator output, voltage regulation, frequency stability, cooling performance, and overall system behavior under varying load levels.
CRG Electric also supports broader commercial electrical services for facilities that need wiring, service upgrades, equipment support, or backup power coordination.
Load Bank Testing Reports
After testing, CRG Electric provides a load bank testing report documenting generator performance under load. These reports can support maintenance records, reliability planning, compliance review, and backup power readiness documentation.
Testing reports may include:
- kW load and amperage readings
- AC voltage & hertz stability
- Oil pressure and coolant temperature
- Voltage regulation accuracy
- Observed performance notes and recommendations
Load Bank Testing FAQs
Is load bank testing required for commercial generators?
Requirements vary by facility type, generator use, insurance needs, and applicable maintenance standards. Even when it is not formally required, annual load bank testing is often recommended for commercial standby generators because it verifies performance under real electrical demand and provides documentation of backup power readiness.
How often should a commercial generator be load bank tested?
Most commercial and industrial standby generators should be load bank tested at least once per year, especially when the generator does not regularly operate under meaningful load. Annual testing helps identify cooling, fuel, voltage, and performance issues before an emergency outage.
Does load bank testing interrupt building power?
No. Our technicians use an external load bank connected directly to the generator. This allows us to simulate full operating demand while your building remains on utility power, helping avoid disruption during the test.
Is load bank testing important for maintenance and compliance?
Yes. Documented load bank testing is often an important part of generator maintenance, reliability planning, and compliance review. It also helps confirm that the system is operating properly under real demand conditions.
What does load bank testing check?
Load bank testing verifies whether a generator can carry electrical demand under controlled conditions. It helps confirm engine performance, alternator output, voltage stability, cooling response, and overall system readiness.
