Load Bank Testing
CRG Electric provides load bank testing for backup power systems across Southeast Michigan, including Willis, Jackson, and surrounding Washtenaw and Jackson County communities. Our team simulates real electrical demand to verify generator performance, reduce wet stacking, and confirm system readiness for outages and critical operations.
Why Load Bank Testing Matters
A backup generator must do more than start. It must carry the required electrical load under real operating conditions. Load bank testing helps verify that the engine, cooling system, and alternator can perform when utility power is lost.
Why Weekly Exercise Is Not Enough
Many facility managers assume a generator that exercises weekly is ready for an outage. In reality, no-load exercise does not fully test cooling capacity, fuel delivery, or full-load performance. Load bank testing helps identify these issues and reduce wet stacking before they lead to system failure.

Eliminating Wet Stacking & Carbon Buildup
In diesel generators, wet stacking occurs when unburned fuel accumulates in the exhaust system because the unit runs under low-load conditions. Load bank testing subjects the generator to higher operating demand, helping burn off these deposits and restore proper engine performance.
Comprehensive System Verification
We use specialized portable load bank equipment to test your generator without interrupting your facility’s daily power. This allows us to verify engine integrity, alternator output, voltage regulation, and frequency stability under varying load levels.
Load Bank Testing Reports
At the conclusion of every test, CRG Electric provides a load bank testing report that documents generator performance under load. These reports support maintenance planning, compliance review, and backup power readiness.
Testing reports may include:
- kW Load & Amperage Rating
- AC Voltage & Hertz Stability
- Oil Pressure & Coolant Temperature
- Voltage Regulation Accuracy
Load Bank Testing FAQs
How often should my business perform a generator load bank test?
For most commercial and industrial facilities, a full load bank test should be performed at least once per year. Regular testing helps identify cooling, fuel, and performance issues before they lead to failure during an emergency.
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.
Verify Your Backup Power Under Real Demand
CRG Electric provides in-house load bank testing for commercial backup power systems across Southeast Michigan. From annual testing to pre-season readiness checks, our team helps confirm that your generator can carry the load when it matters most.
