Why Load Bank Testing Matters

Load bank testing is the only way to verify that your commercial generator can deliver its full rated capacity under real-world conditions. Without regular testing, generators that run only during weekly exercise cycles operate at minimal load—leading to wet stacking, carbon buildup, and potential failure during the critical moments when you need them most.

NFPA 110 requires annual load bank testing for Level 1 and Level 2 emergency power supply systems, including hospitals, data centers, government facilities, and any building where life safety systems depend on backup power. Buffalo Power Solutions provides documented load bank testing with compliance reporting that satisfies inspection and audit requirements.

What Load Bank Testing Verifies

Full Capacity Verification

Confirms your generator can sustain its rated output under continuous load—not just idle or light-load conditions.

Wet Stacking Prevention

Burns off carbon deposits and unburned fuel that accumulate from light-load operation, extending engine life.

Compliance Documentation

Provides documented test results for NFPA 110, Joint Commission, CMS, and local authority inspections.

Performance Baseline

Establishes baseline performance data to track degradation over time and plan maintenance proactively.

Our Testing Process

{ "title": "Pre-Test Inspection", "description": "Visual inspection of the generator, coolant levels, oil levels, battery condition, and all connections before applying load." }

{ "title": "Incremental Load Application", "description": "Load is applied in 25% increments, monitoring voltage, frequency, oil pressure, coolant temperature, and exhaust at each stage." }

{ "title": "Full-Load Sustained Test", "description": "Generator runs at full rated load for the duration required by NFPA 110 or facility requirements, typically 2-4 hours." }

{ "title": "Documentation & Reporting", "description": "Detailed test report with all measured parameters, pass/fail status, and recommendations for any corrective actions." }
