What Do Class, Type, and Level Mean in NFPA Emergency Power Systems?

NFPA defines Class by runtime duration, Type by power restoration time, and Level by risk, where Level 1 systems safeguard life and safety, and Level 2 systems protect property or vital operations.

What Are the Most Common Causes of Generator Failure?

Generators often fail due to weak or dead batteries, contaminated fuel, coolant or lubrication issues, transfer switch malfunctions, blocked airflow, or neglected preventive maintenance routines.

Why Emergency Fleets Trust Our Generator Testing

FAQs

What Are the Signs a Commercial Generator Needs Testing?

Common warning signs include hard starting, unstable voltage, frequent shutdowns, unusual noise, warning lights, or failure during load changes. Generator testing can check output, battery condition, fuel delivery, controls, and electrical connections to identify problems before the unit fails during an outage or emergency.

Why Does My Generator Run but Fail Under Load?

A generator that runs normally at idle but struggles under load may have fuel delivery problems, weak electrical output, overheating, control faults, or internal engine issues. Load bank testing helps confirm how the generator performs under realistic demand and can expose failures that may not appear during a basic no-load inspection.

How Often Should a Backup Generator Be Load Bank Tested?

Backup generator load bank testing is commonly scheduled as part of a preventive maintenance program, with frequency based on usage, operating conditions, and manufacturer guidance. Testing under controlled load can reveal weak batteries, cooling issues, fuel problems, and voltage instability before emergency power is actually needed.
