Why You Should Perform Generator Load Testing Yearly

Power outages are becoming more frequent due to aging infrastructure and extreme weather. For facilities that rely on standby generators, it’s not enough to assume backup power will work — it must be tested. One of the most effective ways to ensure reliability is through annual load bank testing.

While Foxfab does not provide testing services, we design and manufacture load bank connection cabinets that simplify and secure the testing process. These cabinets are an essential part of a comprehensive power management plan, giving service teams a reliable way to test generators safely and efficiently.

What Is Generator Load Bank Testing?

Generator load bank testing involves connecting a resistive load to the generator and simulating real electrical demand. This ensures the generator can:

• Reach and maintain full kilowatt output
• Operate at proper temperature and pressure
• Deliver stable voltage and frequency under sustained load

Unlike routine weekly starts, load bank testing pushes the generator to its limits — exposing performance issues that might otherwise go unnoticed.

Why Full Load Testing Matters

Generators that operate under light or no load for extended periods are prone to:

• Wet stacking (carbon and unburned fuel buildup)
• Inefficient combustion
• Premature engine wear
• Poor response under real emergency loads

Testing under full load helps prevent these issues and ensures the system can perform during an actual outage.

How Foxfab Supports Load Bank Testing

Foxfab’s Load Bank Connection Cabinets are engineered for fast, code-compliant testing in any environment. Key features include:

• Colour-coded Camlock connections for safe and simple setup
• NEMA-rated enclosures for weather resistance
• Custom configurations to match your generator’s amperage, voltage, and mounting style
• Options in 5052 aluminum, 304 or 316 stainless steel for durability in harsh environments

By installing a dedicated connection point, facilities make it easier for licensed professionals to perform regular testing — reducing setup time and improving safety.

Who Needs Regular Load Testing?

Annual load bank testing is critical in sectors where downtime isn’t an option, including:

• Hospitals and healthcare facilities
• Data centres and telecom hubs
• Emergency response stations
• Utilities and energy infrastructure
• Manufacturing and logistics operations

Ensure Your Generator Performs When It Matters Most

While load testing is typically handled by licensed technicians, the infrastructure that supports safe and repeatable testing is just as important. Foxfab’s Load Bank Connection Cabinets help ensure your testing process is secure, fast, and built to last.
