Load banks are essential tools for verifying the performance and reliability of standby generators and other power systems. By applying a controlled simulated load, technicians can evaluate fuel system performance, alternator output, voltage stability, and response to real-world electrical demands — before an outage occurs. In industries where uptime matters, such as hospitals, data centres, telecommunications, and utilities, load bank testing helps ensure backup power systems perform when they’re needed most.
While Foxfab does not supply portable load banks, we design and manufacture load bank connection cabinets that enable safe, code-compliant testing in permanent and mission-critical installations.
A load bank mimics the actual load that a power system would experience during operation. This allows technicians to:
Load banks simulate full-capacity demand to validate generator performance. They help uncover issues with fuel systems, alternators, or control panels before a generator is put into service — or relied on in a power outage.
In engine manufacturing and production environments, load banks are used to apply mechanical load through a dynamometer. This verifies that new engines are performing efficiently before deployment.
In live environments, load banks are essential for routine maintenance. They:
Manufacturers often use load banks to demonstrate generator capabilities to customers. This validates system performance and supports written verification in procurement contracts.
Unplanned power failures can disrupt essential services and create safety risks. Load bank testing ensures your standby power system can:
Various Industries rely on these products and can include:
In permanent and mission-critical facilities, load bank testing requires dedicated infrastructure to safely connect temporary load banks to standby generators. These systems are typically supported by:
• Breaker-based Connection Cabinets (Single, Double, Triple breaker configuration)
Foxfab designs CSA- and UL-listed equipment that allows load bank testing to be performed quickly, safely, and without disrupting normal facility operations.
To perform a load test, you need a safe, fast, and permanent connection point between the generator and the temporary load bank. That’s where Foxfab Load Bank Connection Cabinets come in.
Foxfab solutions are:
Our cabinets are built to handle the rigours of industrial and mission-critical testing — whether it’s monthly, quarterly, or annually.
Load bank testing plays a key role in generator reliability — but having the right infrastructure in place is just as important. Foxfab’s connection cabinets make it simple to test safely, on time, and without interrupting operations.
A load bank simulates real electrical loads to verify generator capacity, stability, and performance under operational conditions.
Resistive, reactive, and combined load banks are used to test different aspects of generator efficiency and output.
It ensures generator reliability, prevents costly downtime, and validates performance before real emergencies occur.
