Facilities that rely on backup generators can't afford uncertainty when the power goes out. Whether you're managing a hospital, data centre, or industrial operation, your generator needs to perform under real load — not just during idle tests. That's where generator load bank testing comes in.
Load bank testing is a preventative maintenance process that simulates a real electrical load on a generator. This test evaluates whether the system can:
Unlike simply running the generator at no load, this method applies meaningful stress, helping identify issues before a real emergency occurs.
Generators that sit unused — or only run under light load — can develop performance problems such as:
By applying a simulated load, facilities can burn off harmful deposits, validate engine response, and confirm that all components — including the alternator and control systems — are working as expected.
A standard test follows these steps:
After testing, technicians typically review the results and recommend maintenance if required.
While Foxfab does not perform load bank testing services, we manufacture Load Bank Connection Cabinets that make testing:
Available in wall-mount or pad-mount formats, Foxfab cabinets streamline the process for electricians and testing professionals, supporting testing up to 1200A and beyond.
Qualified technicians should always conduct testing, ideally once yearly, as part of a preventative maintenance program. Foxfab's cabinets enable that testing by providing a safe and permanent access point for connecting temporary load banks.
For mission-critical industries, annual generator load bank testing is non-negotiable. Foxfab Load Bank Cabinets provide the infrastructure needed to keep your generator ready—and your people protected—when outages strike.
