Proving your generator can carry the building — not just start.
Plenty of generators start beautifully during a monthly exercise and then fail twenty minutes into a real outage. A no-load exercise run tells you almost nothing about whether your machine can do the job it was bought for.
Load bank testing is how you find out for certain.
A load bank is a piece of equipment that creates an artificial electrical load. We connect it to your generator’s output and make the machine work as hard as it would in a real power failure.
We apply the load in stages, usually 25%, 50%, 75% and then full load, and monitor the generator at every step. That means voltage, current and frequency stability, engine temperature, oil pressure, fuel pressure, exhaust condition and cooling system performance.
At the end you get a report showing exactly how your generator behaved under load, and a clear list of anything that needs attention.
Everything else is an educated guess. Load testing is the one procedure that answers the question you actually care about: will this machine carry my building?
Standby diesels that only ever run briefly and lightly loaded never get hot enough to burn their fuel completely. Unburned fuel and carbon build up in the exhaust and cylinders. A proper load test brings the engine up to full operating temperature and burns it off.
Emergency power systems in Ontario buildings are covered by CSA requirements, and load testing is a normal part of meeting them. Insurers and building inspectors ask for the records.
A cooling system that is marginal, a fuel line that cannot keep up, a voltage regulator that drifts — none of these show themselves at no load. All of them show up under a load bank.
No. The load bank supplies its own artificial load, so your building keeps running on utility power throughout.
Most annual tests run a few hours including setup. We will confirm the timing when we quote, so you can plan around it.
Then you have found out on a scheduled Tuesday instead of during an outage. We will tell you what failed and what it takes to fix it.
Yes. Load testing is available as a standalone service.
Lab testing of oil, coolant and fuel shows what is wearing inside the engine.
Clean fuel and a clean tank, so the engine gets what it needs under load.

Tell us the make, the size and the building, and we will come back with a written quote and a date.
