FAQs

What is a load bank?

  • A load bank is a piece of testing equipment used to simulate an electrical load and test an electric power source like a generator.

How do resistive load banks work?

  • A resistive load bank is the most common kind of load bank. It proves equivalent loading of the generator and prime mover, showing that the horsepower of load applied to the generator is the same horsepower that is applied to the prime mover by the generator. A resistive load bank removes energy from the complete system — load bank from generator, generator from prime mover, prime mover from fuel.  

How do I hook up a load bank to a generator?

  • A load bank is connected manually to a generator via a manual transfer switch.
