Load banks are an important asset for any industry to have because they ensure the proper running of equipment in the event of power outages. Specifically, a Load Bank Hire can create a load similar to daily use and test a power source for running efficiency. By imitating the original load, there is no chance of random or unpredictable current. Load banks are a contained system unit that integrates both controls and accessories into one installed location. The power source will supply the power, but the load bank uses this energy to protect and support the power source as well as test it.

Where do you use a load bank?

There many applications for the load bank, including battery systems, inverters auxiliary and ground power units, engine generators as well as hydro, aircraft and wind generators. Load banks have several purposes across a number of industries.

Manufacturing testing

Engine cell testing: load banks are used to test new engines at varying mechanical loads to ensure that the engines can function efficiently in any circumstances. Dynamometers are used to connect the engine to the load bank and once connected it monitors performance making any adjustments as needed.

Generator cell test: manufacturers of standby generators also test their units with load banks. By using certain loads the endurance and stability of the unit can be measured. If there are any errors, the load bank can calibrate the generator allowing it to meet the desired tolerance and required specifications.

Field testing and exercise

Once generators are installed, it is a good idea to get them tested regularly to make sure they maintain top level performance. Load banks are used to verify generators because they imitate the load of the facility and if there are any problems, they can be identified before the generator is actually needed in an emergency situation.

Wet-stacking elimination

With regards to diesel generators, load banks are also used to ensure the units can properly consume fuel. When fuel consumption is not optimal, wet-stacking occurs which is the buildup of oils and grease which interferes with generator function and hinders efficiency.


When potential customers want to see the function of a generator, load banks will be used to run them for demonstration purposes. This allows for the identification of a specified performance level, which can then be outlined in any contract for purchase. This way the buyer has written proof of testing and expected performance levels.

Power outages are more common than people think, and they can be a major inconvenience to factories, businesses or any professional or household setting. Using a load bank to test your generator during the year will make sure it can perform at the desired level and keep business going during an outage. Additionally, their use for demonstrations and correcting systems such as turbines and batteries as well as providing optimal loads for primary power sources makes them handy to have around.

Load banks also help to protect internal components of the generator and provide information for any needed repairs. Keeping your standby generator in good condition is a necessity because emergencies can occur at any time.
