What Is A Load Bank? Load Banks are devices designed to provide electrical loads for testing power sources such as for testing power sources such as Generators and Uninterruptible Power Supplies (UPS). (Dummy Load) Normal/Emergency Load s Load Bank

Why Are Load Banks Necessary? Maintain reliability of the Emergency Power System by testing of the engine generator (s) under load. by testing of the engine generator (s) under load.

Testing With A Load Bank Will Help Insure   

   That When You Have A Power Failure   

   Your Engine Generator Will Deliver The Power It Is Required To Do!

Recommended / Required Testing Of Engine Generators Frequency Duration Capacity Monthly 30 – 40 Minutes 50% to 60% of Engine Generator Rating  Annually 2 Hours 2 Hours 100% of Engine Generator Rating  (Resistance/Reactance) (Resistance/Reactance)

When it is unfeasible to apply actual load, it is recommended to use a Load Bank

 Diesel…The Preferred Fuel For Standby  A Diesel Engine Generator Should Always Have At Least A 50 – 60% Load Connected While Running Or “Wet Stacking” Could Occur Another important reason to operate your standby generator under load…

“Wet Stacking”  Unburned Fuel Causes Carbon Build Up  Excessive Oil Consumption  Reduced Horsepower….Reduced Efficiency  Premature Failure

Wet Stacking Is Most Common... Applications With Varying Loads Engine Generators Sized For Pump Starting Currents All Pumps Running At One Time And
