Generator Load Bank Test Checklist

The generator is then step loaded with the load bank until the desired load level is reached.

Generator load bank test checklist.

A load bank test ensures that your generator will run property when it s needed so that you can fully depend on it during an emergency situation. The key to a proper load bank test is that it tests your generator at its full kilowatt kw output rating. It verifies that all primary components of the generator set are in proper working condition. 2 in lieu of nfpa 110 5 13 2 3 h i hook up the dry type load bank to generator and perform a stepped load test on the generator at 25 50 80 and 100 of the nameplate kw rating of the generator.

Standard load bank testing procedure. And every 36 months you ll need to run level 1 epss systems for the amount of time specified in your application s class up to four hours of runtime 8 4 9 1 2. The equipment used to conduct a load bank test produces artificial loads on the generator by bringing the engine to an appropriate operating temperature and pressure level. A generator load bank test involves an examination and assessment of a genset.

Load bank testing for two continuous hours each year. During this two hour period the unit should be operated as follows. Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section. 6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.

O engine exhaust temperature during test if applicable p kw load under test q identification of unsatisfactory conditions and corrective action taken including parts replaced note. In more detail the process occurs in this manner. Duration of actual test varies based on type of test nfpa 110 and customer preference. The following is the basic step by step procedure for performing load bank testing on a generator set by utilizing a portable resistive load bank unit.

At 50 of the nameplate kilowatt rating for 30 minutes. Generally speaking you ll need to perform a weekly inspection and a monthly load test on your epss 8 4 1. If a generator fails the monthly test it should be operated under a load supplied by a load bank i e. At 25 of the nameplate kilowatt rating for 30 minutes.

For gasoline powered natural gas powered or propane powered generators that do not meet the testing requirements outlined in 1 a above it will likely be necessary to add more load to the generator or conduct a load bank test to comply with testing requirements a load bank is typically a mobile piece of equipment that simulates the actual.
