Generator Load Bank Test Checklist

Standard load bank testing procedure.

Generator load bank test checklist. 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. 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. 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. Tests shall be carried out on generator set using resistive load bank.

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. 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. Generator load test checklist. 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.

Load bank testing for two continuous hours each year. Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section. Verify all system. A generator load bank test involves an examination and assessment of a genset.

If a generator fails the monthly test it should be operated under a load supplied by a load bank i e. Duration of actual test varies based on type of test nfpa 110 and customer preference. 9 ok ok 1250 49 psi 193 238 jjs 7 seconds to load transfer march 3 2 09 162. At 25 of the nameplate kilowatt rating for 30 minutes.

2 in lieu of nfpa 110 5 13. It verifies that all primary components of the generator set are in proper working condition. The key to a proper load bank test is that it tests your generator at its full kilowatt kw output rating. 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.

In more detail the process occurs in this manner. During this two hour period the unit should be operated as follows. After the test the technician removes the load bank load first and transfers all switches back to the normal position before allowing the generator to cool down according to manufacturer guidelines. The load bank test will allow the engine to run hard and burn off this residue and build up.

At 50 of the nameplate kilowatt rating for 30 minutes. Engine oil level 2.
