Generator Load Bank Test Report

The only way to determine whether the generator will cope under a full load is to test your generator at its full kilowatt kw output rating.

Generator load bank test report. 6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.

Ideally the load bank should be connected to the load side of the generator breaker. At 25 of the nameplate kilowatt rating for 30 minutes.

At 50 of the nameplate kilowatt rating for 30 minutes. The emergency switchgear should be disabled to avoid accidental transfer to facility load. Any examples are for illustrative purposes only. Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.

It is also important that the load bank is situated in free air space for adequate cooling. A generator load bank test involves an examination and assessment of a genset.

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.
