Generator load bank testing requirements.
This standard contains requirements covering the performance of emergency and standby power systems providing an alternate source of electrical power to loads in buildings and facilities in the event that the primary power source fails.
Can the generator load bank test be combined to meet the 36 month test as well as the 4 hour load test.
During this two hour period the unit should be operated as follows.
Load bank testing shall be performed for a period of four 4 hours at the full rated load of the generator and witnessed by a county representative.
The equipment used to conduct a load bank test produces artificial loads on the generator by bringing the engine to an appropriate operating.
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.

Emergency power generation systems fall under a number of regulatory oversight conditions and code requirements.
It verifies that all primary components of the generator set are in proper working condition under loaded conditions.
A load bank can be connected to the generator to get above the 30 requirement.
The purpose of these tests are to periodically verify the function of the system against the standard.
Load bank testing for two continuous hours each year.
