The recommended procedure to follow for the load bank test would be to.
Generator load bank test requirements.
In addition to routine maintenance you ll also need to conduct ongoing operational tests of your epss.
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.
Load bank testing for two continuous hours each year.
Ongoing requirements according to nfpa 110 chapter 8.
A generator load bank test involves an examination and assessment of a genset.
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.
For example if a generator is used as a backup for services associated with loss of life or serious injury such as in a hospital setting the testing requirements are much more frequent.
Step load the generator with the load bank until the desired load is reached.
During this two hour period the unit should be operated as follows.
Any examples are for illustrative purposes only.
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.
8 2 4 3 if a generator fails the monthly test it should be operated under a load supplied by a load bank i e.
Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.
The frequency schedule for load bank testing on a generator often depends on how the generator is classified and what it is a standby for.

Transfer all manual or automatic transfer switches to the emergency source.
6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.
The purpose of these tests are to periodically verify the function of the system against the standard.
It verifies that all primary components of the generator set are in proper working condition.
