The contractor on our project wants to complete the fire pump acceptance testing soon but the generator is not on site yet. NFPA 20 (2013 ed) states in 14.2.8 that “On installations with an alternate source of power and an automatic transfer switch, loss of primary source shall be simulated and transfer shall occur while the pump is operating at peak load.” Would it be acceptable to connect a temporary generator to complete the acceptance testing and then install the “permanent” generator at a later date without needing to redo any tests?
The standard doesn’t address this specifically that I can find, but in my mind the test is performed to ensure the transfer switch will operate correctly and the testing of the actual generator is a separate task, so it wouldn’t be crucial to have the permanent generator in place. It would make sense that the temporary generator would need to be sized the same as the permanent generator but wondering if anyone can tell me if this is acceptable? Other food for thought…wouldn’t the above scenario be the same as if the generator fails 6 months from now and gets replaced?...would the fire pump starts and flow testing be required to be performed again?
