Fire pump motor listing

Fire pump motor listing

Fire pump motor listing

Can anyone advise on single phase motor listings? We purchased a packaged fire pump system for a 13R town-home, and the reviewer is stating that the motor has to be listed. After getting with the manufacturer, it doesn't appear that the motor is listed, but this package is advertised as fully NFPA 13R compliant, which means it would have to adhere to NFPA 20 as well. of NFPA 20 appears to exclude motors that are single phase from being listed, but I'm not sure I'm reading that line correctly?

RE: Fire pump motor listing

I am going with listed required

What year edition are you looking at???

Make sure you apply all words in that show in the section.

If this is a skid package, and all other components are listed, yes it seems like the motor would be.

Is this in the US?????

RE: Fire pump motor listing

The keywords in NFPA 20 that you're looking for is "unit purchased".

Whoever put together the prefabricated unit had to have purchased the pump, driver and controller as a unit from the fire pump manufacturer which would make the fire pump UL listed at a minimum.

RE: Fire pump motor listing

We are using the 2013e of codes, however I checked the latest 2022e and the verbiage is the same. specifies the motor shall be listed for fire protection use and conform with NEMA standards. states that single phase, along with a few other scenario's, don't have to adhere to where approved.

I searched for "unit purchased" in NFPA 20, with no results as well. The more I'm looking into single phase items and talking with people, it seems that it's pretty common for some of the pump suppliers to use non-listed motors on small fire pumps, using as their backing behind this. Also yes this is in the U.S.

The supplier that sold it to us stated that "The electric motors are not UL Listed. They are a UL Recognized Component. When the pump goes through the Listing process it does so with the motor attached, as a component."

Either way we don't use single phase motors a lot, but just getting more info for future uses is helpful, and it looks like it will be an AHJ decision to allow "approve" or not per

RE: Fire pump motor listing

GlorifiedPlumber1984 is correct, it is no longer required but it once was.

Quote (NFPA 20 2019 Handbook)

Must a fire pump, driver, and all related accessories/components be purchased
from a single source?

NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, does not require
the purchase of all components of a fire pump from a single source. However, consideration
should be given to the listing and compatibility of all system components.

I remember when a unit purchase was required. The unit consisted of the pump, driver and controller.
