Roland, If I remember correctly there was an analysis based on OSHA required “ARC” Flash analysis of a typical 440 volt fire pump controller. The analysis found that even with the highest level of PPE the person doing the measurements in the controller would need to be at such a distance from the controller that they would be outside the pump room. This is something I heard from a pump controller rep. As a sprinkler contractor I would be very careful measuring voltage and amps in an electric fire pump controller.
I also thought that NFPA 25 is modifying the language in the fire pump controller section of the standard to eliminate the requirement for the sprinkler inspector to measure the voltage and amps. If the fire pump is tested annually the master electrician can be measuring the Amps and Voltage during the test. Just my 2 cents ! Have a fire safe day!

But that’s a lot of up-selling when it comes to selling an inspection. We’re still competing with bottom feeders. And most property managers just don’t care.
