The problem is having the controller door open while energized and make break of the contactor and the potential for arc flash injury.
So let's fix the problem and retrofit older controllers with CTs (Current Transformers) and Volt/Amp Meters. We're letting the sanctity of the listing stuff get in the way of safety, both by not taking the readings during testing and exposing workers to injury. Lastly.and sure not least important just having the PPE is not enough, having the training and knowledge of NFPA 70E is just as important. Akin to strapping on a parachute for the first time at 10,000 ft.

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!
