Does anyone know why the code (NFPA 20) requires voltage to not be reduce no more than 125 volts on fire pumps internal controls? Some one asked me that question, but all I really could come up with was maybe there was voltage drop LOL. or maybe 125 v is just a better control voltage?? but those reasons really wouldn't make any difference though.
Does the NEC have any restrictions on that issue? I'm surprised I did not find that in the NEC, unless I'm missing something.
