Even the NEC (US National Electrical Code) is inconsistent. There are
references to 120/240, 125/250, etc. Even 125v, 115v. Don't recall seeing 110v
lately but it is a thick book and some sections rarely change.
Let me answer this one by saying that the designers at Elecraft indeed are
amateur radio operators, but they are some of the best and most professional
engineers I have had the pleasure of working with. The same goes for the other
folks who keep things running.
The proof here is in the pudding.
I believe that is correct. A lot of folks thing that electrons move all
over an antenna... They move about an inch...

I believe you will find that Elecraft designs are conservative.
To use a 15 volt rated capacitor on a 15 volt rail would be foolish.
You will find those capacitors rated at 25 or 50 volts.

That is true for Elecraft equipment but I was referring to "generic" 12V
stuff. For example, some "12 V" things that I use are external disk

I can answer that one. It is in the equipment manuals. 15V max.
Some components are rated at that level.
You really don’t want to go too high or you lose a lot of power dissipated in
linear voltage regulators inside the equipment.
Of course too low and the transmitters can have issues. Things lik
