[Elecraft] Curiosity Only, somewhat off topic.

Hi David,

I think Milt [he and I share the same family name, no relationship 
however] explained it well.  Regarding safety, I'm not sure it makes a 
whole lot of difference.  However, I distinctly remember reading 
somewhere that 450 VAC is the most lethal.  I don't know why.  That 
service in the USA is essentially all industrial, 3-phase, and depending 
on how the transformer is wired, seems to come in three flavors:  408, 
440, and 480 V.  Virtually all US residential wiring is 120/240 single 
phase.

73,
