Correct.  The 240v outlet on my Honda generator has 4  conductors, and  
two of them carry zero current.  How does this  make it safe?



This is not entirely true at all.  Assuming you plug something into  your 
Honda generator that "matches up" to the plug configuration on that  generator, 
you are plugging in a device that requires some sort of 120v  power.  In this 
instance the 3rd wire (white,neutral) will INDEED carry  current.  IF..that 
device did not require 120 volts then the plug  configuration would not fit your 
Honda plug.  The 4th wire of course is a  bond which does not carry current 
unless a fault occurs.   Lou
