Hi Gary,

Thank you for stating this so clearly. This is an important safety issue.

And if there are any lower voltage loads inside a piece of equipment 
using a three wire 240 VAC power cord, those lower voltage loads derive 
their supply voltage one way or another from the full 240 volt supply. 
Only in a four wire system, when there is a neutral wire, and a ground 
wire, can a 120 volt load connect from one hot lead to neutral.
