Bill, the term "single point ground" is a terrible misnomer.  It does 
not mean a single point ground, or only one ground point.  When you 
think about it, there is no such thing.  Only the first person to tie 
something to ground would be able to have it and everyone else would be 
out of luck.

I refuse to use the term because of the confusion it causes.  Most 
people think the term is self explanatory, but it is not.  I substitute 
the phrase "common ground tie point" instead.  It is the single point 
where all your ground systems tie together.  There are usually many 
ground connections within this system.  How you hook all these together 
is important to control where the current goes, and that is what the 
common ground tie point is for.
