[StBernard] Press Conference & generators

[Westley Annis]

re:  Chief Stone's statement.

One of the advantages these whole-house or "most of the house" generators
tout is that they automatically kick on when they detect the loss of power
off the main lines.  If they do that, don't they disconnect from the mail
line?  If they are only designed to power certain circuits in your house,
i.e. to power your fridge(s)/freezer, a/c-either central or a window unit
and some lights, then how does it backfeed to the main utility lines?  With
the lack of power for an unknown time I'm sure some people already have or
were looking to purchase these types of units.  It seems that Chief Stone is
trying to "throw water" on the idea, so-to-speak.  

If these units don't automatically disconnect from the main lines, is there
a way a homeowner could do this themselves to avoid this issue of backfeeds?
