It is not a matter of if the above will work or not, it is a matter of
what is allowed in the National Electrical Code (NEC). And what is
allowed / required by any amendments to that code by your local city,
county, or state laws. (Electrical codes are the law!)
And those codes basically say that there can't be any way that the
connection to the electric company grid and the connection to the
generator can accidentally both be left on at the same time.
Also local electrical inspectors (and your insurance company) want to
see generator transfer switches with a U.L. label. Not some "home made"
And see the proper transfer switch installed (neutral switching or non-
neutral switching). Search google.com for the words...
separately derived system generator
non-separately derived system generator
Because this is advanced electrical work, you are best to have a
licensed electrician determine which type of transfer switch is best and
install it (and get an electrical permit and have the work inspected).
Or use extension cords and plug things into those.
