Using Generator As Backup For House Power

[Wilhelmus Schreurs]

I do not know how the figure of a 400 amp transfer switch was determined, but
here you would require at least the size of the mains coming into the house, or
the size of the generator, whichever is greater. (As John said, it must have
both legs AND the neutral, this is so that no unbalance from the two legs is fed
back either)
Also an automatic transfer switch is not required, but a transfer switch whether
it be auto or manual is.
The transfer switch is two fold as well, first and foremost it is to stop
electrocuting the lineman who is trying to repair the circuit, but second to
pick up a long length of line, transformers as well as other loads, you could do
great harm to your generator/engine.

Lest anyone needs to hear it one more time, a manual or automatic
transfer switch WHICH LIFTS BOTH LEGS AND THE NEUTRAL, must be used to comply
with many codes passed since the recent hurricanes.



Generally, backfeeding the house through a "dryer" plug with just the "panel
disconnected, " does not comply, as that method normally does not also
disconnect the panel neutral from the utility neutral.



The penalty for being caught feeding any house circuit (versus feeding just an
extension cord) other than through an "approved transfer switch" in Florida
jurisdictions where the latest code has been adopted, is, the utility company
will "pull" the meter. The re-application takes up to 6 months and is for
INITIAL electrical service, which means; accompanied by plans signed-off by an
engineer/licensed electrician certifying the house/business wiring meets all
current electrical codes.



Learned these goodies from the inspectors in 2005 when I added a house
generator to replace the past "tried and true" Bird methods.

I also stopped complaining about the outrageous cost of a 400 Amp transfer
switch when I got the estimate to bring the 6-year-old house up to current
electrical codes.
