Genrator and Auto Transfer Switch
 

I have a functioning 10kw Generac propane generator with an automatic
transfer switch. Circuits from the original panel were of course fed to the
transfer panel. The outside generator feed goes into an external box and
the line then enters the house and goes into the auto transfer switch. All
standard installation I presume.

I have a question: if the generator is removed and the power line from the
generator to the outside box is simply disconnected will all the circuits in
the transfer switch continue to function normally as long as the main panel
has power from the utility company. Simply put if the generator is taken
away will all the circuits in the main [panel and the transfer switch
continue to function or must the circuits that were put in the transfer
switch be reconnected in the main electric panel. I don't believe it is
necessary but...................Thank you..

Should work fine, with the generator removed.

IF you lose power, there will be nothing to transfer and the circuit will
end. It will not hurt to cap it off.

Obviously if power is lost and there is no generator nothing will transfer.
That's not the question.

The low voltage control lines run from the transfer switch indoors to
the generator outdoors. Once the outdoor unit is removed, there is no
relay switching current source to energize the transfer switch, and thus
the switch will never try to transfer.

The low voltage is produced at the generator, runs through the conduit
to the indoor transfer switch (where it is fused on both sides) and is
then applied to the transfer switch solenoid when the generator has
reached stable output after a brief warm-up. Obviously none of this can
or will happen once the outside generator is detached.

Thanks. The low voltage aspect is very informative. I assume it is correct
to conclude that the circuits that were moved into the transfer switch from
the main panel when the system was originally installed will continue to
function normally as long as the breaker feeding the transfer switch remains
ON and as long as utility company power is present ? Thanks

That is what everyone has said and I agree

Yes, but everything was working fine BEFORE power was lost, right?

No generator is the same as generator not running, except for the fact that the lights won't stay lit in your house if there's a general power outage.

why would anyone want to remove a stand by generator?

If it was shot and they didn't want to spend the $$
to replace it would be one reason.

Glad to help John. Many people have helped me here with problems and
issues I have needed help with.

First, to clarify, "the breaker feeding the transfer switch" you refer
to is actually the breaker which provides utility power to the
generator. If it is turned off, the generator will start up, just as if
a utility power outage has occurred.

The "special" circuits which were moved to the transfer switch enclosure
will only get their power switched when the low voltage control signal
to the generator is received, and this only happens when the utility
power to the generator (via the aforementioned breaker) is interrupted.
These circuits are then switched to the generator bus by the transfer
switch. They otherwise are connected to the utility bus, the other set
of contacts / poles on the transfer switch.

Therefore, if the generator were to be entirely removed, the special
circuits will always stay connected to utility power and function as
they did before the installation of the generator.

This is a very nice design (speaking as an electrical engineer and
electronics hardware designer !!) and works just as you would want it to.

Hope this answers your question.

BTW, the generator schematics and all service info is on the Generac
website should you wish to get the full details downloaded in pdf format.

Just sold a property in NOLA with a standby gen set. Owner does not
understand a) standby generator b) New Orleans c) Hurricanes.

Sale contract said to remove, so remove we did. (after a heads up caution to
the new owner).

If you hear back, please let us know what was the general reaction after the
first hurricane. Remove all the crude language, and cussing. On second
thought, there won't be much reply, left.
