The "main panel" is normally where ground and neutral are bonded. In
my house (my last three, really), they're actually bonded at a box
under the meter and run to a panel in the basement (attic and front
porch in previous houses). I call the panels "mains" but they're not.
The power being horrendus,
is worth it for view stupendous
We live on a mountain
Youth is our fountain
And backup is our generatorendus
A tree branch takes out our power
When we have wind or even a shower
We go throw the transfer switch
Try not to drive into the ditch
And environmentalists all rally for the flower
The skyline it is all black
I'm thinking of moving myself back
I can't stand this condition
I maintain my position
We've got to buy a Generac.

That was clever and hilarious!
And apropos all the way.
You should sell that to Generac for them to
use as their theme song on the web site & in
Thanks for brightening my day!
My X was a volunteer for Loma Prieta Fire and Rescue, Summit Station.
I know the area (used to) quite well. I donated one of my vehicles
to the fire department for one of their jaws of life demonstrations.
It was pretty cool watching it get chopped up.

Amazingly, it's not easy to break a rear window or side window,
especially if you hit it dead center with a hammer or sledge.

We were told that, if we were stuck inside the car (say, we ran into
a lake or something), that you can't open the doors after the first
few seconds, and, the door won't open until something like 30 seconds
after the car settles into the mud (and maybe not even then).
So, if the door wouldn't open, then try the windows, but, often they
won't open either (due to shorts), so you're only bet is to unhook
the seatbelt and smash out the window.
The way, they said, to smash a window, sans tools anyway, is to
kick at the BIG side (not the small side).
The big side, of course, is the side where the door opens, but
I'm not sure if we kick there just because it's bigger, or,
because it might be weaker on the big side.

I understand what you're saying.
The two things that confuse me are:
a) Why TWO big boxes?
b) WHy so big anyway?
What the heck is in there? A huge switch? Lots of circuits? A big heat sink?
I guess I could open them up and look. :)
To clarify though, the generac does kick in whenever the power dies.
It also runs once a week, to charge the battery.
I don't think it powers the house when it does that though.
So, somehow, the circuitry must be cut off for the battery charging.
Also, almost the entire house, but, not the entire house is energized
when the generac kicks in. Most of the lights and outlets are energized
(which means both interior circuit breaker panels are being fed), as
are most of the outlets.
But the outside of the house also has panels, which run the pool and
well equipment, which I don't think is energized when the power is out.
Come to think of it, the well must be energized? Or we'd run out of
water. So, I'm actually not sure what is energized since most things
seem to work when the generator kicks in.
The pool probably is not, but I imagine your well is. Unless you have a
large storage tank with accompanying pressure tank and pump. It is odd
that there is not a utility fed battery charger, but that "is" an extra
expense both in having a second battery charger and the safety interlocks
to isolate the two. While charging the generator is only running the
battery charger. This is a scheduled event, or there are sensing circuits
for battery voltage.
The transfer switches can be a bit large, and I imagine there are other relays
for interlocks and who knows what else is inside. Pop the covers and take
a look. Turn the main breaker off and see if you can trace the wiring out.
There might even be a schematic inside each cover with information about
the specific function of each transfer switch. A good installer would leave
such information on premise, somewhere.
A powered transfer switch is essentially a large multi-pole relay. There
are many different types and their functions and wiring methods differ
from one model/concept to another. Get the serial numbers off of your units
and look them up. You might even be able to find a manual online. I have
never worked with residential transfer switches, nor Generac stand alone
units. The transfer switches I have worked with are about the size of (or
larger than) the enclosures your switches are in.
Have fun and be careful while poking around.

Normally they run once a week to verify that they are

normally charged via the utility AC. Starting a generator
just to charge a battery wouldn't be very efficient.
The top 2 breakers feed back through a conduit at the top of the service
panel section. This very likely goes to the transfer switches. Two sets
of wires then come back into the service panel. One exits out the top
right. They are the feeders to subpanels that have backup generator power.
The transfer switch boxes each have a contactor (a large relay) that
switches one feeder back and forth between normal power and generator.
Whatever is feed from the 2 top circuit breakers has backup power.
