You appear to have two control conductors going to the house panel
that are not the AWG 0 cables that you mentioned.  Is that correct?
If it is you can fix this setup  by using a shunt trip main breaker
with a pair of auxiliary contacts.  If you actually interested in
anything other than trying to validate your existing setup let me
know.

Unfortunately, Jonathan L Giffen suffers from mental illness.
He is heavily medicated and probably not receptive to logic or what
you would consider common sense.
Psychosis is a break from reality, like a waking dream state, with its
own logic and rules. While Jon is intelligent, he works by different
perceptions than you or me.

I would not encourage his experiments with mains power. He's dangerous
enough with alarm clocks.

"I took this clock apart and wired it to ring a 95 decimal fire bell
when the alarm goes off. I have to admit I am impressed that the clock
still works even after all my wiring mistakes. Now I have myself a
good clock with a lowd alarm to wake me up."

Would you want someone taking this amount of psychoactive substances
near electricity?

Or someone that needs a "95 decimal fire bell" to wake up even with 30
cups of coffee a day?

Uh, and your point is?

The electrical service goes to the house. There are 3 underground 000
cables that go to the barn from the house. The barn has a 60 amp breaker
in the breaker box at the house. The 12,000 watt generator is in the
barn. It has a 50 amp 240vac outlet, a 30 amp 240vac outlet and several
others. I am hooking the 50 amp outlet to the house. I am using the same
3 underground 000 cables to send generator power to the house during a
power outage.

When the generator is turned on, it tests the service disconnect at the
house to assure the above two conditions are met. This is done by sending

If the coil actuates, the 90 amp contactor latches open and prevents
backfeed into the grid. If the service power turns on during that 1
second, the generator power and service power will clash and throw a 50
amp breaker to the generator.

Actually it'll probably blow his generator, and resolve the problem
almost immediately... With luck, Jon will be fondleing it at the time.

I'd have thought the grid operator would want a cast-iron guarantee that
you won't backfeed the grid, lest you enliven wires that linesmen think
are dead.

What's wrong with a DPDT relay?

He can't back-feed to the grid any way pussy, The grid power is so much
powerful than his funky generator, it will smoke first or nothing will
happen depending on the polarity of the flow.

That's true if the lines he's feeding are actually connected to the grid.
The problem arises when they're disconnected at some other point so that
they can be worked on. If he backfeeds them then, he can electrocute
someone.
