hooking the 50 amp outlet to the house. I am using the same 3 underground

A 90 amp contactor in the barn won't connect the generator to the house
unless:
1. The electrical service to the house is off, and
2. The service disconnect switch at the house is off.

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
a
1 second electrical pulse to the house to see if it will actuate a coil.
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.

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.

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.

True, but he tried not to do that, that's why he struggled with his transfer
circuit.

that's now way it could go, another is the gernerator could phase-lock

Yes, he can. If the grid is open, and the lineman is trying to repair
that open, there is a (high) risk of voltage.

Again this makes too many hazardous assumptions about conditions and
Jon's ability to do things. Since he's proven he can not design a
simple transfer switch, there is little hope that he will have ideal
conditions for his system to work.

One problem is that Jon engineers for best/ideal conditions, and not
worst case conditions. That is what seperates a real engineer from a
wanna-be like Jon.
