I have a Honda eb6500x that I want to use to power certain circuits in
my house during power outages. The generator has two seperate power
producing circuits, Main circuit I is 18.8a and Main circuit II is
22.9. I understand the need for transfer switch to isolate the
generator's power from the power companies lines. I can not see
anyway to wire the generator into the house circuts that does not
require two transfer switches and still allow me to use the full
capacity of the generator? Am I missing something?
Thanks.
Greg.

Yes you are missing something. To connect this generator to a homes
wiring you would use a four conductor cord from the four conductor
receptacle (L14-30P) to the generator terminals of your transfer switch
or interlocked breaker. That delivers 120/240 volt power to your homes
electrical circuits in the same way that the utility does.
120 volts @ 45.8 Amps or 240 Volts @ 22.9 Amps are both 5500 Watts.

It's not unusual to see one winding/output rated at slightly more than the other.
Mostly specsmanship. If you measure between the hots of the two outlets you'll
see
240 volts. That is, the generator is (or should be) connected to produce normal
240/120 volt output just like utility power.
Physically, the generator has two (sometimes more) windings. They can be
connected
phase-alike to provide double each winding's amp rating or they can be connected
phase-opposite to provide 120/240 volt output. Normally when a generator has two
different output ratings, the windings are connected phase-opposite.
You can easily verify this by checking that hot-hot voltage. If it's 240 then
the
generator is wired phase-opposite. If the voltage is zero then it's wired
phase-alike.
If it happens to be phase-alike then you should be able to rewire it
phase-opposite.
Examine the generator's schematic to find the color/label of the two windings.
Reverse the connection of one winding. Pretty much all there is to it. Inspect
the
schematic to make sure the regulator still sees the proper voltage and make sure
the
legs are separate all the way to the outlet.
I recommend installing a 14-L50 twist-lock outlet on the generator if it doesn't
already have one. (If it does then it is surely already wired phase-opposite).
That's
the most reliable connector available for a portable connection.
If you can find an on-line copy of the manual (lots of luck with Honda) or would
care
to scan your schematic then I'll be happy to take a look and confirm all of this.

There are two 240 4 prong connectors on the generator and they make a
big issue about balancing the load. If I connect to the house using
the 30a and I am reading everything correctly then I am only using one
of the two power generating circuits.
Here is a link to the owners manual. It is a pdf that I could not
grab just one page from.

Thank you for taking the time to answer.

Greg -
If I am viewing and interpreting the diagram correctly, then there is
only ONE L14-30 240volt outlet.
If I am wrong, please verify, and correct and reply.
If I am correct, then that single receptacle should supply 240 volts
to your transfer switch.
The second round receptacle "appears" to be a 120 volt - L5-30.
Please confirm and correct my mis-apprehension if in error.
I think that this following text from page 25 is important for you to
consider.
I have highlighted the word TWO with asterisks.
If you only use the 240 volt receptacle then you will be using fewer
than TWO receptacles.
".... When ***two*** or more receptacles are used; prevent overloading
by
dividing the load between the two power circuits.
The chart below shows the rated load in amperes that can be
connected to each receptacle to balance the generator.
The total rated ampere draw is 45.8A. ..."
