AC logic please for bypass of inverter

Hi
We just wired our 30 amp shore power into the boat to a 30 amp double pole breaker.



We then wired it to our charger inverter.
All works well.

Now we want to eliminate one 110 volt outlet and the water heater form the charger inverter. We do not want the inverter to supply AC to the Water Heater or the 110 AC outlet.

So I guess it is can we just use one bus for the power (Black) wire insteda of two buses one for the Whte and one for the Balk wires?

We have little room left for more buses.

The wiring.

10\3 - Black, White and Green

The AC comes into the boat Black, White and Green.

Black, White and Green wires connect to the top of the 30 amp breaker.

Then a new set of Black White and Green wires connect to the 30 amp breaker.

The green wire connecting to the Green on top of the breaker for the reverse polarity check.

Then at the bottom of the 30 amp breaker the Black and White wires connect and run to the charger\inverter.

From the charger\inverter the Black, White and Green wires run to different buses.
At the buses all the other AC wires are connected.

The port and starboard AC outlets ect.
It all works fine.

Now we want to eliminate the Water Heater and one outlet from the charger\inverter.

We have limited space for more buses, re-staed .

We are thinking that one bus would work? We could attach a Black power wire from the bottom of the 30 amp breaker where it also goes to the charger\inverter only this one goes to a different bus and not the charger inverter.

At this bus we wire the a Black power wire from the Water Heater and the Black power wire from the 110 outlet and not to the bus where the other black power wires go.

Questions:

Now they are separate from the Charger\inverter and will not be live if the inverter is on?

Will this work and will the inverter think they are attached and be working to supply power to these two items at the separate bus?

The inverter will still see the Green ground and the White natural wire for these two devices.
