Need Help Wiring Inverter.

You need a subpanel to break out the inverter items.

I don't understand, I don't want it to backfeed the main panel, that's the whole idea of not feeding the main panel with the ats. I just want to run one dual breaker off the ats output. Do I really need a whole subpanel for one breaker?

a box with one or two circuit breakers
can be a sub panel or a switch box, depending on how its wired
coming from the ats to a dedicated circuit Not powered by anything else
it is both a switch box and protected circuit at the same time

a sub-panel in RV context with a generator, shore, and inverter
is s selection of one or more circuts that can be powered by shore/gnerater switched by main ats,
and also powered by just the inverter
in other words that panel has multiple possible power sources
it isolates circuits that will be powered by inverter when other circuits do not have power

for safety things have to wired where there is absolutely no possibly of two power sources being connected to the same circuit
a sub-panel with mechanical interlock allowing only ONE choice, either/or is the safetest way of doing this

an ats choosing between two sources ( the oem breaker panel and the inverter ) can be used, as long as there is a CB between the output and the circuit

i have an ats on my fridge circuit, so it switches to a circuit from the breaker panel when the generator comes on

wiring can get confusing
and sometimes, its not clear what somebody is trying to describe

Indeed it can get confusing. I think you are not understanding my diagram, so it's probably my bad.

I want to isolate the 15/15 dual breaker. So although it is drawn on the main panel (it's current location) I want to isolate this breaker such that it's power source is only the output from the ATS. Thus it can only be powered by one source at a time. It would be nice if I could leave it mounted in it's current location (but separated from the main panel) for accessibility purposes.

If I have to add a sub-panel I won't have easy access to it and it will require tools to get at. That's why I really just want to wire up a 15amp/15amp single breaker without the need for an entire sub panel (or are you saying it would be considered a sub panel anyways?).

The only breaker I need to power using my inverter (and ATS) is for the outlets, and all outlets are on the existing 15/15 breaker.

If your saying what I want is not possible, I'll just run one of the 15 amp breaker outputs circuits to the ATS, Inverter to ATS, and inverter output to what used to be connected to the 15A breaker. But then only 1/2 my outlets will get inverter power.

I would prefer to run output from the main breaker into the ATS, inverter into ATS, and have the output going into a single 15/15 breaker's input though. This would give all my outlets in the trailer inverter power or shore power, and I would not have to remember to flip breakers when starting the generator to charge the battery etc since only the outlets would be wired to the ATS.

So in the end I the question is: Can I power a breaker without a panel or sub panel? Do they make a single 15/15 amp breaker that take in a wired input instead of needing to be attached to a panel?

If the generator is running and someone turns on the inverter they will both feed the same bus and the smoke comes out of one or both.

Yes you could switch some breakers manually but then why bother with the ATS.

If you just need one branch circuit then it could come right off the ATS.
Might get by with two circuits off the ATS depending on loads.

Have you mapped all five circuits?

As for wire I would just use the max that the terminals are rated. I recommend battery cable over speaker wire.

I get my provisions here: http://www.genuinedealz.com/marine-wire/marine-battery-cable

Best value is to have them put the correct battery lug on one end and sealed with heat shrink.

Please read the above. There would only be one power source to the 15/15 breaker at a time. I want a 15/15 breaker (Like I have now) to be powered by ATS output, instead of by the main panel.

I'm not using speaker wire I'm using amplifier wire. Here is a direct link

Yes I have mapped all 5 circuits :)
