Wiring all 110v outlets to inverter?

[Fffrank]

Confused here with the wiring. Currently only my #5 circuit breaker is wired to the inverter. This covers approx 50pct of the outlets in the coach. The other outlets are on circuit #6.

I'd like all of the outlets available on the inverter and assumed I could add a 12awg jumper between the two breakers to enable this.

(To get it out of the way.... We don't use anything besides laptop chargers and computer monitors. No coffee. No microwave on inverter. No blenders. Nothing that could even get close to 15a should we have everything plugged in at once on both circuits.)

While inverting I'm not seeing any voltage at all at the breaker panel. I know that the transfer switch bypasses the main breaker but assumed that the inverted outlets would backfeed back into the panel? Why does that not happen?

Is there any easy way to accomplish what I'm trying to do?

The power flow goes from the ATS to the circuit breaker panel from the C/B panel on the one line to the inverter , then to the inverted outlets .

When power from the C/B is detected in the inverter , the inverting stops and battery charging starts . Determined by and internal control board .

That breaker #5 wire run into the inverter/charger and then out to the outlets .

To do what you want, you need to take the wire out of #6 breaker and run it to the output of the inverter/charger.

That doesn't sound easy at all. I'm not sure there's an easy wire chase that I can access. Would it be possible to run from one of the outlets in the storage bin? I can't remember off the top of my head if those are on the inverter or not......

You will have to figure out the routing of the wire for all the outlets and determine if you can get wire from the inverted circuit to the noninverted circuit This can tie in anywhere but you'll have to remove the wires from the breaker to tie the two circuits together.

Doesn't sound easy to me based on how my coach is wired. All my wires go into the ceiling and then to the different locations.



I had to chase a problem with my bedroom circuit (which was inverted) and it took me a while to figure out the routing. It went from the inverter subpanel, mounted next to the main panel. to the bedroom slideout, then to the outlet behind the TV, then to the outlets in the base cabinets in the bedroom, to the toilet room and then to the basement. Ya, nothing is easy.



While I had eveything apart I decided to add a second smaller inverter so if I wanted I could power my refrigerator off of it.

This may be an option for you depending what you want to do.

There's quite a few items (electric blankets, CPAP, some refrigerators, etc) that won't function with MSW inverter-outlet power, and may even overheat or fail. I found that the hard way after trying to do what you are considering.
Be sure to check.

Our coach(21Accolade) was set up similar, only a few outlets on inverter. All the rest were on a breaker in main breaker panel. Both panels under the bed, about a foot apart. I was able to move the “other” breaker to the inverter sub-panel, there was empty slots. There was enough slack in the Romex to move the breaker without messing with the output wiring. Now all outlets work when inverting, no change in GFCI function that I can see.
The reason I did it is so I can plug an extension cord into basement outlet and run it into car trailer for a battery tender.

It was wired this way for a vary good reason. The inverter is not powerful enough to run everything.

You do not add a jumper of any type. You must remove circuit breaker #6 from the main panel and insert it in the inverted sub panel. The connected wire goes with it.

(To get it out of the way.... We don't use anything besides laptop chargers and computer monitors. No coffee. No microwave on inverter. No blenders. Nothing that could even get close to 15a should we have everything plugged in at once on both circuits.)


Don't worry, a circuit breaker on the inverter will trip if you try to use too much. If it trips too often, the breaker may eventually fail.

While inverting I'm not seeing any voltage at all at the breaker panel. I know that the transfer switch bypasses the main breaker but assumed that the inverted outlets would backfeed back into the panel? Why does that not happen?


Sorry there is no "backfeed" for AC power systems. The main panel is powered by shore power. No shore power mean no voltage. The transfer switch in your inverter/charger/transfer switch makes sure that it works this way. Some people have been killed or injured by backfeeding.

Is there any easy way to accomplish what I'm trying to do?

Remove circuit breaker #6 from the main panel and insert it in the inverted sub panel.

Listen to Persistent - and you’ll be around to tell us how this worked out for you!

On my 2000 dynasty (same year - different model) I have 2 electrical panels - one panel is everything before the inverter- then the power goes through the inverter- then to the 2nd panel.

Is that the way your system is wired?

The inverter that was originally in my rig, would invert on both legs of power.

What inverter do you have in your rig?

If you are for certain talking inverter and not convertor - the inverter powering one or both legs of the coach’s electrical system is somewhat a function of how much battery bank the coach has.

Have replaced MSW with PSW already.

Unfortunately my main C/B panel is in a storage compartment above the bed. The original inverter never had a circuit breaker panel -- it was wired directly to two different circuits.

When I replaced the inverter with a Xantrex 2000w pure sine wave, I added two breakers in a sub panel in the storage compartment with the inverter.

Since these panels are so far apart I'm not sure there's an easy way to combine my circuits as planned.

If I'm reading this right, you can get a 12 ga wire from one panel to the other? If so disconnect the wire from the breaker on circuit 6 in the main and nut it to your new wire to a breaker on the inverter sub panel.
