Changing what the ATS powers 2020 Intent 28Y

[tom1957-WO]

I have a 2020 Intent 28Y. Currently the ATS powers my refrigerator and 2 TVs. I would like to disconnect the bedroom TV and instead power the 2 outlets in the nightstands.

Does anyone have any experience with this?

Your ATS is an automatic transfer switch (ATS). It powers everything it just "switches" between your generator and shore power.

What are you speaking of rather than ATS? I'm guessing it's your inverter that you mean.

The inverter is powering your TVs and your fridge. But it's extremely likely it's also powering one plug in the kitchen, one plug in the bathroom and one or ever two plugs in the bedroom.

So, get back to us about what you mean and perhaps we can help you out.

I think this may be one which has no ATO but has an option for a switch at the inverter??
But it may be a trick to get those outlets moved /switched as the inverter seems to be on the passenger side and forward from the bedroom on both builds.

To get the accurate info on wiring we may need to know which build you have.
If the serial number is not on handy paperwork, etc. it may be easier to check a label near the driver's left side for SERIAL number. The 7th digit is all that is needed! 2 or 3? VIN is often next to the serial but not what we need!


Details, details, it's the picky little details!

Thank you for the quick response. I hope this is better stated than my last question.

I am referring to the inverter. My serial number is the 1st one down in the list 10V1202.

My equipment is located in the cubby under the kitchen slide. There is another, black box that plugs into the inverter, I assumed this was a transfer switch as all AC power output is directed through this box. There would also need to be something to detect power on the circuits and not let the inverter send power to already powered circuits.

Just forward of that cubby is one that contains the batteries and myriad breakers, but they all seem to be 12v. The wiring diagram I downloaded is not showing the layout of the wiring from this black box to anything else.

On "home" systems I've looked at this device accepts power from the inverter and then distributes it to selected breakers inside the homes breaker panel. I am wondering if this is the same for the RV's system.

Unfortunately, after the 2013 model year, Winnebago stopped sharing full wiring diagrams with owners. That said, look for a drawing the do still share for your model called : Wiring Instl - 120 V Body. This one generally will show the original configuration so far as what outlets and appliances are from what breakers, and where the inverter and inverter transfer switch (if separate) is. It is probable that the inverter/transfer switch is in-line with part of one 15 A branch circuit, this is the standard way WBGO did it on the lower priced model lines.

So long as you only want to draw minimal AC loads (couple 100s of watts max) from the 2 outlets you want to feed from the inverter, it should be very do-able. At least in my Vista the outlets are fed from two 15 amp breakers and originally only part of one of the 15 amp branch circuits was fed by the inverter.

A common feature of today’s inverters is built in AC pass through. When not plugged in the inverter is capable of taking 12vdc and inverting it to 110vac, but when on shore power or generator it simply lets that power pass through to whatever circuits are on the inverter’s output.

On Intents, Winnebago lowered their manufacturing cost by using an inverter that does not have AC pass thru (built in transfer switch). They use a separate 15 A transfer switch located near the inverter. It works the same as the way Winnebago had done it in the past with the Xantrex 1000 with integrated pass thru, but at half the manufacturing cost.

Ok, sounds like a small difference in names! No big thing!
ATS is transfer for ALL 110AC from shore power to generator. What I think you have is not ATS but near the same except only for the portion that runs through the inverter. Inverter transfer may be a name that comes close?
But it only controls/switches the 110AC that comes from the cord or generator to the inverter or the items which can be switched to the power "made" by the inverter!
I'm limited as I can't see the slide when looking at the electrical and no experience with that RV, so some guessing involved!
Does this look like the spot where you find a switch?
Click this snip to see better!

Would this seem to match what you find powered by the inverter and switched as currently set?


It shows a fair amount of the 110 Ac does come through the inverter but not ALL as only this one breaker!
check to see I'm still on the right track before trusting and getting into how to change things!

I like to know where I am before heading to where I want to be!

If correct so far, I think I see the question as this?

 

[powercat_ras]

First of all this whole thread is talking about the less costly lines of WBGOs that DO NOT have the Integrated Converter Charger - Inverter AKA what is commonly known as a "Magnum". This whole thread is also talking about WBGOs that have small inverters that are 2,000 watts or less.

> ATS is transfer switch for ALL ...

True, BUT this is NOT ATS for inverter for the RV types discussed in this thread. This ATS connects the on-board generator to the power box main (ALL) in place of the shore power connection.

The OEM ATS for inverter on the RV types in this thread is a smaller less expensive unit that can only handle 15 amps thru it's contractors, not the 30 or 50 that ATS for All must be able to handle.

Accentually, yes, but I was hoping to add bedroom outlets to the existing inverter circuit. I have to look at the CSW-TS15 15A Transfer Switch on my system and see if there are multiple "load" options (e.g. can I power more than one circuit in the main box). I don't know if it is a safe idea to split the inverter wire between two circuits - I don't think I want to go there. I'm thinking of just extending the original circuit to include a "new" outlet where I need it. I'm trying run a 35w cooler/freezer.

The schematic helped a great deal - thanks!

It will take some looking/thinking to find how to connect things to get where you want. One way is to move one or more of those outlets from the circuit/ breaker it is on over to the output of the inverter.
That may take some thought on how much current you can get out of the inverter, then look at what items are likely to be used at the same time and not overload the inverter!
A freezer, run more full time, is different than I was thinking on maybe something like a CPAP which would only run at night when less likely to be using the TV!
It would be fine to leave several connected, just as long as ALL items were not used at the same time to point of overload!
Are you aware of the way Winnebago marks the romex and smaller wires with ID to help sort them?

Nightstands outlets are on BRN and you may want to put it partway out on YEL circuit?
Maybe you can find that at some connection point mid way?

Another good info site is the interactive parts drawings here:
https://catalog.winnebagoind.com/menu/Parts.htm
it is a trick to learn to drive but it can let us look through walls like superman and that can save crawling, so I love it!
I did some looking at where the outlets you might want to move over from feeding off the load center to feed off the inverter!
Bit of trouble as they are on different sides of the RV! But maybe some ideas if you can see where they put things. The installation drawings are really fuzzy and not too much help but give general ideas maybe.
On the drawing above, I saw a connection in the line to the nightstand that says located behind load center. I do see it on the parts drawings but that doesn't tell me what it takes to access it or if even possible! Approach with an open mind???


Any way to cut TV feed, replace with connection to load center and at same time swap in the line to the nightstand outlets?
Would that get what you want?

Sorry, I can have ideas but you have to look at what you really have! Maybe it is nuts!
Throw away what doesn't fit!!

The Intent models are wired to only power the three tvs and the one main residential refrigerator—not even the outdoor kitchen one.

A few of us that own the Intent model have done what you wish to do.
I rewired mine so that ALL plugs will now run off of the inverter, rather than when only on shoreline or generator only.

Of course, in my case, I had to install a 2,000 watt inverter, but if you’re sacrificing one plug for another, of two, you’ll be ok with the OEM Magnum one.

I might suggest, if you are a Facebook user, you join the Intent group.

But there’s also a lot of information on this side, if you look for a super long thread called, “FOR ALL INTENTS AND PURPOSES”, where several of us traded ideas on how we did it.

What Moric said is essentially spot on. You just need to look at the electrical diagram in reroute the TV to the bed stand.
