Bingo !!

As Pamela and Mike suggested..

This should be considered a 220 volt plug/connection, correct? The one I have been asking to find..
and should power both Air conditioners...

Thanks

I can't get down on my knees or back to see the plug connection.. I am in line for double hip replacement later this year. so I just held the camera upright, under the plug receptacle and snapped a few pictures... yeah.. its cracked a bit.. but on top of that, cant really tell what it is.. and it almost looks lke it may be bent ?? I'll have my worker here in the next day or so.. so he can get a better look with a flash light.

and I don't know what to say about the 110 to 12 volt transformer... it works.. but I'll need to figure out where it was originally supplied power from or just plan on running a separate power cord to it as is.. as long as it doesn't interfere with the rest..

I'm guessing, perhaps at some point there was a shore power cord connected to that receptacle, and it was "yanked" with enough force to cause damage to the socket. You definitely need it checked out by a qualified electrician before you use it.

I will have to be that Qualified electrician.. I'll replace the socket if it's damaged..

Yah.. I can see some yahoo now, yanking it or prying it back an forth to remove it...

The plug to the converter should be in the same compartmenr, on the ceiling behind the converter

Or even pulling away from a campsite with the shore power cord still connected! You will be amazed at the things you see in some RV parks. I watched a guy pull out with his black tank dump hose dragging on the ground behind his trailer...

I have the same power connector on my coach.
This looks like the right connector: Amazon.com : Conntek CS6364 50-Amp 125/250-volt Generator Power Cord...
The other end that connects to shore power: Amazon.com: Camco 55255 50 AMP PowerGrip Replacement Plug: Automotive
And then you will need an adapter to 30 amp: Amazon.com: Camco 55185 PowerGrip 30M/50F AMP 18" Dogbone Electrical Adapter...
And then an adapter to go from 30 to 15 amp if that is all you have to plug in at home: Amazon.com: Camco 55223 15M/30F AMP PowerGrip Adapter: Automotive

So I guess there was no large, heavy power chord stored anywhere in your coach?
If not, you need to buy or put together a new one. The cable needs to be 6 gauge, 4 wire. Cheaper cable is made with rubber that is more plastic like and will get very stiff in cold climates. The better cable will be softer and easier to roll up. I sure would go through the whole coach an make sure its just not stowed away somewhere. It's unusual for it not to be left in the coach.

Connection to the coach...for a 50a service ? Can't tell from the photo the configuration of the prongs in the RV socket. But this is a guess.

That's the same plug on the 88.. The center post threw me for too.. The 88 connected directly to the outside wall.

If I were going to replace both the socket and purchase/build a 50 amp cord I would give serious consideration to the 'Smart Plug' that Barry and Cindy write about.
Escapees published Barry & Cindy's SmartPlug review

Re: Building you own cord.
In an earlier post to this thread I had offered up the schematics for my 295. They may or may not bear any resemblance to your wiring plant. My point is that they give Foretravel's design capacities for each of the circuits in the coach and which leg of the of the 50 amp shoreline cable they draw from.
Somewhat of an aside, will become clear later
The previous owner (Chief Engineer in Merchant Marine) of my big boat (44' motor cruiser) had balanced the circuit requirements for each leg of the 125/220 system.
He then went down (or up as the case may be) in wire size to construct a much more flexible shorepower cable than the yellow octopus.
We had no problems with it at all during our 6 years on the boat.
Back to topic
Looking at the design loads on my coach I think I could use an 8 gauge rather than the specified 6 gauge 4 wire cable.
Some savings on wire and much more flexible.

Mark,

You've got to start using the right terminology or you are headed for serious grief. RVs, like so many things, have their own jargon and if you just toss in jargon from some other technology you run the risk of people misunderstanding you and leading you - with all good intentions - astray.

First of all, it's NOT considered a 220vac connection. Even though there *is* 220vac on a 50-amp circuit and even though it looks like a dryer or welding receptacle... it's really two 110vac circuits running 50-amps EACH. The correct terminology is "50 Amp RV" circuit.

and,

The 110 to 12volt device is a "converter" or a "converter/charger" (not a "transformer").

Some people/technicians/rv dealers will figure out what you're talking about but I wouldn't count on it.

Don't feel bad Mark. there are a number of us that come from electrical/HVAC/construction backgrounds that had to learn the terminology.......... but now we are ambi-jargonal!

Now if I could just figure out how to explain refrigeration tubing sizes to a plumber.........

Do not get confused between 3 prong 30a RV plug (30 amp 120 volts, 1 hot, 1 neutral, and 1 ground wire) to a 30 amp
3 wire dryer plug. (30 amps 240 volts 2 hots, 1 ground and neutral together in one wire) If you do not know what you are doing you can fry a lot of items in the RV

Boy, that's the truth! Wasn't there a thread here recently about that happening to someone?

Not to nit-pick, but a 3 wire 240plug is just 2 hots and a ground. There is no current carrying neutral. However, the ground can ACT as a neutral--but that is not the design intent. Even though the ground and neutral may go to the same bus bar at some point, the neutral has to go back to the transformer and carries current during normal operation. The ground, is a safety and not meant to carry current during normal operation.

In the old 3 wire dryer plugs the ground was also used as a neutral since part of the working of a dryer are 110 v. The same goes with when 3 wire was allowed to power a cooktop and oven. The neutral and ground were both tied together at the appliance. I think in the 1993 National Electrical Code the change was made where 4 wires had to go to dryer, cooktop, and oven making a separate neutral and ground.

IMHO, I think they make all this electrical crap confusing just so "professional" electricians can charge exorbitant service fees.

No offense taken

On the exorbitant service fees, it depends on who you use. As with anything buyer beware. Some of our competitors charge $350 + per hr., just so happens they are the ones that spend a lot of money advertising on TV and Radio.

Correct. Dryer type 30 amps with no ground do NOT meet code and have not for more than 20 years. And, unless someone is knowledgeable, connecting to one will sure "let the smoke out" of a lot of RV appliances and devices.

Yes, with good knowledge and 4 wire dryer/stove wiring, 50, repeat 50, NOT 30 amp RV service can be wired.

So, curious to know what the companies charge that don't spend a lot of money advertising on TV and the radio...

I you have to go to the expense of buying and installing a new power inlet assembly and complete power cord, then it might cost relatively little more to go with a power reel assembly such as can be seen at Amazon.com: Shoreline Reels CC50D01R-SR 50-Amp Power Cord Reel: Automotive They are available in different styles from various vendors, and I don't know who currently has the best price on them. We plan to upgrade at some point just for the convenience.
