Simple Electrical help, TT 50 amp to Home 15 amp

[FireRob]

Hello again all. Please bear with this total noob question, and thanks in advance for your help.

My TT came with this 15 amp adapter. Am I correct its a 15 amp male and a 30 amp female?




Obviously most of you can tell that my TT is a 50 amp and they gave me that little adapter pictured above...

Would this link below plus the adapter pictured above, be what I need to hook up to an extension cord at home to charge my battery and turn on lights and most importantly will I be able to run the fridge 24 hours before we head out on a trip

Link to 50 amp female and 30 amp male

What else could I do with just 15 amps to my trailer? I know running the AC is out of the question. Like I said above being able to charge the battery and cool the fridge before a trip are my number one hopes for this.

That 15 amp hockey puck adapter is very light. Keep an eye on it or get a better built 15 amp dogbone adapter.

Done deal. Puck is gone. Got an adapter to go to my main TT power cord then into an extension cord to an outlet from the shop that won't have anything else running on that circuit. If I ever try to run the AC I will be sure to do it after a while to give the batterie a chance to charge first.

For quick set up at the house for charging batteries and running refer, the Marinco twist lock to 15 amp is a good way to go. Just the one unit for connection. No hockey puck.
To running an AC unit, I would wait for the converter to recharge the batteries before turning one on.
Verify what else is connected to the circuit from the house.

FireRob,

You may be able to run the AC on 15amp outlet but keep an eye on your extension cord and adapter. With the summer heat we have here you will find both to get pretty hot if you are trying to cool on a 100 degree day.

the 15 amp cord should be #12 wire minimum.

Rodger that, got two good heavy gage extension cords

I picked up some used 30A cords at a low price.

Now that you have an adapter I will add that the 15 amp cord should be #12 wire minimum.
Don't just use some random cord from your bucket of holiday lights.

Hard to see it clearly on smart phone but isn't that a 30 amp Marinco socket mounted on the TT?

It's a 50 amp.

It's a 50 amp and the trailer did come with a cord. I just didn't think of using it when trying to plug in at home and did not include it in the picture.

Now that we all know it IS a 50 amp trailer. LOL

Great info! Thanks everyone!!!

Stoped by a couple stores today and picked up some adapters to plug into the end of my TT cord. One is a 50 amp female to 15 amp male for use at the house.
Also got a 50 amp female to 30 amp male for the RV parks that only have 30 amp service.

Really appreciate the tips about what I can run at home. Microwave is very low if at all on the list. An AC could be high on that list but before now didn't think it would be possible.

Eventually I will be looking into getting a 30 or 50 amp outlet installed. Right now still trying to find the final parking spot for the trailer. As close to my wood shop would be ideal as far as having electrical close by and easiest to add such an outlet but there just isn't a good spot near the shop to park it.

Check the OPs picture again. It's labeled as 50A 125/250V. The ground connection is the one on the outside shell. This is a standard 4 wire 50A twist lock plug.

Learn something every day.
I stand corrected. 50A

FireRob,

What most of us do is to buy the standard flat blade adapters for the other two standard RV plugs and use our rigs OEM cord. In your case you can get a 50 to 30 adapter for about $20 and you already have the 30 to 20 adapter. And you'll need the 50/30 adapter anyway for CGs with 30A only.

You may/may not be able to run your AC. A 12A AC might be OK while a 15A AC is less likely to be OK. Monitoring the voltage and checking the adapters for excessive heat can help determine if it's OK.

Be aware that the standard household plug is usually one of many 15A rated plugs on a 20A CB so there might be other draws and long wiring to consider. Considering you're in hot Fort Worth you might want to consider installing a 50A plug in the house.

I have a 25 ft 50A extension cord plus the rig cord that I use. Sometimes extension cords are far cheaper than installing a closer plug and can be used in other locations.

To answer the O/P's question, yes that is a 30 amp RV to 15 amp outlet connector
and
To answer the question you did not ask: Yes that is a 50 amp Marinco INLET (plug) that matches the outlet on your shore cord

So you need (Already answerd) a 50 amp RV to 30 amp adapter to use that puck adapter.

As to running one A/C on 20 amps.. Done it many times.. In fact on 15 amps odds are good you can run ONE of the following, JUST ONE

Microwave, Air Conditioner, Water heater, Converter if batteries are hungry

(So plug in for an hour or two to let the batteries charge then turn on one other thing)

On 20 amp you can add the fridge to that list.

One Television will likely work as well but multiple and/or computers may put you over.

It is a numbers game, if you know the numbers it works.

Your adapter goes between your power cord and home outlet.
Mine works real well.
Buy the way, your rig looks like 30amp not 50.

Here is a fifty amp to 15 amp adapter to do as you want.

Never seen a 50 socket like that. I would have said it was a 30 amp?
