30 amp cord

[Rondief]

Am I missing something (adapter)? We just purchased a 31’ classic and we went to charge the batteries from the house but my 30 amp cord (and 30 to 110) have 2 flat prongs and a D prong but the airstream has 3 flat prongs. If I am missing something what would it be called and where can I get it.
TIA, Ron

Get something like this to charge at home

Exactly what you need. And you can get it at most any RV supply place....maybe even a Walmart as painful as that was for me to say. Just to get you what you need.
Keep in mind, this is to mainly charge the batteries, run the fridge for a trip load, and maybe run the propane heater if doing a stay at home camp night.. A no go for running the AC.

Thanks but I also need something to hook up to the 30 amp extension cord.

There are a couple different styles of 30A plug, the one you want (that matches the photo of your trailer side socket) is a 30A “locking plug”, sometimes also called a “twist lock” plug. Be sure to ask for that style when getting an adapter, or a power cord. You should have received a cord with a twist lock on one end with your trailer, if you got the trailer used, maybe the prior owner lost the cord, or it was damaged. You might need to go buy one but most of the time there is a power cord with the trailer, I think the factory cords are 30ft long. Lots of options in the RV market if you need to buy one, large hardware store like Menards might even have one for you. Any RV dealer should have one, camping world, bass pro shop, cabellas, etc, they are not unique to Airstream.

The black cord in the photo looks like an extension cord, not the shore cord which would connect to that receptacle. The cord you need to connect to it should have three slots in a circular pattern corresponding to the three prongs in the receptacle. The other end will have three prongs in a pattern to match the extension cord you have.

Something like this is what you're looking for: https://www.amazon.com/ParkPower-Swi...91&sr=8-6&th=1

Available in gray or yellow and in various lengths. Just one of many companies making them, but I've always liked their products.

As previously mentioned, there are several 30 amp plugs, my former boat had the twist lock like you show.
The twist lock 30 amp plug is called the NEMA L5-30P while the RV plug is the NEMA TT-30 P.

Here's a dogbone if you want to extend with your 30 amp cord

although I'd prefer a locking ring.

But wait. Your picture of the 30 amp cord shows a 30 amp EXTENSION not a 30 amp trailer power cord.
Is that what came with the trailer?

Perhaps the mystery is solved by using a real 30 amp RV cord???

Yes, but with everyone’s help I figured it out

Thanks everybody

There are two ways to wire a 30 amp outlet. There is a thread or two in Air Forums on people asking an electrician to add an outlet for their RV, and they end up frying their converter/powercenter.

When an electrician is asked to put in a 30 amp circuit, they are likely to think in terms of an outlet for your dryer (two hot leads and 240 volts). For an RV you need a 120v 30 amp circuit (one hot lead).

Big RV's that need 50 amp circuits are another matter.

Sorry Richard.
In reviewing my post, I see you had (I believe) the correct response in post #6, while I got all excited and finally had the lightbulb go off in post #7.

You got there first, I didn't read closely enough.

No worries. Nice that we both got to the same place.
