I did this as well before installing a bigger 30amp plug.

It did work OK but the lead did get hot at both ends at the wall and the shore power plug. would suggest setting it up on something so it not just laying on the floor or against the wall and keep an eye on it.

It's common for them to fail and melt.

As noted by others it may be corrosion either on the adapter or the plug. Contact grease or the more readily available (in home centers) grease for aluminum wires might help. Or, it may be that the plug blades are not making sufficiently secure contact with the wires.

In any case there's nothing wrong the with the cord. You just need to replace the plug on the end and perhaps the adapter.

thanks for the help. after looking closer i see that i definitely need to replace the plug, and while the adapter appears fine the heat seems to have fused it pretty tight to the extension cord, so rather than force those apart i will replace them too.

The thing about running an AC is it may run but if it does not have adequate amperage I have been told can be damaged. What is enough amps depends on the model and BTUs.

While commonly heard and repeated I do not believe that voltage drop actually leads to air conditioner failure. I believe that RV dealers and techs like to blame voltage drop for air conditioner failures that are caused by defective materials and workmanship, and so the myth never dies.

I have offered many times to organize an event where we get a used air conditioner from an RV boneyard and try to make it fail by dropping the voltage. I don't think it can be done.

I plug ours into a 20 amp anytime I am working on it in the driveway. I have been known to run the AC and/or heat pump without any problems. That said, if it is really hot, the AC will draw enough to trip the house breaker for the circuit.

Where we store our unit, there are 15 amp outlets, and most of us plug in with an adapter in order to keep the batteries charged.

I'm no electrician but I thought the problem was low amperage not voltage?

What about running TV and DVD player with this power arrangement? Our 30 amp is plugged into a 15 amp outlet and works fine at first...but after a short time TV and DVD player shut off.

OK boys and girls there is a better answer here. Find out the Amperage of the appliances to be used and do not overload the circuit.
Amps Times Volts = Watts...so a 120 Volt 60 Watt Light Bulb = .5 Amps (120 Volts / 60 Watts)
So what does your Refrigerator draw and then what do you have left over for the other loads?
PS I have and use 15 Amp and 50 Amp Adapters as needed...BUT...I try not to overload the Circuits....that is how to do damage to the adapters and trailer.

If you're buying a "dogbone" adapter, I'd recommend one with the contacts 90 degrees to the cord so the weight of the cord doesn't lever the plug out of the socket.
Like this.

However, to my mind, the 15 amp plug is upside down. The ground should be lower than the lugs, no?
Like this!


I don't think there's any household standard, except preference.

We've never had any problem running the television, stereo or coffeemaker off household current.

The AC is a different story.

I was always told running with low amps can damage the air unit . What's everyone else say.?

Me too. On my 2014 FC 23 I plugged into exterior outlets using an adapter at the homes of 4 different friends I visited. This was in Florida in October. AC worked fine. Just had to make sure I turned water heater to propane, I forgot once and the breaker would trip when the AC fired up. With just the AC running--no problems.
