power cord

Is the power supply to TT polarity sensitive ? It is 30A 125V. Standard three prong plug.

DO NOT PLUG IT INTO A STANDARD 30A household receptacle as they are 220 and the tt is 110. You will fry all the 110 appliances and the converter.

Thanks OldCoot. I know it is 110v. My question is can the two flat prongs (1 110v & 1 neutral) be connected either one hot & other one neutral.

Wire it like the diagram shown.

That is what I did. My question again is will it cause any damage if you cross the hot & neutral connections ( not the ground). You really have no way of knowing, unless you check receptacle at every campsite you use with voltmeter, how it may be wired.

Yes it is dangerous. That is why the neutral screw is silver colored and the hot is brass colored. It is long winded to explain why. The easiest way to check the outlet is with a polarity tester. It will instantly tell you if the 30 amp campground outlet is wired correctly. Just plug it into a 15 amp to 30 amp adaptor and plug the combo into the campground outlet.

This may help to answer your question.

If that be the case, you should check every campground receptacle you plug in to, because you really do not know if it is wired correctly, you just assume that it is.

Absolutely every time.

1- turn off the circuit breakers to the 30 amp outlet and the 20 amp GFCI outlet.
2- plug in the polarity combo into the 30 amp outlet and turn on the 30 amp breaker to the outlet. If it checks out OK turn off the breaker, if not DO NOT PLUG IN THE TRAILER. NOTIFY THE CAMPGROUND AND MOVE TO ANOTHER SITE OR HAVE THEM REPAIR THE OUTLET. IF IT IS REPAIRED CHECK IT AGAIN AND ONLY PLUG IN IF IT PASSES THE TEST.
3- now plug the polarity tester into the GFCI outlet and turn on the 20 amp breaker. If the polarity tests OK push in the button on the polarity tester to test the operation of the GFCI outlet, it better trip and shut off. If it does reset it and remove the tester. IF IT FAILS THE TEST DO NOT USE THE OUTLET.
4- now with the 30 amp breaker off plug in the power cord from the trailer and then turn on the breaker.

AS A LICENSED ELECTRICIAN THIS IS THE PROCEDURE I RECOMMEND.

On edit: I strongly recommend a surge protector be used at all times.

Have been RVing for many years & have never myself or seen anyone else check this. That is why I assume that the electrical hook up is not polarity sensitive.
I too am a 45 year electrician & was just looking for an answer to this.
I appreciate all the help.

Another reason many of us won't plug in without our ems. I use a progressive dynamics hard wired unit.
