Converters use between 5 to 10 Amps depending upon what phase they are in.
A 13,500 BTU AC will pull near 15 amps when the compressor is cycling in! If you are lucky the breaker will trip and not damage the AC unit.

And if you plug in a amps hog vaccum cleaner to clean the carpet.

Sounds like you are way over!

A space heater will draw more current with lower voltage?
You better check your meter.




...or how do you like this one.

Right hand on the + side of a 1.5 volt battery and the left hand on the negative side.

I don't feel a whole lot of current, nor are there very many amps flowing.

110 volts on the right and left hand...there's a few more amps and it's not a particularly good situation.

...that being said, when you have more amps flowing through a cable, there is more voltage drop.

Vacuum would be plugged into the house 10ft away, that said I will probably just do the 30amp in the garage and run a short extension cord out to it.

By the original question you are going to be restricted to around 15 amps which is the rating of the plug. Over load the plug and it will get hot and it can cause a fire. The AC and the converter to run the DC circuits IMHO will be over 15 amps.

Reading all of this is why we just had an electrician over today. We get a quote tomorrow. We have a 20 amp in the shop, and DH wanted to plug in to see what would work with it. I wouldn't let him run the AC at all.
We're going to put a 50 amp breaker in the outside box, and run that to a 30 and 20 amp recepticle by the TT.
Anyway, thanks to all for the great information!

I run mine on a 20 amp and run the air. Nothing else though. 15 amp, no air or microwave, but everything else. Have had the plug adaptor get warm when using air and 20 amp though.

15 amps will keep the battery charged and, once charged, it can keep the fridge cold.. On most trailers it can charge and cool at the same time.

YOu should have enough left over for a fan, lights, and Television.

I would not try heating water or running A/C or Microwave on 15, can do (ONE OF TOHSE) on 20 but not on 15. You might get away with it on 15 but .. Know where the breaker is first.


I will NOT be using much of anything other than the AC, converter and some lights while at home. I want it to stay charged, be able to clean it, and this summer have someone be able to use the AC to stay in it for a few nights. They will not use the fridge, water heater, etc. Maybe I will just do a 20amp plug with a good high quality extension cord.
You want a "contractor's cord", the lower the gauge number, the better. Think something like 12 or 10 gauge, with 10 being preferred. And the longer it is, the worse it it. You want to be as close to the outlet as you can get. No 50 or 100 foot cords!!! Those runs are just to long and will lower your voltage by the time the cord gets to the RV.

I am supprised no one has mentioned the adapter you need. This is an adapter
click that will allow you to plug your RV into a 15/20 amp duplex home outlet, and not get hot. If the outlet used is wired for 20 amps, you can run your air conditioner, lights, and TV at the same time. You may use a 30 amp extension on the output side, if an extension is needed. Never plug extension cords on prong side (a very stupid thing to do). Even though you already have a 30 amp outlet at home, you will need this when visiting somewhere with no 30 amp outlet. It is small and very handy.

You will still be limited to the circuit's maximum rating (either 15A or 20A); it will NOT give you additional capacity. This adapter only provides additional contact area on the prongs, hince how it doesn't get as hot under heavy load.

You mean to say if I plug a 30 amp extension cord into a 15 amp home outlet I won't get 30 amps of power??? Boy am I ticked! The extension cord makers are so misleading!!!
