Question about portable AC units and amperage

That would be fine. 50a is 50a per leg.

Thanks. Also wondering if anyone has experience cooling 30' travel trailer with one of the newer dual hose portable ac units.

I bought my Mom a single hose 12K BTU unit for her 50 y/o house with no insulation. I was amazed how well it worked!
I would give it a try.

I just purchased a high end portable ac unit for my winter home in Florida.

I took it back the next day.

That exhaust hose gets HOT and emits a ton of heat into the room. And the intake on the one I bought was in the back right next to the hose. So all it was doing was sucking in the heat from the hose.:R

After plugging it in, the humidity in the room doubled and the ac unit spent the next 10 hours trying to cool the heat from the exhaust hose not the room.

Went on line and there were tons of complaints about the heat from the hose, and there were tests showing the heat coming off the hose to be 100 degrees plus. Then their were a hundred different websites where people were making and/or selling ridiculous tacky looking insulation fixes for the hose.

AND you have to move it to drain the water off every so many hours depending on how high the humidity is where you live. If you forget to drain it it shuts off. Mine had no drain hose just an opening so you had to take it to the front door and hope for the best draining.

Just saying this is what I experienced just this week with a portable. I'd REALLY look into all what a portable does and does not do before you leap into buying one. I didn't and just bought one, what a mistake.

Especially the draining of the water. The reservoir size was very very small. If you left your RV for any length of time if the water tank filled up the ac will shut down. You'd be coming back to one hot RV.

And I am guessing that in a small RV that heat from the hose is going to just add a considerable amount of additional heat to the RV.

Before I took it back I was going to go thru all the hoopla of trying to insulate the hose. And did a whole bunch of searching on the internet, thought I'd share what I found with you.

For those that already have a portable in your RV or house:
Here is good link to a product to buy to insulate the hose that worked and didn't look tacky! Hope it helps.:C

I have a portable to help our 12.5k a/c cool our trailer which is 31' of living space on very hot, humid days. It's an inexpensive 8000btu single hose that I vent out the rear window. I've never run it on it's own but I'd be willing to bet if we closed the bedroom door it would cool the living room/kitchen area just fine on it's own. We've only run it on low as that's all it takes to keep the temp from creeping up during the afternoon. I have a thin plywood insert I made that I install in the window and it has a little swing-out puck to run an extension cord to the 20amp outlet on the pedestal. But I've only had to do that at one park. We usually just plug it in one of our inside outlets. As far as the hose. It's a non-issue with mine. Yes if you put your hand on it, it does feel warm, but has no effect on cooling the room.
