The safest way is to put the capacitors inline w your AC unit

Your trailer wiring is not rated for 50amps - yes - it will handle it - but say something goes bad - now you got a breaker that won't blow till it has plus 50amps on 30amp wiring - this is called a fire - and total meltdown of all the copper in your electrical system - every time your draw more amps than what your wire is rated for - you are fatiguing the wire and if they used aluminum wire to save cost and is probably the wrong size (aluminum needs to be double the size of copper) needed instead of copper - the wire will fatigue extremely faster --- I work with 100 to 200 amp circuits everyday bumped up to 150KV

Bring the start up amps down w capacitor kits - AC, Fridge fan ect --They are cheap and a much safer alternative than using adaptor to plug into 50amps

Be Safe - trailer go up in minutes when it comes to a fire

My 2 cents

Got a second bag in the microwave... love the Kettle Corn!

My EMS (Progressive) was shutting down somewhere around 103 vdc (don't know the exact spec), and the 30A in the pedestal was tripping as well... 4 or 5 times, while I was trying to watch TV; this with everything on electric. The temp when I set up in the CG was 105 and every MH and trailer there had ACs running, nonstop.

Going to the 50A adapter stopped the pedestal from tripping (of course), however this doesn't leave me vulnerable, because the 30A EMS was still in front of the trailer cord.

Similar to TURBS my line voltage then stayed above the voltage that would cause the EMS to switch the power off (technically it isn't tripping) and the pedestal breaker didn't trip again... not for the rest of the month. I looked at the voltage several times and it was never below 110 vac, but don't have any way to capture lows and highs. And, it let me keep everything on electric and stop burning my LPG.

I don't mean to stir the pot (yes, I do) but if breakers trip at the printed value, you would be resetting breakers every day, even at home. What it takes to trip depends on the current and the duration, like Herk shared. It will allow higher current than you might believe for a very short duration, but much less for a long duration.

Thats my story and I'm sticking to it. Pass the salt, please.

Using your air conditioner at low voltage (but above the EMS cut off) will cause damage over time due to the additional heat generated by the additional amps used by the motors.

It will also cause frequent air conditioner cut off due to the opening on the thermal breaker in the compressor. This cut out may save you from a fire, but it will eventually break down the varnish that insulates the winding wires causing motor failure.

It was over a hundred all week or longer. Other than get a motel room, die or run the AC the AC lost the toss.

Haven't "needed" it for 4 years untill Nashville.

This is all great information. Thanks for everyone's contribution. My choice of the word cleaner meant to cover the plug is less used, therfore makes a better connection.
I want to print as ll the good references mentioned.
Thanks

See Turbs you could have saved your self money if you stay up north.
Now I guess it's a good excuse to buy new camper and up grade ac. Later RJD

My confusion came from your use of "cleaner power" since that term has a specific meaning when talking about electricity. It applies to the "purity" of the signal and is most easily demonstrated when folks talk about the difference between "modified sine" and "pure sine" 120 volt AC power.

You can see from the image that the "pure" sine wave 120 volt AC power is "cleaner" than the "modified" or "square wave" power of cheaper inverters.

That's pretty much what progressive industries told me as I have stated here recently. Then he went on to say to check both if you only needed 30 amp service. Choose the best voltage to suit.

I'm just throwing some sarcasm in this disaster....

If there were two 30A plugs.. One was a loose connection and the other a solid connection. Would the result on the inside of the camper not be a "cleaner" uninterrupted AC current? How can you only talk about clean power upstream of the female receptacle? Wouldn't a loose connection disrupt your perfect sign wave?

I am going to stay at the Holiday Inn Express tomorrow night... So you know I'm right.

And PH was lookin' kinda skinny... Figured I'd keep his popcorn eatin' contest rolling....
