air

im in san jose and today it got to 101deg. since the park where I'm staying only has 30amp hook up , so can't run both airs and one doesn't do it .i guess a gen.?????????????????

I can run both ac on 30 amp. Just can't run Micro, fireplace, Washer/dryer. All lights are LED and can still run TV.

johnboytoo · 05-14-2014, 02:48 AM

How about moving to a different site / park ?

It would be luck if you could run both, but try switching as much as you can to propane - (hot water heater, fridge) and shut down as much as you can.

Better plan would be to find a 50A site.

I wouldn't recommend running more than 1 ac unit on 30 amp. Although they might start up...they will overheat.

I was at a 30 amp only campsite a couple of weeks ago and ran both ac's with no issues. I have a surgeguard with the display each ac while running only pulls 12 amps each. Use propane for your water heater, don't use your microwave unless one is shut off, if you have led's like mine it doesn't matter how many lights you have on. Also I have the residential fridge have had no issues with it kicking on either. I don't see any issues with running it on 30amp as long as you are careful and don't turn on both ac's at the same time and they don't kick on at the same time.

I guess I don't understand, how would they overheat if they only pull 11-12 amps each? Also my display shows both legs and even with 30 amp it shows each of the ac's on a separate leg.

Agree, in SOME perfect conditions I might try it....

but not really wanting to replace electronics and ac's if anything else pulls more juice and creates a brown out condition...
running may be 11-12 amps, but what is the startup draw ? say if it's 20 amps for one and both happen to startup at the same time - that's too much...

A long time go when dual airs first came out,
there were kits that you could buy that would ensure only one would startup at a time, and it would cycle the ac's to allow 30 amps only...
but not sure if that is still around...

I'm so careful with running ONE ac that I will turn on the fan first, let it get up to speed and then turn the ac on....
and to make the draw as consistent as possible will leave the fan on constantly so the startup draw is as minimal as possible.

YRMV, but imho, I would move to a 50 amp site

The problem is.....although you might be hooked up to a 30 amp plug, if everyone in the campground is running their a/c units, you might not be getting 30 amps of power. I use a small cheep plug in device I bought years ago. This tells me if I'm getting enough amperage through the trailer. Many times in state parks on hot days, it's showing low amperage. With low amperage, the a/c units will start to over heat.

Your voltage can also be affected. It kind of goes back to the formula, VxA=W. If the voltage drops too low because you are drawing more Amps that can be provided, your circuit boards etc. in some of your appliances can be damaged along with other items.

atom ant · 05-14-2014, 09:11 PM

Just don't be the one the tries to run 2 ACs on a 30A service, and instead of blowing the breaker at the pedestal, you blow the breaker for the whole campsite loop... inside a locked cabinet.... on a holiday.... over 100 degrees

ahhemmmm - I can say you feel about as popular as the guy that didn't tighten the fittings on his sewer hose before he pulled the lever on the black tank

You sound as if you MAY have had many interesting and educational, uh, adventures. (Were you the guys responsible for the LA blackout of '96? No, wait, that was ME! LOL)

kshifter · 05-14-2014, 11:36 PM

wish i could98 here so far , only a/c , if do 2 pops the circuit... only 30amp what the say anyway

kshifter · 05-14-2014, 11:37 PM

1 ac running

kshifter · 05-14-2014, 11:41 PM

yes , I've tried 2 doesn't work, ... clean place and we like it here and close to work

Foxfire · 05-15-2014, 12:02 AM

I just got to the camper for the weekend. I started up both air-conditioners at the same time. Each air-conditioner draws 17 amps on the start up. They drop the volts from 122 two 119 on each line. The volts come back and the amps drop down to 15 and 16. they would definitely blow 30 amp circuit

I thought surge protectors only helped with lighting strikes and power surges. My husband said it also protects against low voltage and hot appliances. You electrical people...is that correct? We had a surge protector put on our RW before we brought it home.

We have the Surge Guard 50 amp built in and it protects against both high and low voltage - from memory I think it is 108 for low and about 130 for high.

There are some devices which only protect against a surge, such as might come from a lightning strike to the park electrical system or another failure. There are other devices which will regulate the incoming voltage, boosting it if it's too low (by "borrowing" from the amperage) and reducing it if too high. A few devices combine both functions. You should probably be certain of which you have. Hope this helps.

Also, some of the protections systems (especially built in units) have circuitry which monitors the voltage. If the voltage is outside a safe operating range, the power source is disconnected until the source voltage is back within a safe operating range.
