Re: Lets talk AC again

If you are just experimenting, don't spend all the time and money building a wall... Grab a couple of these magnets and a good blanket or curtain and you have a good test wall. It is a bit redneck, but for testing and such it would get you a general idea and is fast and cheap.

I know most wont need it once your set up electrically but in the HVAC world a good multimeter is one of the most used devices for troubleshooting. Most compressors will have all the technical data that you will need to know about amp draw to see if your generator will be able to power it.
I never tried connecting my DVM to measure that. How fast is the startup current transient? I had assumed it'd be fast enough that a USD$200-grade DVM would miss it, or at least substantially under-measure it. The window A/C units I've looked at all had wattage information on a label somewhere, but I've had to peek through the louvers and hope to see the compressor's LRA. Never seen power factor marked anywhere on one.

Whaddaya mean I can't pull 1.21 jiggawatts through a single socket on my super-de-dooper genset?? You're right; many people aren't aware of the restrictions on how their genset is rated.

Oooohhh.. Thanks! I wonder in which direction are they designed to hold 20 lb, and how well they'll stick to a curve (the ceiling). Maybe you missed my notes about A/C testing I did on an earlier bus. I started with window A/Cs sitting on something.. a ladder or scaffold maybe, beside the bus.. and cardboard-duct-taped to the wall. In round two I removed a couple windows and hung the A/Cs in an OSB panel in the open space. Redneck mock-ups for testing purpose are absolutely acceptable! (but it might be intentional that you won't find any photo evidence of those awful-looking test setups!)

Re: Lets talk AC again

The 20lbs holds pretty well on the roof of my bus.... (holds a lantern anyhow) and it does take effort to remove. They have a 45lbs 1 as well... http://www.homedepot.com/p/Super-Mag...5#.UdkCKvnTogI If you are concerned about hold, I am sure the 45lbs will hold any blanket you got. Maybe set up a hammock for a small child with em when your tests are done.... I am sure you can find a use for a 45lbs magnet with carabiner, and we do expect pics. I can't read.... so without pics I don't know what you did.

Re: Lets talk AC again

Again this is why I LOVE this site.

#1.... good to see people close willing to lend a hand. Malkieri.... TY very much I sent you a PM so take a look there and get back with me.

#2 Redneck testing is always usually cheaper to pull off. There is nothing worse than getting something in nice and pretty then finding out it wont fit your needs. So all the ideas on here about blankets and what not a very good ideas.

#3 I think pics are a good idea. But I hope we have moved past that now days with as cheap as camera are that we can start rolling to video to start showing this stuff. I know you tube is a good way to go but that all depends on how its titled to be searched. Im not a huge digger of things on there but its a cool place to see what and how people are doing things.


Keep the info rolling. I think this is a good thread.

I can tell that you have a good, fast internet connection. I do not watch any online video very often. The long buffering times result in lack of interest. Not that it matters that some of us are internet disadvantaged. Some days I can barely upload a still image. Like I have been told elsewhere, I just need to spend a lot of money to get better internet service. It is just money and I can put it on my credit card. The one I refuse to get. Btw, we are on the campground provided wifi and I suspect some dimwit here is streaming video given the way the connection speeds are varying. Most of the time here recently, it's at 1mbps. Y
et my connection is excellant. Insensative clods!

Re: Lets talk AC again

Mine is not the best. When I moved I went from 30 megs down to 3 meg down when the traffic is not super bad. I know plenty of people who stop off at mcdonalds to borrow their internet and do such things.

Sounds like to me the campground does not know how to set up throttling in their router configuration.

Fight the good fight.

Re: Lets talk AC again

From what i have gleaned from this site and others......

a standard campground pedestal..... 30 amp service, is required to run a a single AC unit and your camper.

30 amps x 120 volts = 3600 watts generator

for 2 ACs .... a 50 amp service or 6000 watt genset

going smaller will overheat the wires!

hope that helps!

We plug into the 30 amp outlet on the pedestal. We are running the front ac unit, 6,400 btu, thru the breaker panel box. The rear ac unit, 5050 btu, is on a heavy duty extension cord that is plugged into the 20 amp outlet on the pedestal. We run both units during the day at the same time. At night the front unit is turned off. Only the rear unit runs at night. We figure that we will run the front unit while traveling.
