There is a plug in tester at camping world that seems to offer all the informatiom you need. Voltage Frequency Amps and polarity. It didn't say how many amps though. One thing though. Ant testing you do should be at the power pedestal BEFORE you hook your camper to it. That means you need to use an adapter to convert from a 30A receptacle to a 15A receptacle. The only problem with that .... John ... pay attention..... is that if the RV site's wiring or power is lacking, it will not show a voltage droop with any load. In other words, the voltage may read 120vac under no load, but after he plugs in and fires up the AC it might droop. He can find out by measuring the voltage before he hooks up and then again with the AC running at any 120vac outlet in his camper, assuming it is not powered by a converter. Usually the microwave and the AC are not run through the converter, so either of the power sources inside the camper could be checked. The voltage at the remote power setup I had in Florida used to droop to 105vac on some days. Bad for the AC compressor. That's why I bought the buck/boost transformer. That's a good point - didn't think of that. It's all about the load baby. If you turn the AC on, you should be able to tell if the voltage drops at another 120 Vac receptacle right? I'm sure somebody ha a device out there that you can load test a voltage drop. like you plug the thing in, hit a button and watch to see if the source electrical devices will hold current at the acceptable breaker amperage. The same thing I do with my Snap-on AVM tester. obsolete with the carbon piles etc, but it will truly tell you what batteries and charging systems are made out of. I've got one of these on my wish list now. http://www.campingworld.com/shopping...-monitor/24900 -- John H Great...then all you'll need is a competent person to operate it for you.

Generally, yes but some campers are set up such that some of the 120 vac outlets are powered by the converter and it's regulation may take care of droop. However, the high current draw items like the AC and the microwave are wired directly to the "shore" power 120v source and do not run through the converter. Some campers get all the 120vac from the shore power source. In that case, yes, any outlet will do to check camper voltage under load. Eisboch OK, I'm back to more stupid questions. If I've checked the voltage at the box, plug everything in, and turn on the AC, how can I then determine whether or not a given outlet is coming through an inverter or not? There is a 120v socket mounted in the sink cabinet. We plug the coffee pot in it. I guess I could measure the voltage, if any, when I'm not connected to shore power. Would that work?

You should have a circuit breaker for the inverter. Turn it off temporarily. With shore power connected to the trailer, measure the 120 volt outlet. If there is power, it is not running off the inverter. Eisboch |

Some use large capacity converter/inverters that can run many 120 volt outlets. Others, like the Sprinter we have, has a smaller inverter sized and wired to run a TV and DVD player only. If I want to make coffee and don't have shore power, I have to fire up the generator. It depends on how it was designed. In general though, campers that have an inverter (creates 120vac from the 12 v house battery) are not wired to run the AC unit and usually the microwave because those two components draw too much current and would require a large inverter. You really need to study the owner's manual to determine how your particular trailer is wired. Eisboch |

Most of the RV, camper tailer manuals are the same. You'll find out over time just by experimentation as to what runs off the inverter and what doesn't. You can also get faked out though. For example, we had a Chinook Glacier RV that had a super-dooper, relatively high capacity inverter. But, it also had a sensing unit in it that detected the presence of external shore power. If it existed, the inverter internally bypassed it's own output and distributed the shore power to all outlets (except the AC and Microwave). If no shore power was detected, it switched over to it's output to supply the same outlets with 120vac. It took me a while to figure out what was going on and I had to carefully study the supplied inverter manual to discover this. Usually the microwave does not run off the inverter and is not hardwired for power, meaning somewhere you will find it is plugged into a dedicated 120vac outlet. That would be a good test point to measure your supplied shore power voltage while the AC unit is running. Eisboch |

It's not likely you have and inverter. It would take a 2000 watt inverter to supply a single outlet. They are kind of pricey and if there happened to be one in your rig it would have been listed in your included options. Monitor your voltage at any convenient outlet. You will notice a brief dip in voltage as the AC compressor turns on. |
