![]() "Jim24242" wrote in message ... 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. Eisboch |

Eisboch There's a difference between "Droop" or sag and voltage drop under load. The sag can be detected without hooking up a load. |

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? |

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 |

The inverter produces 120vac from 12 vdc. The converter produces 12vdc from 120vac. Eisboch |

So in John's case, to be absolutely sure, he'd have to place a metered load at the source point to determine any voltage drop. Hmmmmm.... |
