I am bringing the subject up because I feel it is a very important subject I would like to hear what some of you guys have to say about it When you do a internet search on this subject you good lots of different results And to be honest I just don't trust an internet search 2 something this critical a ground fault interrupter receptacle will not work without a ground I know I've been to several people's houses and their washing machine or electric stove wood shock them 99.9% of the time it was caused because of no ground or an incorrectly installed ground These are problems I do not want to risk in a RV Any knowledge on this subject would be greatly appreciated And by the way I know I should know this but I'd rather swallow a little pride and make sure everything is safe be warned i am good parrot but Dumber than a box of rocks |

this is what I have in my caravan. Here is another video. Not cheap but 100% needed. Hmmmm dunno if it will work on your 60hz 120v USA voltage. Cheers Caveman Mark Off grid eastern Melb |

That's interesting Mark, the stand alone inverter outputs have no concept of phase or neutral, the 230 vac output is fully floating just like an isolating transformer. Providing no one has connected an earth (frame caravan) to a pseudo neutral in the caravan switch board, then that seems to me to be pretty safe, any earth leakage RCD or similar device wont and cannot work in this situation. Cannot comment on USA wiring here. Cheers Mike |

Good Day Mark, Are you using a inverter in the caravan if so is the inverter a stand alone unit or , is the inverter hard wired to the caravan outlets,with either shore power OR inverter to be selected by a rotary switch. Another alternative is to use shore power, to charge the inverter battery bank and then use only inverter to supply power to the mobile unit . Some commercial inverters also control the maximium shore power that the inverter takes ie 10 or 15 amps. cheers john johnmc |

Hi John, the van is used off grid, out in the bush. The inverters output goes to the RVD then through to the van wiring. That is just a small 2800w HF unit, I didn't bother making one for the van. Cheers Caveman Mark Off grid eastern Melb |

renewableMark and others I thought about it long and hard the only way i can see to be able to do it other than RVD Is some kind of sensor on the ground that reads voltage and if it senses any voltage on the ground it will kick them inverter off And that's probably how that RVD unit work Thanks all you guys for taking your precious time and thinking about this subject for me be warned i am good parrot but Dumber than a box of rocks |

Actually if you look at the product applications it shows volts 110-240 50/60hz here Cheers Caveman Mark Off grid eastern Melb |

Good day All Ben almost all permanent inverter installation in mobile vehicles / boats that I can find have a single common earth point for both AC and DC cuircuits. As this is the first time I have tried to reference a web site , hope it is not ballsed up. check [EMAIL=http://www.projectboatzen.com/understanding-inverter-installations/] cheers john johnmc |

This works better John Click the hyperlink (globe with paperclip) then type what you want to appear, click ok then paste in the web address. Cheers Caveman Mark Off grid eastern Melb |
