There have been a number of questions posted relating to how RV's are wired. I have put together a page that will hopefully answer most of those questions. This page explains the wiring for the four pin flat and 7 pin round 12 volt connectors as well as the 30 amp, 125 volt and 50 amp, 250 volt RV connections.
Please note that (at least in the US) there are only TWO wiring systems used for modern RVs. 125 volt/30 amp, and 250 volt/50 amp.
Have a look and feel free to forward it to others. Hopefully this will help dispel some of the misinformation that surrounds this subject. You will find it under "RV Wiring" under my index.
BTW, thanks to those on this forum that helped review the page for correctness. Special thanks to NHBob!
This needs to be posted somewhere for easy linking; any ideas how-to?

Thank you very much for the accurate and common sense details. When I first tried to wire my parking site at home for 50 amps. I received all kinds of erroneous information. The most noted was "On no, you can't run 220 to your RV, you will blow it up". And this was from a dealer service technician, plus other folks in the know?

Glad you found it of use. I think it was YOUR original question that made me decide a page was needed. I have had a lot of comments on it so far. It is amazing how much wrong information there is about the subject.
