50 amp pedastal/extension
What size wire should be used for a 50amp RV plug? I have an ample supply of 4AWG, 6AWG and 10AWG but no 8AWG. Is the 4 and 6 overkill? I will be visiting friends later and plan to park in their dr...

I installed a 50 amp outlet with 30 amp wire and 30 amp breakers. I have 7 RVs, and none of the 50 amp units use more than 30 per leg, so this configuration worked great. Just keep in mind that the maximun output per leg will be only 30 amps, any more will trip the breakers.
For all the ones that tell me that what I did is wrong, here is a kicker; I normally end up plugging a 50 amp coach in each one of the legs of the 50 amp plug (with a 50 amp Y adapter), all AC units running (in Florida summer) and never tripped a breaker or heat up the cables,
I am not going to tell you that you are wrong. However, it seems silly to me to go to all of the trouble if burying cable and not going to that little bit of extra expense to go all the way to 50 amp wire. If the need for true 50 amp power ever arises, you will have to re-do it. I only needed a 30 amp feed at my house, but I still used 6/3 wG and installed a 50/30/20 pedestal off of a 50 amp breaker. No matter what the future brings, RV wise, I am ready without having to re-do that job. Of course, I have always had the idea that I don't want just enough for now, I want enough for future uses too.
