New to this site. Rather than search and possibly find, I'll ask... First Toy Hauler. 50 amp. But to visit the grandbabies, I'll have a 100' run, leading to a 30amp box. From the research I've done thus far, am I correct to assume that I'll need at least a 10 guage cord to run this length (8 guage bring preferred)? I know that I'll be limited on what I can draw. I'll start there. Thanks in advance.

If you plan to run the air I would go #8.

No penalty for a wire larger than necessary. Big problems when too small.

If you are not extending the plug, It's expensive but you could get 50amp extension cords and a 30 amp adapter at the plug.

What does "extending the plug" mean. My novice is showing, I'm aware, lol.

10 is fine for 30 amp, 6% drop 120v will equal 114 keep it over 108 and your golden, and this was at 30 amp not 22 where your ac will prolly live.

In TX, so A/C paramount. The "thicker" the wire, the closer to the 30 amp I'll stay. Fair to say?

as long as your over 108 it really doesn't matter how thick the wire is, at 30 amps the breaker will be your limiting factor and based on a 120v start voltage you well above 108, you won't be running 2 ac on 30 amp unless you have a energy mgmt system

Pay to have the kiddos system upgrading to 50a with oversized wire. Still cheaper than RV park after a period of time.

I schlepped around a couple of 100 ft cords for years for the sporting events I attend.

Until I found out Walmart sells the 30 amp and 50 amp extension cords! And they are not that expensive. I bought 2 of them. Makes it a whole lot easier to run a long distance and of course they are made to handle the amps.

if you are going from 50 amp to 30 or whatever, they sell every type of adapter you need. I bought every adapter for every configuration possible and keep them on board at all times. over the years I have used almost all of them to get to a shore station.

Ditch the extension cords and buy a couple of 50 amp or 30 amp RV extension cords and adapter to go down to 30. Get the ones with the handle of the plug end, you won't regret it.

Where there is a will there is a way to get power! [emoticon]
