Depending on the source power supply voltage you may be fine with the 120' of #10 for the 30 amps. But it "depends" and generally you do not want to buy something for the "depends" case. As Ray said, you really need the #6 if going that far.


However, lets look at a practical application. I recently had circumstances that required 140' of power line. I made it up out of two #6 and two #10 cables (30'/50 amp+30'/50 amp+30'/30 amp+50'/30amp). The source power was a stable 125 volts. I was able to sustain a stable 118+ volts at my coach with up to 25+amp load. But I cheated with the 60' of #6.


My point is that if you have good power to start with the voltage drop is not necessarily a show stopper. But you need to consider it, for sure. ESPECIALLY if you are going to be running air conditioners.

Thank you for the insight.

The electrical cord came with an RV I purchased. I don't have any history of using it, or knowledge of who made it, etc.

No damage.

So, 30 amps is what it seems it will work for.

Price is now $125.

I made up some extension cords (two sections) years ago when I was parked about 100' from where I had to plug in.


I don't remember the wire size but it was either #4 or #6 wire.


The first thing I thought about when I read "120 feet" was how heavy this thing must be... until I saw the #10 wire.


My cord is in three sections, the first being the regular hookup cord for the RV. But I know for sure that if I had all three of my cords in one box, that sucker would be HEAVY, probably heavier than I'd really care to handle with any regularity or even to carry around onboard unless I thought I was really going to need it.
