generator cable length

What's the maximum length of cable I can use to connect my generator to my Scamp trailer ? At extended lengths do I begin to lose power (I'm assuming so). I have 2 new `Kipor' 2000 generators. I run them in parallel when I'm running the A/C. Only one when not (i.e. - winter, springtime).

So I guess the obvious statement should be is that I'm trying to create distance between my camper and the power source.

I've also researched ways (YouTube) on how to soundproof a generator; enclosures, etc. My co-worker suggested setting up a three-sided `wall' (a baffle ?) around the generator, leaving the side facing away open; and also the top open. This certainly seems like the easiest route to take.

Any suggestions ?

The determining factor is size of cable and load that you will be running.
I suggest a drop cord that uses 10 gauge wire. That is good for 30 amps
and as to length a 100 feet or less will work out for you.

check American Wire Gauge table and AWG Electrical Current Load Limits with skin depth frequencies - at the bottom of the page is a calculator where you can plug in a wire size, run length, and load to figure out voltage drop. Anything more than a 5% drop is getting questionable.

The AC needs at least 110v and is happier with higher voltages (up to 130 VAC or so).

Also keep in mind that the plugs are often a major source of loss and trouble (keep an eye on their temperature with an IR thermometer)

I might suggest that, if you're in an area with other campers around, that you should keep the open side facing toward you if you're keeping your generators away from your camper. Why should other campers around you to have to deal with the noise your generator makes if you have it baffled in your direction?

I would stay with 50 feet at most and use 12 gauge. 100 feet of 10 gauge wire is one very heavy cord to haul around and handle. I have one that I bought, used once, and it now hangs on a hook in my garage and collects dust.

Noise is going to about the same whether the generator is 100 feet or 50 feet or 25 feet away from the RV and with a shorter cord you can get away with a lighter gauge wire.

Well.. As someone said the bigger the diameter (Gauge) of the wire, the longer the run.

Voltage Loss AWG

Looks like a good chart, For one thing it shows the loss per kilo-foot of TWO CONDUCTOR cable, so you don't have to remember to double the run, they did it for you.
