Thanks for the answer.My question was the thickness of cores (AWG) - this I did not find in the spec.
The cable thickness do not give an information for that because it mainly depend on isiolation and shield.
According Kemper Manual a AWG24 cable should not extend 7,5 m .
With thinner cable the maximal cable lenght decrease.
How did you make a quick scan that it looks like to be able for up to 200 feet?
Yes... I was not able to find the exact AWG either. I submitted a request for information and willl let you know what I find out. With AWG, smaller is thicker. I believe these are much lower (better) than 24 AWG. Here are links to the 200 ft version. I only have experience with the shorter version.
