Here is an album with shots of how I used your mod. I will add to it as I use it more.

@ tmdart I like how you are using them.

Thank you. It is supposed to look like it is moving power, oxygen and hydrogen from the mass of mods in the middle of my base that is my reactor. It leads down to buttons that control the air pressure in the main room.

My solar facilty, still under construction but looking pretty good with these power cable blocks.

Wow dude. I like what you did with the cables. That was my original intent to run them underground so they don't take up lots of space in a tunnel. Thanks for sharing your screenies.
