As the title says can you mix and match diff cable types?
For example say I have 4 power sources all outputting max 128 EU and I want to combine them into 1 line at 512 EU. I know I can just hook up gold cable to all 4 sources and meet them in the middle to 1 line and now that one gold line can hold all 512 EU fine, BUT.. can you say use copper wire from all 4 sources until you meet in the middle and then start using gold cable at the intersection.
