Subpanel Wire Questions
I am installing a 100 amp subpanel right next to my main 200 amp service panel for my basmeent re-model (both panels are GE). I've determined that I need to use 2-2-2-6 copper wire. What wire type do I need to buy? Also, if I buy four seperate pieces (as I don't think I can find a bundled wire) what do I need to do?

-Can I just run the wires from one pannel to the next through the wall? Or do they need to be protected in conduit or something?
-Can all four wires go through the same clamp at each pannel?
-I'll need to color code the wires with colored electrical tape, red and black for the two hots, white for neutral, and green for the ground? Can I color code the ground or does it have to been a green colored insulation?
-Is THHN wire appropriate?
-Anything else I'm missing?

Thanks for the help.

your wire must either be a cable or in a conduit. If you choose pipe yes THHN is acceptable. Because you must be either in a cable or conduit your wires will be in the same clamp/fitting. The ground must be green. The others are large enough that they are allowed to be phase taped. Be sure to keep the grounds and neutrals separate in a sub panel.

You don't need anything larger than a #3 copper for your hot lines; also a #8 is sufficient for the grounding conductor.

BUT IF you decide to upsize to a #2 for the hot lines, then a #6 ground would be required.

A short conduit nipple (I'd use PVC) is sufficient as well.
