What is the best way to terminate a live wire? I want to rewire a box that has 2 wire ungrounded romex with 12-2w/g. The problem is the box is currently recieving power from a box in an unknown location hidden under an attic floor and cannnot be disconnected. I could possibly put wire nuts on the existing wire in the existing box but that would leave the box very crowded. Any suggestions?
On another another circuit, I found the source but am not able to physically remove the disconnected wires from the box. Can I just cut off the disconnected wires or would it be better to put wire nuts on them?

To me, the phrase "America, Love it or leave it" is not very patriotic. Anyone can express the same exclusionary sentiment about thier country. I would rather say, "America, Love it or Change it".
