NEC Article 520-2. Definitions. Bundled. Cables or conductors that are physically tied, wrapped, taped, or otherwise periodically bound together.

this is what i found in my 99nec..02 is with a friend.... so depending on ones IQ, there could probably be 36,482 definitions of bundling or more! LOL...NEC needs to address this big time, as well as many many other issues in the NEC ...why not put the def. of bundled/bundling in the front with the others?
