When individual conductor strands are removed, the conductor shall be considered to be damaged. 10. When a conductor or cable has been damaged, or fails to pass an insulation resistance test, the conductor shall be replaced. 11. Duct tape, black electrical tape, or wire nuts shall not be used in the repair of a damaged conductor. 12. For terminations, no more than one wire may be installed under a single pressure connector, unless the device is listed for mare than one wire. 13.
