Braking National Electrical Code ( NEC )
As i watched the video i relosed that guy's braking Construction Codes. One of them, when you fishing cable thought any floor or ceiling u must fire stop any penetration that was made. :coolUsing approved firestop methods and materials, such as special caulk, putty, wrap strips or fire-barrier sheets, can reduce risks to structures and their occupants. Sealing or firestopping openings where cables penetrate fire-rated walls and floors is an important aspect of cable installation and maintenance. When fire erupts in a building, small openings in fire-rated walls, floors and ceilings for wires, pipes, ductwork and other building components become open channels for fire and toxic smoke, endangering both a structure and its occupants.
