How to Work With a BX Cable

Drill a hole slightly larger than the BX diameter through each stud the cable must travel through, then insert an open end of cable through each hole and run the cable to the location where you want electricity.

Leave a large loop between studs at each point where you want an electrical outlet, switch or junction box. This allows you to continue running the cable without cutting a new section while still ensuring there is cable to work with for each required location.

Bend the cable at each point you need a switch, receptacle or junction box and at the breaker panel, making sure to leave excess slack so you can still work with the wires. The cable will snap when bent, then use a hacksaw to cut the connected piece of shielding. Pull back and uncoil the metal sheath a few inches, then strip the ends of each wire.

Connect the BX to each junction or switch box with a BX connector, then attach each stripped end to the appropriate terminal on your switch, receptacle or breaker panel and secure it by screwing in the terminal bolt.

Cover the stud in front of the cable with a nail plate, then hammer the nail plate in place. This prevents nails from being driven into the cable and causing a fire.
