Electricians use the metal sheathing on the cable as an equipment ground wire and simply attach a wire from the ground screw on the receptacle to a green ground screw on . If the branch circuit wiring method was Armored Cable type BX (pre 1950s bonding strip), the BX jacket was the EGC for the grounding-type receptacle. The metal jacket of BX . The standard way is to fold the ground strip back onto the cable and use an approved connector (outside) to connect the BX cable to the metal junction box. Thereby the box will be properly grounded. Then use a ground . If the BX is properly installed, the cable's metal jacket should provide a ground path. BX should always be connected into metal boxes with the appropriate clamps so that the box .
BX cable can achieve grounding through the outer metal casing. This casing needs to be attached to metal boxes. NM cable's vinyl sheathing cannot ground a device, so a bare copper wire runs through every NM cable .
If the branch circuit wiring method was Armored Cable type BX (pre 1950s bonding strip), the BX jacket was the EGC for the grounding-type receptacle. The metal jacket of BX was NEC allowed as an equipment grounding means. BX cable is required when a metal box must be grounded to the cable's sheathing—NM cannot do this. Also, .

The ground wire does not need to follow the same route as the conductors, but needs to be installed consistent with code and generally in a workmanlike manner. In the relaxed rules in NEC 2014, you don't need to go all the way back to the panel if you can reach another circuit served by the same panel whose ground wire is thick enough.
