metal electrical box grounding screw
Several Journeymen have stated that if you run metal conduit, the conduit is considered grounded, thus a ground screw in every j-box is not required (the same answer applies if you're running MC cable). You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception .Inside each box, you terminate on the box's ground screw, a hole tapped 10-32. If the ground screw already has a wire on it, then either pigtail it so all grounds .
If a metal box is being used, best practice is to insert a green grounding screw into the threaded hole in the back of the box or enclosure. . After opening the outlet up, it appears that the metal box has no grounding screw and the existing grounding wires are wrapped behind the .The grounding pigtail connected to the electrical box can go under the green screw on an outlet or switch. The internal metal bonding strip from the BX cable is pulled over the anti-short bushing and wrapped tightly around the armor to .
In this video I will show you how to correctly bond a metal 4 square box. I want to be clear that you need to use a separate ground screw and a wire that i. There are a few different ways to ground a metal junction box. One is to use screws and clamps to attach the grounding wire to the box. Another way is to use a bonding jumper.

Technically speaking, yes. However you’re trusting that any fault current will run through the saddle (the metal bit of the receptacle) through either the screws holding into the box or by . Do not use sheet-metal screws. However, this may not be necessary. The device has metal tabs (ears) where you screw it into the box. Pay close attention - if the ears "bottom out" on the metal of the box, you do not . Several Journeymen have stated that if you run metal conduit, the conduit is considered grounded, thus a ground screw in every j-box is not required (the same answer applies if you're running MC cable). You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception that allows you to not satisfy grounding requirements if no grounding means exists for replacement switches.
Inside each box, you terminate on the box's ground screw, a hole tapped 10-32. If the ground screw already has a wire on it, then either pigtail it so all grounds can share, or drill and tap another 10-32 hole (e.g. with self-tapping screws). If a metal box is being used, best practice is to insert a green grounding screw into the threaded hole in the back of the box or enclosure. The equipment-grounding wires then connect to the screw, making the metal box part of the grounding system. After opening the outlet up, it appears that the metal box has no grounding screw and the existing grounding wires are wrapped behind the mounting screws (the box has two mounting bracket, one on the top and one on the bottom and each bracket has some space to the back of the box - see the picture).
The grounding pigtail connected to the electrical box can go under the green screw on an outlet or switch. The internal metal bonding strip from the BX cable is pulled over the anti-short bushing and wrapped tightly around the armor to keep the bushing in .

There are a few different ways to ground a metal junction box. One is to use screws and clamps to attach the grounding wire to the box. Another way is to use a bonding jumper. A bonding jumper is a piece of metal connected to the grounding screw on the box and then attached to the ground electrical system.
Technically speaking, yes. However you’re trusting that any fault current will run through the saddle (the metal bit of the receptacle) through either the screws holding into the box or by contact with the box and then to the bonding screw in the back. Steel has a higher resistance to electrical flow than copper which will create heat.
