Electrical, Grounded Light Switch, With No Ground Screw/Wire - It looks as if the authentic installer did a quite sloppy activity of installing the cables (the damaged "redhead" insulating bushing pinnacle left is evidence of that"). That aside, the bx armor need to be grounded, so with the aid of extension, the field have to be grounded through the armor. In case you do no longer see a ground screw hole tapped, either the box does not have one (a few do not), you are no longer seeing it because you expect it to be on a dimple and it's flush, or the installer came about to apply that hollow for a mounting screw/nail.
I simply bought a ge z-wave dimmer and the i went to install it i noticed that the previous switch did now not have a ground cord connected to it. The brand new switch says that it calls for a ground switch (and obviously i want to put in the transfer appropriately). Is there whatever i can do to correctly floor it?. Most packing containers are tapped for a #10-32 screw for a floor screw because as a remember of conference and industry practice, that's what anyone uses. I consider the minimal screw size is #6, however -32 is the coarsest allowed thread pitch. That is due to the fact ul standardizes container thicknesses, and this assures enough thread engagement to be powerful. -40 is also allowed. A sheet metal screw is out of the question. A self-tapper is adequate if it's miles -32 or finer.
