Junction box grounding & pigtail questions

Please tell us how the Equipment Grounding Conductors (EGCs) from each cable is connected to the box. If that was not done with a reliable method then you will need to rework the box. If in doubt you should do a ground return impedance test using a Suretest or a good meter and a dummy load such as portable hair dryer. Unless you are fully conversant with the manual test technique you can actually start a fire attempting it so don't try to wing it.

Almost. Connect a short green, or bare, *solid* wire to the box, and use a wire nut to connect it to the stranded green pigtail from the dimmer.

Not possible, or not easy? :-)

Strip about 1/8" (3mm) more insulation off of the stranded wire than off of the solid wire. Twist the strands together. Put the wires side-by-side with the cut ends of the *insulation* lined up (so that the end of the stranded wire projects about 1/8" past the end of the solid wire). Screw the wire nut on good and tight.
