Grounding multiple devices in metal boxes
pigtail them.
The fasteners holding the straps on to the box don't count as ground, so the
straps aren't grounded
until you connect to the green screw on each one.

New devices come with a green grounding screw.....(not tlike the old
days)
I'm using metal boxes (metal conduit as well; either flex or emt)
but I also use a seperate ground wire that I screw to the box.
In a situation where I have multiple devices in a box (two switches & a
GFI outlet)......
Do I have to pigtail the ground & jumper to each device
OR
can the fact that the box is permanently grounded do the trick?
Room for the wires is no problem since I'm using DEEP "old work" boxes.
Thanks for the help.
cheers
Bob
