Hi,

I posted a question a while back regarding whether it was code permissible
to ground
the green wire grounds in a gang box by using a single screw that was also
used to secure the
box to a wooden joist. Responses were that it was not, and you must use a
dedicated screw.
Good information.

One reply also said that:

"The code also requires that a suitable connector
must be used to splice the EGCs. just twisting them around each other
is no enough. "


IMHO:

Questions:

a. What's an EGC ?

Equipment Grounding Conductor. (the typically green or bare ground
wire).


b. does this mean that if I have, e.g., two green ground wires in a box, I
should twist them together with an Additional pigtail, put a screw
twist-type connector over them, and then just run the new single pigtail to
the ground screw ?


Sounds good to me!

What's wrong with just twisting together the two green ground leads and
running them together to the
screw (perhaps adding a small flat washer over them if the buildup looks a
bit large for the screw head) ?

Have to find it, but only one single wire loop under the screw is
allowed.

Adding an additional pigtail seems like a bit much.

This is why some people, strip back the wires and crimp them and cut
them so only one long conductor is left, and that is put under the
ground screw. There are 'greenies', wire nuts too.
