I'm a little confused here.....

If you have three ground wire segments into a recepticle box (one
pigtail attached to the outlet, one coming into the box and one exiting
the box) and remove the pigtail from the outlet (where it's screwed to
the outlet) to service it, how is the continuity of grounding for the
rest of the circuit interrupted at all? Removing the pigtail from
the outlet still allows the wires coming into and going out of the box
to remain connected and thus maintain the continuity of grounding for
the rest of the circuit.


The original poster pre-wired the pigtail to the outlet. The major issue
is the grounds can not be disconnected to connect the pigtail.


Any why can't you turn off the breaker when replacing an outlet?

There may be different interpretations in different areas. In the three
states I am certain of, the ground continuity must be secured at rough
in inspection with listed devices in a manner unlikely to be
disconnected when a fixture is installed. In those areas, that usually
means crimping or using an approved grounding wire nut, either way
having a fixture.


Check out

http://www.ecmag.com/editorial_detail.aspx?id=1433

as an example.

It is explicit that a listed means must be used. An ordinary wire nut is
not mentioned (since it is not listed for such use). Crimp sleeves,
listed clamps and green wire nuts are among those referenced for such
use. "These connection devices are specifically listed for grounding
terminations."

An image of such is on

No, if someone can find ordinary wire nuts listed for grounding, please
post the reference.

One must keep in mind that the NEC always requires only listed materials
be used.
