[RE-wrenches] Wire nuts

[Benn Kilburn]

The reason i'm asking is that the only time i have seen a short,
first-hand, in a wire nut, was because it appeared that one wire was pushed
down rather than binding with the other wire, which would have happened if
the wires were not held tightly when the nut was twisted on.  Also, it was
a stranded wire (that was pushed down) being connected to a solid wire,
which is acceptable, but care must be taken to do it properly.

Also, on all the Ideal wire nut packages I have, the instructions say to
twist the wire nut on until there are two visible twists in the wire.  I
suppose this is to ensure the twist/connection is sufficient to make a
solid connection and perhaps to keep the wires together if the wire nut is
removed.

The ones in this photo do not look like they were installed as per the
instructions, which brings how much attention was put in to installing them
in the first place.

I've always questioned the why wire nuts are cautioned against, especially
considering how many wire nuts are used in residential and commercial
jobs.  I'm sure if there was a legit issue with them then insurance
companies would insist they not be used, such as aluminum wiring?
