[RE-wrenches] Wire nuts

Tue Sep 6 12:19:00 PDT 2016

Are those wire nuts listed for wet locations? Most ideal outdoor (damp/wet)
rated wire nuts are blue or grey in my experience.

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?

Jerry,

Can you confirm that this was caused by a failure of the wire nut, itself,
and not due to user error (not properly stripping enough jacket,  inserting
even length wires and sufficiently twisting on the wire nut)

To my fellow wrenches
It comes up every so often and with DC, I will not use, approve or pass any
wire nuts on any DC side. Some say its OK but the facts are they will fail,
this connection was just six years and when l opened the junction box it
was glowing and by the looks of it has for some time. There are 8 strings 2
per string and thats a 12.5 % failure rate (the other one was completely
distroyed) not to mention the fire hazard in a PVC junction box.
Please pass this along and tell everyone to stop using these.
Jerry
