I've recently realized that I don't feel comfortable making wire nut
connections with threaded wire. I can actually make a mean connection
with solid wires that professional electricians commend me on. But when
it comes to making a connection b/w the solid wires and one threaded
wire (as in a recessed light) I feel that the threaded wire loosens the
connection. It makes me especially nervous realizing that the junction
box is getting covered by drywall.
What's the trick in making a solid connection with a threaded wire? Are
there special connectors that can take stranded wire? For example, I
like the spring connections on speakers, but perhaps that's not
permanent enough for 120v since springs fatigue...
Many thanks for your thoughts in advance,
What's "threaded" wire??? You mean stranded, I guess?
What's to commend? Put the wires together, put on the wire nut and twist...
_NO_ junction box should be covered w/ drywall.
No real trick other than there's no such thing as threaded wire... :)
Just make the stripped length of the stranded wire about 1/3rd longer
than the solid. I've not looked; I'm sure there's a blurb on it at the
Ideal or other manufacturers' sites.
If you want a little more insurance, you can use solder to tin the twisted
stranded wire to basically make it solid. Then combine it with the actual
solid wire and you stand a better chance of achieving a better mechanical
connection within the wirenut.
Thank you for all the responses and suggestions. Yes, I meant stranded wire.
But to everyone who no-no'd covering the junction box with drywall, what
do you suggest I do about this junction box:
I suspect this restriction is so the connections are easy to locate
if there is a fire. But, as a volunteer fireman, I can assure you that
during the fighting of a fire we are not going to be looking for a
junction box as one of the first things we do is shut the main power.
I think this is just another "feelgood" clause inserted by some desk
It is not a "feel good" clause, it is to ensure accessability to all
connections so that problems can be located, not just for fires, but for
maintenance and troubleshooting. They box may never be opened, but if it was
hidden how would you even know where it was is it needed to be worked on.
Oh, I'd probably look at a blueprint. Failing that, I'd probably use a
multi-tester and track to where a 120 suddenly shows a 240. Lots of
ways. Not to be obstinate but there is no really good reason to
preclude covering a box with sheetrock other than just convenience.
And, that's okay. But it is just a "feel good" measure.
The vast majority of the time there ARE no blueprints on existing homes.
You're lucky to even find a written description of wiring sometimes.
A multi-tester will not tell you where a buried, inaccessible
junction box is located. In fact, there is almost no way short of
expensive equipment to even locate it to within a few inches of its
The symptom would not be 240Vac; in a residential NA setting it would
be a loss of 120Vac 99.9% of the time. If it goes to 240, there is much
more wrong than an inaccessible junction box, which itself gives no
indication that it even exists, let alone where it is.
It's not covering a junction box with sheetrock that's a problem:
It's the inaccessibility of the junction box regardless of coverings
that is the problem. IF for instance the box were accessible from the
other side of the wall, ceiling, etc., then that's fine.
A "hot" junction box is not going to identify itself and in the hands
of a poor tech may result in an inability to even realize one exists;
while the house burns down that night. But if it's exposed it's easily
traced and found to be hot, by any competent tech with a current

The code requires junction boxes for splices to prevent fires from occurring
due to faulty connections, and requires them to be accessible, so
electricians can make repairs. OTOH, people who put out fires, tend to use
axes, not screwdrivers to do their job
PS: And just to show you how brilliant that desk jockey that included
that in the code is, short two 12 guage wires together in one of those
blue plastic boxes and see how long it takes to obliterate it.
I'm sure the desk jockey included requirements for circuit breakers that
would trip before the box got that hot.
If somebody piled confetti on a faulty connection carrying 20 amps, it
could reach kindling temperature. The box is intended to let that heat
I have the latest code book. 2008 I believe. Could you please point
out the page that tells me that the point in question was NOT inserted
by some desk jockey? If you can, I promise, I'll never help anyone
with house inspections.
Correction, I have the NEC 2005 (NFPA 70). I might have a 2008
handbook or something. But, just open up the front cover and read it
for yourself. Desk jockeys, mostly desk jockey's with nothing more
than OPINIONS! I mean, come on fella, can you give me a good reason
why a National Electrical Code would have a disclaimer of liability
for those that follow the friggin code? Geez. They sit around a big
room and all of a sudden someone says something like this, "hey, you
know what? My nephew, who once worked for an electricians helper, said
that it sure was inconvenient trying to track down those dang junction
boxes when they are hidden inside walls. Why don't you guys make that
illegal?". And as they've never seen an electric wire in their lives
say "sure, what the hell".
I can find a hidden junction box within minutes. With a magnet if it's
metal and with a multi tester (a bit more difficult) if it's plastic.
How hard do you think it is to trace from one outlet to the next,
along a wall? It's not foolproof but it's very doable. And once again,
if it's for safety, it's just a joke because I'll guarantee you, no
fireman is going to wonder around looking for junction boxes. So we
come right back to what I said originally, it's a feelgood reg for
