Jesus Christ, how cheap can you be? Go buy a pack of 50 red wirenuts
and 25 yellow ones, shove them in the guys face and tell him to use
them. You spent about $6 and saved your home and/or life. Also, when
it comes to adding an outlet or something later on, it will save the
next electrician 20 minutes of time to scrape the tape off.
I am the OP. I came, not looking for approval of/for something that had
already happened but expressing amazement that what I found -- black
hots and red hots (thus with 220/240 volts between them), with crimped
connections and a few layers of insulation tape -- could ever have been
I have remade the connections using wirenuts -- as I intended to do all

There is no indication in his posts that mechanical device or solder was
bilder99 was not looking for approval of what was happening. He thought
what was happening wrong and wanted a 'second opinion'.
Just curious. How do you which are which? I have never seen anything
printed on the packages. I have always twisted wires. That's how I
was taught many years ago. It's easier not to twist, but twisting
seems to make the best connection. As for wirenuts, I dont see how
twisting could weaken the connection.... (unless twisted so much a
It supposedly says on the package. I've never seen it.
Some wirenuts are apparently designed to do the twist while
you turn them on. Saves a little time/fuss for the electrician,
which is why they design them that way. It's remotely possible
that some wirenuts designed for "no pretwist" may (meaning
"probably only rarely") overtwist the wire if you pre-twist it
It's best to do what the package says, and err on the side
of pre-twist if it doesn't say.

I would avoid crimps for just one reason.
What if you had to replace an outlet, light fixture, or switch that went
bad, or wanted to upgrade to the latest and greatest fixtures or
switches? Would you rather just unscrew a wirenut, or try to get the
crimp off with a pair of pliers?
With many people, (especially with those who live in countries where
they are banned), there seems to be some sort of bias against the use
of wire nuts, even though they are a perfectly acceptable and an NEC
legally approved method of making splices. When done properly, by
twisting the wires together with a pliers and applying the wire nut
with a proper tightness, there is little chance the wire nut will come
off or that the splice will become a high-resistance hot spot.
Wire nuts offer the advantages of simplicity, economy, speed, and the
flexibility to make future changes without destroying the connecter.
Open up enough outlet boxes where the splices have been taped after 5,
10, or 20 years and you will, more likely than not, find examples
where the tape has dried up or even fallen off the splices it was
intended to cover.
I must admit to having been horrified the first time I saw a wirenutted
connection. Looked like some real Rube Goldberg affair. What I was used
to seeing for electrical connections was a box made of insulating
material, with firmly attached brass "busbars" with wires inserted into
the holes and held secure by clamping screws.
I have read that the wires must *not* be twisted together first. In fact
I just read a claim that UL approval of wirenuts depends on them making
a secure connection without pretwisting the conductors.
The ones I just encountered were likely original (30 years) and the tape

Is your first sentence in your paragraph above a conclusion you
reached from your second sentence, or was it a separate statement you
The seoncd sentence means that the wirenuts must be able to make a
secure connection if the wires are not pretwisted. It does not in
itself doesn't mean that the wires can't also be pretwisted. Or even
that it wouldn't work better if they were pretwitsted.
I only do this stuff once in a while, and sometimes I don't pretwist,
I guess usually when I don't have pliers handy, but I feel more
confidant of the electrical connection when it is pretwisted. Based
on my knowledge of things and materials and touching, I don't know how
it could be otherwise.
