Not only correct but the only way to go in many cases... it
seems most on the NG are house wiring guys and applying NEC as
they see it in homes etc...but not of course in the industrial
In corrosive environments, stranded wire will corrode into the
crimmped terminal and around the wire, insulating the wire
from the terminal slightly causing it to burn, then fail..
Accordingly battery cable manufacturers most often solder
their wire into the crimped terminal ends.
This practice is seen pervasively in marine environments on
both low amperage control circuits, and on power circuits.
Use of solder on power circuit terminals however has many
problems, namely the solder melting out of the joint if the
wire warms too much...and extrusion of the solder under
compressive stress if screw connectors are used.. the military
specs some are referring to cover that aspect... but not the
Use of solder in an already crimped terminal serves to
increase the electrical contact area, thats good, and to
preclude corrosive gases, vapors and oils from the joint (by
wicking up the bare wire).... that is seen commonly be the
cause of failure in those situations.
For the last 100 years... and currently.... most if not all
controls systems and component manufacturers dip wire ends in
solder that are to be fit under screw head connectors... the
practice is at least 90% common.... thats with *control
The practice is not common with power circuits for the reasons
mentioned but is still seen in some situations (primarily
corrosive environments... anyone can purchase NEC approved
soldered connectors of course for those purposes... those are
also pervasively common, especially in the electronics

Not true. In corrosive environments (like your marine scenario)
standard non-gas tight connectors are not spec'd. If they are used,
they will corrode. A gas tight connector must be used, and that too,
would NOT require any solder.
The huge crimped terminal on a commercial battery cable is NOT a gsa
tight termination. What does get used gets soldered because that is
the only way they can give the termination SOME life span.
Yet not seen in ANY marine environment where the proper fittings are
used. Most consumer level crap won't have such overtly expensive
hardware in it, hence the "workaround", with solder.
If the wire warms to the melt point temperature of solder, then
there is a much larger underlying problem with the circuit or the
wiring design. NO circuit wiring should EVER rise to that temperature
in ANY non fault mode of operation. EVER.
It is not referred to as extrusion, it is called CREEP.
The military were the inventors of the gas tight crimped connection.
If the connection is gas tight, it will be vapor and liquid tight as
well. If it is not made using gas tight methods, then it is open to a
host of problems. Many of which solder still does not fix or address.
It varies from product producer to product producer as some of them
conform tightly to proper manufacturing specs and some do not.
That doesn't make those that do not "most if not all".
None of those will be crimp style connectors. It is either a solder
terminal or a crimp terminal... not both.
Hey Roy... the money is on the professional end of the
market... professional behavior will get you there... here in
SF a good controls electrician can earn 80 dollars an hour...
a house wiring guy maybe 20 max.
In your area is probably a similar situation... you have a
chance to learn and advance and have the money to buy hot cars
and houses etc.
You would find that way in life ends better all around than
the option you are demonsrating.
I don't need a seminar about professionalism from a fucking retard
that doesn't even know how to refrain from top posting in Usenet.
You're an idiot. This entire thread has NOTHING to do with "a house
wiring guy". Stop ringing your own bell, dipshit. You ain't "all
My god, you are one retarded fuck.
You couldn't assess what is said in these groups if your life
depended on it, you fucking know nothing retarded bastard.
The fact that you requoted the entire post under the total tripe you
wrote proves that.
Read the part just after the beginning marked "TOFU".
You need to learn how to conform to the conventions of this group you
so readily invade, you stupid fuck.
There is a big difference between free speech, and posting like a
goddamned retard that has never been in Usenet before.
If you had half a brain, you would be able to see that they have
been just as abusive. Just because someone doesn't have the balls to
use an expletive doesn't mean that they aren't spouting insults.
Then there is the issue of them not knowing what the fuck they are
talking about. Where are your posts to them for the same thing, and
those from you to them about how stupid their knowledge of electronics
Also, this groups isn't about agreeing with someone. It is a very
technical group, and their FUD doers nothing to help that. One
doesn't foist one's retarded opinions on a group that is about facts.
Tell us, oh guru of knowledge... where do electrons flow in a wire?
It is either FACT or FUD, and his bullshit is FUD.
And it is you who try to teach us the conventions? I just hope there are not
too many susceptible children learning these conventions from you. Maybe you
have a pact with some anti-social gathering, what kind of rebel are you? Do
you plan to use your 'knowledge' of electrical engineering to melt the White
House? Maybe you plan to cause a short circuit in the Pentagon's power lines
and run in shouting 'The President is a fucktard retarded stupid dick' while
kicking your legs around and waving a copy of some goofy comic book like Viz
around in the hope the Civil Servants will succumb to your superior
iuntelligence and wisdom and give you control of the Senate and also the job
of rewiring the place. With luck someone will plug that 4000 volt cable you
have shoved up your arse into a supply cable capable of charging you with 20
amps. lol, I just hope they publish the pictures when they do.
All one paragraph? You're an idiot. I hope you are not trying to
teach your kids anything about the english language, jackass.
"iuntelligence"? WTF is that, asswipe?
You also show your knowledge of electronics to be about nil.
"charging with 20 Amps"???
You're an idiot.
OK, so it looks like what I did is not good (soldering the stranded
wire before connecting it to the screw terminals on the outlets).
However, instead of changing all the wire or getting outlets that work
better with stranded wire, can I solder on connectors like these:
And then connect these to the screw terminals on the outlets? Can I
just solder these on or is there any special crimping that needs to be
done to these? Do I need a special crimping tool or are these usually
made to work with normal pliers.

IMO, all the same problems will still be present, even more-so,
since with that, there is no J or shepherd's hook to help hold
the wire in place.
If you can't cut/restrip the wires,
FWIW, I think I'd simply pick up a cheap solder-sucker (spring
type, not squeeze-bulb), and clean as much solder off as
possible. Then using a moistened cloth, heat/remove the rest of
the tin coat as much as possible and put it back under the
screws. Watch out for melting the insulation!
The idea is to remove as much of the contact area solder as
possible. Wrap it on the screws & thightten. Info is provided
"as is" and with no guarantee of being acceptable or functional.
Personally, I'd cut/restrip the wires - and use a crimp-on
sized/made for the wires for connection. At the moment, that
soundss easiest/best to me, at least.
