Wiring in conduit

Running 3 #10's (stranded) in 1-1/2" PVC conduit. Total run 75 feet. Does
code allow me to have a splice within the conduit? Seems like it is kind of
accessible since I can easily pull it from both ends in case of problems.
Two 90� bends are involved but I am using long sweeps.

Thanks for the info.
BTW, while I'm typically not a cheapskate, on my retirement allowance I
would rather not pay for a new roll of wire ($65) when I'm only shy a few
feet. Buying a single 75' piece, by the foot, will still set me back $30.

All replies appreciated.

But if the situation allows, you could put a box in the right spot
and make the splice in there....

Or, again if it works, you could make one of the bends at a box instead
of the sweep...

Whatever, "pullable for access" doesn't equate to "accessible" per NEC.

Then your advice is worth exactly what the OP is paying for it. In many
places, the Code is _the law_.

Code violation, and, if underground, unsafe besides. Electrical codes are
there for a reason. Don't advise people to disregard them.

I disagree. Certainly one can make a successful splice in a potentially wet
location. This is done with deep well pumps where the splice is actually
under water. The difference is that a qualified person knows that there is a
splice down in the well, so if the pump doesn't work, a few tests can
determine the problem and the mechanic knows where to look for the open
circuit. If a person wily nilly makes splices in inaccessible locations,
where they're illegal as per code, who would even think to look there.

If there's no continuity from one end of the cable to the other, then
there's a break somewhere in between. Anyone would think to look there.
A well-made splice in the situation the OP describes is never going to
fail, anyway. And if it does, the length of wire is readily pulled and
replaced. Illegal? Sure. So what, says I. If you understand the reason
for the code, you understand under what circumstances you can ignore it,
particularly in your own home.

But that assumes that somehow you will always be there and available for
the life of the house. Standard practice makes tons of sense because
there is a common baseline and you don't have to scratch your head
because of corner cutting and hay baled work done by someone else.

Ditto. Unsafe, as I have seen with my own two eyes what happens when
water gets inside conduit and finds its way inside conductors (this
happened when the insulation was nicked when the wires were pulled).
Result was a corroded spot in the wire which caused an open circuit.

You are demonstrating your inexperience in your statement. For one thing
"your own home" becomes someone else's home at some point. True, one can
determine that the conductor is shorted or open, but when things are not
done by the book, it invariably takes longer to find the problem, since we
begin looking for the most logical location to find the problem. Another
thing, when multiple conductors are pulled in a conduit, they're pulled
together. In the process they get twisted around each other. Often you
cannot just "readily" pull a conductor out of the bunch. Sometimes the
"stuff" that accumulates in underground conduits acts as a glue, and can
make it difficult or impossible to remove the conductors intact, especially
if you've got some lump of a splice in there. Do it once, do it right. You
may have every right to muck up your own home, but I would refrain from
recommending that it's OK for others to do it

Personally, I like the idea of adding a box. In fact, I would add 2.
75 feet sounds like a long way to pull #10 through PVC, especially if
you decide later to pull afew extra wires, which I assume is the
reason for using such a large diameter.

Of course, if it's underground, that gets a little more complicated.

I'm pretty sure he wasn't disputing that. He just meant that no one
would ever know...

On the other hand, I do think it's a bad suggestion. He hasn't said so
yet, but I highly suspect that this is to go underground. If that
solder joint fails, damages the other wires and melts the conduit
someday, he's going to hate life when he has to dig it up and replace
it.

Code ain't for you. Code is for the poor SOB 20 years from now, and a
couple of owners later, trying to reverse-engineer what the hell you
did. Yeah, odds are an in-line splice would work, and if done properly,
would never fail. But how much would it cost to buy a long enough cable,
or put a proper junction box in the middle? Shortly after I moved in
here, I found a badly-done butt splice floating in the bathroom wall,
because previous owner was too cheap or lazy to run a new wire, all of
about 15 feet. Just recently, I discovered the 4' fluorescents in the
basement were hooked up above the drop ceiling, by shoving the ends of
the romex into duplex outlets wired into the octagon boxes that once
held the original porcelain fixtures. I still need to rewire those, so I
can have light in the basement again...

I'm not saying that splicing the wire in the conduit is dangerous, just that
it may become a nuisance to someone in the future. I probably costs less in
the long run to do things properly. You say, "let him splice the shit if he

Most. People are idiots, by and large. But it isn't up to me to judge
the skills of the OP. And if he misjudges his own skills, so what?
Freedom includes the freedom to shoot yourself in the foot.

All these damn rules and regulations about every tiny little thing that

terrified to break one of them now and again because they think they can
imagine some absolutely astronomical possibility that some catastrophe
could result, annoy me even more. Kill your family, someone postulated?

There are now "T-Tap" devices approved by the NEC, UL, and CSA for

I would never use them or advise anyone to use them, but they are
(currently) legal and available.
Aluminum wire and Urea formadehyde insulation were both legal and
available in the not so distant past as well.
However, the NEC has not (yet) allowed a splice inside a conduit.

Yeah, I know you're a code junkie, Doug. And I respect your knowledge
and your professionalism. And I understand the reason for the code. And
I realize that a hidden, inaccessible splice is a violation of the NEC.

Now, when was the last time you drove one or more miles per hour over
the speed limit? How could you possibly put your own life, and the lives
of your family, and the lives of children and other innocent strangers,
in such grave danger, by willfully violating a law that is designed to
protect us all from tragedies great and small?

If you think that a *properly soldered and shrink-wrapped* splice in a
wire in a conduit as described by the OP constitutes a *danger*, then
you and I define the word differently. I think the dictionary is on my
side, though.

I mostly agree with what you are saying. I think the OP however, is trying
to do the right thing as correctly as possible, which is why he asked the
question. I am not fond of our nanny society where everything has to be
built to protect us from ourselves, but imo, backed up by many years of
practical experience, the most practical, common sense solution, is to get a
longer piece of wire, then nobody has to be concerned about it's integrity
down the road

Irrelevant, because I do not advise people to exceed the speed limit. You
*have* been advising people to knowingly violate the NEC.

It certainly poses a greater *potential* danger than does complying with the
Code. The principal risk is water penetrating an underground conduit and
corroding the splice.

I dont know what the NEC says about soldering but its a bad idea.
Solder joints cant handle 20 amps of current unless they are made
extremely well. Ive known to many really fine electricians that
couldnt solder worth anything. Even a pretty good solder joint will
melt with 10 amps. Cycle the load on an off a few times and the joint
will soon have more resistance than the hair dryer someone had been
using on the circuit.

Almost all 75 feet is underground, ergo, I cannot add boxes. Am using
1-1/2" conduit because it makes for easy pull and, by the way, is only a

Well, actually, you can -- you just have to bring the conduit up above ground
for the box containing the splice, then back underground to complete the run.
Possibly it would be convenient for you to have a receptacle above-ground at
that point?

Absolutely.

BTW, if you're concerned about the cost of a full-length run of wire, keep an
eye out in your local newspaper for going-out-of-business sales at hardware
stores. When an Ace Hardware in my area closed a few years ago, I was able
to buy about a couple of *miles* of THHN wire (10, 12, and 14 gauge) for less
than a penny a foot. I may not ever need to buy that stuff again. <g>

Outside the already suggested obvious, then, you have one of two
choices--do the fully-right-code-compliant way or bite the bullet and
make the splice (on the assumption by the time there's a problem it
won't be yours to solve, anyway :) ).

If you do choose the splice route, just be sure it's made to handle the
underground conditions to be expected and sturdy enough mechanically to
handle the pull.

I had to repair a buried (no conduit) line to the well (wouldn't you
know that in an open area of a couple acres after eyeballing the run
from the pumphouse to the well I'd manage to set a post directly on the
run. If I'd been _trying_ to find it, otoh, I'd been all around.. :( ).
It's been almost 10 years so far w/ no problems so it can be done
physically; it's still not going to be code-compliant if that were to be
an issue (needing permits, etc., ...).

All in all, it would seem the extra investment in the wire is moderately
cheap given all else that must be going into the project (one assumes
there's something going on the end of the run... :) ).

Perhaps, even, one could get something back from the other wire via
Craig's list or similar to defray a portion of the outlay if $$ really
are _that_ tight...

I know that solder joints are forbidden on primary power circuits by
contract in many applications because there are reliabilty problems
with them. I also know that I have the skill to make such connections
reliably. In my job I dont keep up with the NEC anymore but I do know
that they were allowed years ago but thought that this would be
removed one day, this was a consideration back in the 70s because it
allowed on the skill of the electrican to make mutiple connections
without ever making a mistake. Used to, and Im paraphrasing a lot
because I dont have a copy of the NEC and I will take your word for it
that it is still allowed, the joint had to be of a quality where you
didnt really need the solder before it was soldered and the connection
must not rely on the solder for a circuit path, I take it this is
still true. I am sure you will let me know if it is not. The problem
is that solder will melt with just a few amps of current passing
through it. Once it melts and cools it may form a "cold joint" with a
high resistance. HIGH is a very relative term in this case as it may
mean conderably less than one ohm but much greater than the fraction
of a milliohm resistance of a good joint. These damaged splice would
work fine for years as long as the load on them was low but the first
time someone added something to increase the load on them they would
fail. In the 80s we had to remove all the soldered splices from our
wireways for the above reason, they were considered substandard. This
is quite different from the philosophy of the 60's when I was taught
that soldered joints were the acme of electrical splices and wirenuts
were a fire waiting to happen.

I cant think of a single reason anyone would want to use a soldered
joint for primary power wiring with the exception of what the OP
wanted to do and that was to circumvent other NEC specifications.

That has always been proscribed--NEC (won't quote Sections) prohibits
soldered connections in service wires, ground wire or a grounding wire.

Even where solder joints were prescribed, the solder was not to take the
place of the proper mechanical joint, only to maintain its integrity w/
time.

I've assumed (which I probably ought to correct) in another post to OP
that the run he's speaking of is a branch circuit and thereby is fused
upstream given it's #10 that would seem a safe bet.

Many years ago, soldering was used in house wiring. The
electricians used those big hunk of metal soldering irons
and if I remember, the things were not electric, they had
to be heated by a torch. The connections were insulated
by that old black friction tape. I come across it along
with knob and tube wiring in very old houses and buildings.

It wasn't that long ago. In getting my grandmother's 1961 house ready
for sale, I was changing out a crapped-out pull chain fixture in the
basement. Much to my surprise, the pigtail on the daisy-chain circuit
was neatly soldered and taped- no wirenuts. And this place was wired in
Romex, albeit the fabric-covered kind. I've worked on similar era houses
that had modern-style wire nuts (all black, of course, no color coding
in those days), so this must have been an old electrician near the end
of his career.

I wouldn't recommend a spliced connection in conduit. I don't believe code
allows it, but even if you made a successful soldered and insulated splice
that section of the wire would be "stiff" compared to the rest of the
flexible wire. It may make it more difficult to pull the wire through
conduit bends, and if the splice is not "mechanically" as strong as the
wire, you could pull the splice apart when pulling the cable. You would
never know if there is damage to the splice until you have an electrical
problem. For example, say a portion of the splice breaks but leaves a
strand or two of the stranded wire. It would work fine until put under
enough load to overheat the wire. This could melt the insulation on
adjoining cables and cause a short.

You didn't mention what this conduit run was for, but I suspect $30 for a
piece of wire is minimal compared to the rest of the project. Have you
compared the cost of the wire and conduit, against just running a bare UF
rated underground cable? If you're running conduit, you're probably
spending a little extra to do the job right and allow flexibility in the
future. Why cheap out on the last little piece of wire?

If you're REALLY strapped for cash, watch your local Craigslist for people
getting rid of electrical supplies, and/or post an ad that you're looking
for some. I sold a couple hundred feet of various cables a few months ago
for $10, and see contractors selling surplus all the time. There wouldn't
be any harm using a "larger" wire than you need (i.e. Using a #6 or #8
gauge wire in place of your #10), so that widens your options a bit.

If you're going to do the job, you might as well do it right...

Good Luck,

In aircraft use soldered connections are verbotten because solder
wicks back the cable and the cable becomes brittle - causing vibration
to break the wire. Same in industrial control panels. Not sure of NEC

That practice went out with knob and tube wiring. A "western union" or
"lineman's " splice was used. This was all well before a unified code
was in existance, IIRC.
Maximum load in those days was about 50 amps for the whole house -
with a "ring topology" meaning the load was shared over both ends of
the circuit - totally different system in North America today - with
single loads often exceding the total house load of years gone by.

And most of the early "wirenuts" had set-screws that clamped the wires
together, and the bakelite insulator cap screwed onto that - none of
the "twist-on" devices like today (the old "Marr "connector, vs the
"Marrette" today IIRC)

The set screw wire connectors are still available and
used for motor lead wires and other commercial equipment
that has to be replaced or repaired on a regular basis.
Back in the late 1980's I worked out on a Pacific atoll
and we had housing units that were manufactured in the
great country of Australia, they do funny things there.
The electrical wiring had connectors that resembles wire
nuts but had a small setscrew reached through a molded
in shroud on the side of the connector. The things worked
and were rated at a thousand volts because their house
wiring is 250 volts for a regular outlet. Oh yea, metric
Edison base light sockets, off just enough so that the
standard American bulb would not easily screw in. The
toilets swirled in the wrong direction too.

Well, I guess I'm that 10 billionth person. Had an outlet go dead,
started troubleshooting, traced it to a break somewhere between a
particular junction box and the outlet. This was on a circuit in
conduit. I just said what the heck, let's pull this wire out and
replace it since I don't know what's going on. Pulled the wire out
and found a splice in the middle of the conduit. Someone decided to
save 10 feet of wire and splice two 5 foot pieces together. The
splice failed. Replaced said wire and everything was fine.

Last time I looked at UL508A, which is the UL standard for industrial
control panels, it didn't say anything about solder.

"Wicking" only happens with stranded wires. It is not obvious to me that
a soldered connection is less reliable than a wirenut connection when
exposed to vibration.

The NEC appears to prohibit solder for connecting ground wires in a box
(250.148-E - "solely" is not entirely clear). My recollection is you
can't solder connections for the wire to system grounding electrodes
(GEC). Other than that I am not aware of NEC prohibitions on using solder.

Solder was used into the BX days. The wires were twisted first. I
believe the splice was pointed down and a solder pot was lifted to
immerse the connection. I have seen 2 failures of soldered connections,
one in K&T, the other BX. Both were "cold joints" - the wire did not
bond to the solder. Soldering, when done by a competent installer, is
probably at least as reliable as wirenuts. It is much less convenient,
not cost-effective, and a major PITA if you have to rework the connection.

In a poorly made splice it certainly will. If there is not a good
copper to copper contact the solder will melt. The NEC does or did
make this clear.

It is true that the resistance of the solder can be considered 0, but
that doesn't keep the temperature of the wire from getting hot under
an overload. The overload doesn't have to be caused by a bad splice.

WTF does an overload have to do with it? You can't just go throwing
random faults into the discussion on a whim. If you've got an overload
that's heating up the wires beyond the melting point of solder, and you
haven't tripped an overcurrent protector somewhere, you've got worse
problems than melted solder.

Jimmie says that more than two amps of current through solder will melt
the solder. Are you in his corner on that or not?

An overload has everything to do with it.

Are you suggesting that random faults don't occur?

Not really. I have seen suggestions in this very group that it is ok
to go ahead and use 14 gauge wire on that light you want to put at the
end of a run that is fed by a 20 amp breaker.

Yes and no.

2 amps of current might melt solder on those printed circuit cards you
use, but it would be negligible on 12-14 gauge wires that are used in
houses. It would take something like using a toaster oven and a Fry
daddy on the same circuit. That could bring the wire close to a
temperature that would melt solder. A short circuit (random fault)
would for sure. That is why the NEC requires splices to be
mechanically secure before using solder.

It is obvious when you ask the question......will 2A melt solder...
you really don't understand what is going on.

It's obvious to me that you're choosing not to follow the conversation,
and to change things to suit your own perversions. I do know what's

yourself that I don't. Even Doug the NEC junkie told Jimmie he was flat

Can 2 amps of solder melt current in house wiring. No

Can 2 amps melt solder.....yes.

Take a test lead and put it on one end of the solder and put 2 amps of
current on it. Keep extending the length of the solder.

You don't agree Doug?

Please show me where I said 2 amps, I'll send you a dollar.. Yes the
NEC permits soldering but unless you are extremely competent at it its
a bad idea. Where I work we have 3 very capable electricians one with
32 years of experience but I know for a fact none of them can make a
decent solder joint. They were never taught how. It is no longer a
required skill in any electical training program I know of. Back in
its day you flunked your apprenticeship if you couldnt make a proper
solder joint so yes those were good connections.My grandfather was a
master electrican who later ran a depot for the railroad( not sure if
that was a promotion or not) but he taught me to solder a splice. I
must have soldered a hundred of them to have him tear them apart even
though after the first four or five they were all good splices.
According to him that was the normal training method of the time.
Anyone on this NG that has to ask whether they can use a soldering
joint is going to to get a resounding NO from me. I figure those who
are truly competent to do it have no need to ask. The same applies to
anyone asking to bend the the rules of the NEC.

To quote your own words: "It is obvious ... you really don't understand what

That is *not* why the NEC requires soldered splices to be mechanically secure
without the solder. The NEC requires that because solder lacks the strength
necessary to make a connection mechanically secure.

The discussion was in the context of soldered splices, not infinite lengths of
solder being used as circuit conductors. (That's a Code violation too, BTW)

That simply isn't true.

That isn't true either. If a soldered joint can be "ripped apart" as you
described, then it wasn't properly mechanically secured -- which means the
joint wasn't any good *before* it was soldered.

And the NEC requires splices to be "mechanically and *electrically*
secure without solder" before they are soldered. It is probably not
possible to make a splice mechanically secure without it being
electrically secure. The solder does not carry the full current. There
is very little solder that carries any current. There are a huge number
of soldered splices out there that have not been a problem for over 50
years. I have never seen a failed solder joint that was not defective
from the start. If soldered joints were getting even a fraction as hot
as claimed the insulation would be destroyed. The NEC allows solder to
be used because a properly soldered splice is reliable.

Totally irrelevant to the discussion. A soldering iron generates heat by
passing an electric current through a heating element, and it should be no
surprise to anyone that a heating element designed to get hot enough to
melt solder will in fact do so. The claim under discussion was that passing
electric current through *solder* -- specifically a soldered splice -- will
generate enough heat to melt the solder. And that claim is complete nonsense.

Wrong. If solder is needed to prevent the joint from working loose, then it
was in fact *not* "mechanically secure without solder" and therefore was not
properly made.

Hi,
If soldering job is poor or/and the wire was undersized. It can melt and
separate. I 've seen it many times in my working days. You can make any
kind of splice between two piece of wires; soldering, mechanical
crimping/clamping, twisting together. wire nut..... If done properly all
works OK.
