More proof you can't argue with an idiot that thinks they know everything.

They call me stoopid.

Q. Is it permissible to wrap a stranded wire around the screw terminal of a
receptacle?

A. According to the UL White Book under the RTRT category, stranded wire is
permitted to terminate to a screw terminal of a receptacle [110.3(B)].

For 18, 16, 14, 12, and even 10 AWG - Hell yes. We do it all the time in
the field. Terminals cost about 65 cents each. That is $650 a thousand. Then you need a$190 calibrated tool to crimp them. Now are you going to
wrap the wire around the screw or screw yourself?
Oh yes, you asked permission - Many contractors would send you down the
road kicking beer cans if you insisted on using terminals because some tech
writer put it in the UL white book. I actually know of a case where an
electrician was fired for using terminals!

I think this counts as a yes vote as well.

In the field, stranded wires in the 18, 16, 14, 12, and 10 AWG sizes are
often wrapped around screws to the right.

110 3(b) simply states that the manufacturers listing instruction shall be
followed. Section 110.14 also states:
Connection by means of wire-binding screws or studs and nuts that have
upturned lugs or the equivalent shall be permitted for 10 AWG or smaller
conductors.

110.14 Electrical Connections.
Because of different characteristics of dissimilar metals, devices such as
pressure terminal or pressure splicing connectors and soldering lugs shall
be identified for the material of the conductor and shall be properly
installed and used. Conductors of dissimilar metals shall not be intermixed
in a terminal or splicing connector where physical contact occurs between
dissimilar conductors (such as copper and aluminum, copper and copper-clad
aluminum, or aluminum and copper-clad aluminum), unless the device is
identified for the purpose and conditions of use. Materials such as solder,
fluxes, inhibitors, and compounds, where employed, shall be suitable for the
use and shall be of a type that will not adversely affect the conductors,
installation, or equipment.
FPN: Many terminations and equipment are marked with a tightening torque.
(A) Terminals. Connection of conductors to terminal parts shall ensure a
thoroughly good connection without damaging the conductors and shall be made
by means of pressure connectors (including set-screw type), solder lugs, or
splices to flexible leads. Connection by means of wire-binding screws or
studs and nuts that have upturned lugs or the equivalent shall be permitted
for 10 AWG or smaller conductors.
Terminals for more than one conductor and terminals used to connect aluminum
shall be so identified.

THE ANSWER IS STILL NO!!!!!!!!

Hey, retard boy... This is Usenet.

That means for HTML... The answer is NO!

The one caveat I would interject...

If the instructions that come with your receptacle specifically state to use
'solid' conductor's only, then no. The manufacturer's instructions should
*always* be followed. UL assumes that such instructions will be followed in
installation.

But if there are no prohibitions from the manufacturer, NEC states it is
allowed. And of course, if the manufacturer's installation instructions
specifically allow stranded wire, then of course the answer is 'yes'.

P.S. It is also important to note the wire materials allowed by the
installation instructions. Some receptacles are for Cu only, others Al-Cu.

So this vote is a sometimes.

That is not true if the listing specifically says the screw binding terminals
is suitable for stranded wire.

For heavens sake, read again what I wrote. I said 'if the instructions ...
specifically state to use solid conductor *only*, then no.' I further state
that you should *always* follow manufacturer's instructions.

Are you saying that 'if the listing specifically says the screw binding
terminals is suitable for stranded wire' you should *not* follow them? Who
died and made you king of the world? UL testing of equipment assumes it is
installed IAW manufacturer's instructions. If they say to use stranded wire
and you *don't* then you're wrong. If the instructions say either stranded
or solid is acceptable, then that's the truth, not some warped idea that you
have.

No what I am saying is if a manufacturer makes a receptacle or snap switch and
they don't support stranded wire under the screw terminals they can't say their
device is U/L listed. It is part of the U/L standard.

Okay, *that* makes sense. Sorry I was a little 'short' with you, but I
misunderstood what you were trying to say.
(RTRT for receptacles and WJQR for snap switches). They could pay for another
evaluation and category but nobody is going to do that when using the right
kind of screw is virtually free. It aslo makes the installation easier for
inspectors. If it is a U/L listed device, it is OK for stranded wire.
The red herring was when someone talked about any other screw on the device or
box not intended to be a terminal.. Terminal screws can serve no other
purpose.

Agreed!!!
