what an absurd response!
For the willing: solid wire is intended for Ac because the current travels
thru the average of the thicknessas it alternates polarity. Dc travels on
the outside (skin effect) due to mutual repulsion of the electrons;
therefore stranded wire is best for high current loads of Dc. If the wire
is well supported and larger than necessary for the rated current AND
cheap enough vs stranded, then go with it. Otherwise, stranded.

Boats are wired with tinned stranded wire based on some solid

When you go to sell the boat the surveyor will note that the electrical system
doesn't meet ABYC electrical standards.

Stranded, captive terminals, and no wire nuts.

One argument against soldered connections is that the molten solder can wick
up into the stranded wire and stiffen the wire back to a hard spot which, being
concealed by the insulation, can fatigue without being seen.

Hmm.. Additionally, that's wrong.

1) Skin effect is of concern - but only at frequencies well above
those used for power transmission. Start thinking about it at perhaps
5 MHz up. Skin effect is actually absent at DC

[in response to another well-intentioned post from someone else...]
2) an equal diameter of stranded and solid power line passing equal
currents, shows the stranded line getting hotter, with more volt drop,
because the resistance per unit length is higher for stranded.

Please don't share knowledge with us, willing or not, unless you're
sure. There's always someone to spot a misconception.

Oh sure they will. You can either put the bare wire there, or fix a terminal
to the wire and fasten it to the screw on the side.

When boat manufacturers install 110v wiring in a boat at
the factory for the "house" 110v circuits (like lights, plugs,
A/C, tv, etc..) what do they use?



Stranded wire.

Note that the electrical outlets are different than the typical household
outlets as a result. An outlet that is designed for solid wire won't work
for stranded.

They are exactly the same. You just don't use the push in connector.
Use the screw terminals with crimp on ring terminals.

The marine grade electrical outlets that I have used all have a clamp system
for securing stranded wire. You insert the wire into the hole in the back,
just like the household units. But instead of it being a "one way" catch,
the screw on the side tightens down the clamp.

You have that backwards. Skin effect is an AC phenomenon. Here, check out
this web page from Institute for Telecommunications Sciences:
http://www.its.bldrdoc.gov/fs-1037/dir-033/_4923.htm

Note that skin effect is only significant at high frequencies. There is no
significant skin effect at 60 cycle per second.

I didn't know that. Why is it not safe? What problems can it cause?

Thanks - Dan

Cost of assembly. It gets the boat out of the door, and it works long
enough to last until the end of the warranty.


Power wires should NEVER be soldered. It's against NEC and NFPA code
for good reason. It's not safe.

NEVER solder an electrical connection within a vehicle or any machine that
is subject to motion or vibration. The solder creates a stress concentration
at the end of the solder, which in time will cause the wire to break right
at the joint. That is why it should never be done. Those that have done this
and not experienced a failure are simply lucky.

Ytter,
As a rule you should use FINE tin plated stranded wire. It should be
sheathed with either fiberglass or metal braiding. It can be ordered
from
an
industrial wire supply house. It cost more than other type wire, but the
overall cost difference at the job level is minimal. Just as
importantly,
you should consider the mode of most common failure of wiring. That is
corrosion at the wire terminal interface. To avoid the moisture
migration
cause, you should use crimp terminals without insulation and a crimping
tool
that provides enough pressure that the terminal to wire connection
actually
welds. Then shrink tubing is applied and after the terminal is installed
the
entire connection should be painted with a rubber compound. This also
can
be
ordered from the industrial supplier or directly from OMC.
