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. -- Keith __ Nothing is foolproof to a sufficiently talented fool. "Rod McInnis" wrote in message ... "Michael Sutton" wrote in message om... 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. Rod |

I refuse to get into useless debates based on absolutely ridicules
assertions...so I'm going to stop right here and avoid the name calling that usually comes next. But I can give many examples that will prove the statement below completely unfounded. I solder all of the wires on trailers that I build (and I build a lot of them) and they are subjected to lots of movement and vibration and never fail. Sometimes the wires will get pulled apart but not the soldered joint. Huge numbers of soldered electronic equipment in high vibration service routinely last a lifetime without failure. The mechanical connection is far more likely to loosen, that's why we have loctite and NyLocks. Anyway, my participation in this thread is ended. It is obvious that Jax is more interested in "winning arguments" than in meaningful posts and in reading some of his past posts, name calling is next. "JAXAshby" wrote in message ... Would you mind explaining exactly how a solder connection fails "under high load conditions" when the connection is soldered it lacks mechanical integrity. solder is soft and any chance of movement -- any, even walking on a floor near the equipment in a building -- loosens the connection until it eventualy fails. Even if after soldering the connection is clamped TIGHTLY with a mechanical clamp it eventually fails. If the connection is FIRST clamped TIGHTLY mechanically and _then_ soldered for corrosion protection all if right and holy. |

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. Rod |

![]() "none" wrote in message news ![]() 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; 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. Rod |

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. Steve "QLW" wrote in message ... I usually solder connector on my boat and have never found this to fail. I've never see this done but the manufacturers so there must be some negative reason but I've not found it. "Steve Lusardi" wrote in message ... 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. Steve "Ytter" wrote in message ... I've heard different opinions what kind of wire is better for wiring boats.Could you give me some of your expertise? Thank You, Ytter |

Tom, you are incorrect. A solder joint under vibration can easily create a
resistive connection and it can be undetectable until it overheats. Please review my previous advice and use a crimping tool that creats a very high pressure crimp. Steve "Tom Shilson" wrote in message ... dazed and confuzed wrote: Cost of assembly. It gets the boat out of the door, and it works long enough to last until the end of the warranty. I agree. The crimp is for a solid mechanical connection. The solder gives a good electrical connection and resists corrosion. Tom of the Swee****er Sea |

If the connection is crimped first, you have it correct. Additional
soldering will create the stress concentration, which can fail slowly through minute cracks creating a resistive connection, which allows more and more circuit voltage to drop accross the joint. This heats the joint, and creates enbrittlement of the joint and wire and so on. This is not rocket science folks. It is common sense. Steve "JAXAshby" wrote in message ...

http://www.jamestowndistributors.com has pretty good prices on tinned marine wire. It's not Ancor brand, but the same spec. Also, our local Home Depot acutally carries a decent selection of marine stuff, including wire, nylon terminals, etc. Oh yea, while on the subject of terminals, be sure to use a good double crimp ratcheting crimper and good terminals. You can find both at http://www.terminaltown.com. They have all kinds of wiring stuff, including mil spec connectors if you're really picky! THe ratcheting crimper is the key. Properly done, a crimp connection is as good as a soldered joint. -- the most committed always win |
