Do you know what's Fun

melp64— WOW! You apparently didn't understand my point. Crimp and solder butt connectors are NOT the same. I am not endorsing the use of soldered-only connectors, regardless of whether they have heat shrink or not. As they say "your boat your choice". But, I wouldn't use them on my boat.

[melp64]

One of the reasons that I like this site is there are people willing to give ideas and reasons why. You are correct I know absolutely nothing about Marine wiring. I read on this site that the solder connector were great to use. Simply stating that the ABYC doesn't approve or is not the code leave a question as to why? So I did research and those that are following here is the reason
 Per ABYC (E-11.16.3.7), "Solder shall not be the sole means of mechanical connection in any circuit�". Further, crimping provides a solid mechanical connection resistant to "cold joints"� breaking under fatigue and removes strain.
With that answer it makes sense they want a mechanical connection because solder can crack from cold or movement. Now anyone that is reading this thread can make an informed decision. I have been using this forum to help refit my entire boat. The comments and information I have searched on this site has been outstanding. I hope that maybe someone will get something out of my learning and thanks to the folks that have help from this site
Noah your comparison between the two gave no reason to not use the solder only, and that's the point, if there is a solid reason state it for everyone to learn by. Had you stated solder might crack because of the cold solder or fatigue and this is why its code everyone reading would have gotten something out of conversation. Again the reason I read this site is to learn and help refit my boat, I am hoping to splash next spring but I know that I will have a lot more questions and will be reading this site for answers and help.

Mplp64:
Again you misunderstood(?) A cold solder joint has nothing to do with the ambient temperature of where your boat is located:

A cold solder joint is a defect in a soldered joint that occurs when the solder doesn't fully melt, resulting in a weak bond between the components. Cold solder joints can cause increased electrical resistance and may eventually lead to board failure.

I can second Noah's explanation of a cold solder joint.  It isnt ambient temperature, but rather the solder not reaching the appropriate temperature during the soldering process that creats a risck for joint failure.

Guys I got it I did the research You can beat the subject to death my point was giving a reasonable answer such as the code and good advice is what a lot of people come to this site for, If I have a question about anything I come to this site and start searching articles. I absolutely knew that it had nothing to do with the Cold weather in my typing I didn't put in the word solder so it says cold solder, I went back and edited it.

Melph64: I am not "beating this to death".  Just trying to clear-up any misconceptions of why soldering alone is not recommended.
This is what YOU stated (below) and is still how your edited post appears:

"With that answer it makes sense they want a mechanical connection because solder can crack from cold or movement"

Cracking from cold or movement is a misleading statement. Cracking FROM the cold is not what ABYC is concerned about. It is the integrity of a poorly done solder joint (aka, cold solder joint) and it being the only mechanical connection holding two wires together in a butt joint.

The secondary issue is that solder alone will creep whereas if the wire is crimped, solder wont fliw through the crimp.  Therefore potential work-hardening and failure of the conductor cannot occur were the stiff soldered and flexible tinnned-only wire meet.

Guys : I crimp and then solder, if for no other reason - it holds the connector in place so I can put my Weller D550 2.5A soldering gun on the joint!!  No cold solder joint with that gun!!   

A thought

Well I knew there would be some things on the boat I wouldn't be comfortable doing The electric was the first thing. Plumbing was the second but with doing things in pex made things a lot easier.
The electric I brought in a pro. That is one nice thing about running job sites is there is always someone that wants to help out. I had a electrician of 40 years come in help chase the wires and make sure everything that I had done so far was going to hold up. The PO had sliced and scabbed so many wires onto the back of the panel and then just hack them off. We pulled almost half a small garbage bag of wires that went no where. They had a lot of things wired with speaker wire. I don't have any speakers on the boat. We were able to get all the cabin lites up and running and the instruments by the wheel working.
Does anyone have a switch in the little cabinet in the head. Mine had a red switch like the one that is on the main panel but noting was hooked to it. I think the 110 power from the shore plug maybe goes to the switch and then to the main panel. because nothing was hooked up were guessing.
I have to admit it was pretty exciting to see lites on in the boat. Next weekend He wants to tackle all the 110 and check all the outside lighting like the bow and stern and see if we can get the light on the mast working.

Not OEM, definitely.

Glad to hear you're making progress in all the fun fields of play:  woodworking, plumbing and electrical.  Ain't life grand?
