Hi Victor, I emailed Blue Sea about the soldering question and they responded. I figured they would have the AYYC rule handy. I know my shop and the other shops we work with never solder any connections.
Hi Perry, ABYC training recommends against soldering because there is a stress concentration at the point that the solder starts and in a vibration and flexing environment, the wire can break strand by strand at that point. Having said that, the rules aren't so rigid. In ABYC E11 (2003) it says: 11.16.3.8 Solder shall not be the sole means of mechanical connection in any circuit. If soldered, the connection shall be so located and supported as to minimize flexing of the conductor where the solder changes the flexible conductor into a solid conductor. There is a range of experience coming into this and for fast power boats subject to pounding and shock, or for engine connections such as to the alternator this is a serious concern. For a general connections in a sail boat, there may be less of an issue. The rules are not requiring it, but experience shows that using adhesive lined heat shrink on terminal connections in damp locations and using tinned wire can greatly enhance reliability. That is good practice, but not a requirement. Best regards, Wayne E.
