Yes to add to that a little more. A mistake often used by people, is to use solder as a glue. The wire should be threaded through the recieving lug and folded back, or however the terminal is designed. Mostly, terminals are designed to hold the wire in some way till soldered. The solder is there to make an airtight electrical
connection between wire and parent material. At temperature, the solders properties are such, that they chemically bond to the surface of the other metal. Many metal types can be bonded to. Which is another important aspect in a marine environment
. Sometimes brass is the parent material used. It is asked to be crimped to copper wire. Thus two dissimilar metals. A high current
flowing through them and time and guess what. Solder stops that from happening. Plus in a crimped connector, you have little areas where water
can sit. I just replaced some crimped connectors on a Solar
panel the other day. They had compleatly corroded away. Most likely because water
had come in contact. I firml;y believe, that crimped connections should be treated with a water repelant electrical grease before crimping.
Then it is essential for strain relief. As I stated above, heat shrink is a good and easy method of doing such. But it has one other point to add to the picture. It also insulates the connection, so in the event of another wire ever breaking away,umm
then it should not be able to make contact with any other conductor. Accidents can happen. I fried an inverter
the other day, connecting it into a "monkey breakfast" of a panel. The main breaker was tripped to kill the power in the panel. But in my final connection, the output of the inverter
, brushed past the input connection to the breaker. Correctly installed and protected in the first place, the accident
would never have happend. Oh well.
