5. POOR CONNECTIONS
This is probably the most common issue with caravan electrical systems because it covers a multitude of sins. Too many connectors on a single terminal, mixed metal contacts, corroded or tarnished connectors and bare wires in clamp-style terminals are just some of what we see in our Facebook groups.
While you could possibly forgive the DIYer for not knowing that some of these issues can cause problems, it is unforgivable for an electrician or manufacturer to make customers pay for this sort of sloppy work.
This is not how you organise multiple fuses.
If you have too many connections on a single terminal, it is nearly impossible to get enough tension to prevent it from loosening over time. When different metals come into contact with each other and moisture is present, electrolysis can occur. This can cause tarnishing of the surfaces, which in turn causes resistance. In severe cases, the metal can corrode and break away.
If you use bare wires in the connections of, say, a solar controller, the terminals can work loose over time. This can lead to arcing and carbon build-up. All of these issues will cause resistance and heat and, in extreme cases, fire.
