Security and safety
All cables should have a fuse closest to the power source on the positive side.
When we at Skyllermarks train our retailers and talk about fuses, it is always the same thing. Stories about acquaintances and customers whose boats have burned due to the electrical system. Every time, we are equally saddened. It is money, hours of work put in, and dreams that literally go up in smoke. And completely unnecessarily, as well.
The risk with the electrical system
Modern electrical systems can deliver large amounts of energy. A healthy, well-sized battery bank can, in the event of a short circuit, release as much energy as if you were setting fire to a full liter of gasoline—every second. In that situation, it is not the time to start looking for switches.
Fuses solve the problem
If the cables are fused, it is the fuse that burns out and breaks the circuit before anything else in the boat does. It may sound inconvenient and feel expensive, but compared to almost everything else in the boat, it is such a small cost that it is foolish not to do it.
