Fuses are a vital piece of safety equipment in any electrical system. Fuses protect the wire from an overcurrent event such as an electrical short or from trying to push too much power through too small of a wire. This blog post will teach you what type of fuse you need for your DIY camper electrical install.
Cheap vs Expensive Fuses
In the past, I’ve recommended very inexpensive fuses. They worked for a while and many people had good luck with them. Recently (since February 2020), both myself and the tech support team at Battle Born Batteries who I work closely with have seen an increasing number of quality control issues on these non-name-brand fuses that are so common on Amazon. These problems revolve largely around the fuse getting too hot under normal use. This would cause the fuse holder to melt, loosen, and cause the system to stop working.
So… if you wish to save some money and test your luck with these inexpensive fuses and fuse holders; that is your prerogative; but I can no longer recommend “no-name” fuses and fuse holders on EXPLORIST.life. So, the following list will include only fuses and holders from Blue Sea, Littelfuse, Bussman, Eaton, Spartan Power or similar that have, at least some kind of testing agency certification or code compliancy recognition (UL, ABYC, ROhS, etc).
