DC power supply unit fuse

When your power supply dies, it can mean that the fuse has been blown. Most fuses are soldered directly to the circuit board. Replacing them is a relatively straightforward process that requires remove the circuit board, unsoldering the old fuse, and soldering a new fuse in its place. The source is from a 48V forklift battery. Should I spec the fuse for the input. Do I need to put a fuse between each SBC and the power supply or DC-DC converter, or can I simply connect the SBCs? I have read somewhere that devices draw only the current they need, but I'd rather be safe than sorry. Welcome! Legally? Electrically? Are you ok with a single failure bringing down. The goal of this guide is a practi...
