Up to about 20 Amps, a blade fuse is okay. Above 20 Amps use a link type fuse, which are bolted down at each end. Blade fuses are not suitable for currents above 20 Amps in a vehicle. Vibrations, moisture and dust cause the metal contacts to deteriorate, increasing resistance and potentially leading to fuse holders melting. Further, the cross-sectional area of a blade fuse’s prongs is much less than the wire it’s protecting. Worse still, the fuse holder contacts are weak and have a tiny contact area, resulting in loose or poor contacts. All theses factors generate heat due to resistance. A bolt-down midi, maxi or mega fuse is the best option. You get a solid connection and the fuse will have a cross-sectional area close to that of the cable it’s protecting.
