Up until about 8 years ago, we used fuse boxes that had a separate fuse clamp and the tab that the wire connection screwed into. Under some circumstances they got corrosion between the parts, causing overheating and a bad connection. You can update with these. They can be broken into gangs of 4 fuses.
