Your 20-amp circuit keeps tripping because the fuse rating doesn't match the load. This Jaycar 20A yellow ATO blade fuse is the correct spec. It drops into your existing fuse block, holder, or panel with no modification. The transparent body means you can see the element before you seat it, and the yellow colour code lines up with every wiring diagram and parts list. Automotive, marine, and low-voltage DC applications all use this standard ATO format
