Fusible link alternatives

[BradW]

For higher current draw fuses you really want something that is bolt on. The fuse meltdown pictured above would have been caused by a loose connection which would have created a high resistance joint.
Extra resistance = extra heat = meltdown.
If you look at most late model vehicles, the higher current rated main fuses are bolted on to stop this problem.

Blade fuses are ok, it's just that the fuse holders like the ones that melted on me are not ok. They are cheaply made and that type aren't up to long term high current applications. The heat would have been generated by moisture or dust that made the connections slightly bad, which as stated above resulted in higher resistance and heat. The enclosed fuse holder didn't allow the heat to dissapate and it all melted. There are other blade fuse holder alternatives but they'll cost more.

The bolt on fuses I normally play with are rated for 500+Amps... mind you thats for 440V AC systems on minesites. Might look into a ventilated or open fuse holder, as it will be in a solid casing anyway.

the daihatsu one i mentioned is not really a fuse box... just two i think fuses next to each other, with a metal tab about 5cm to bolt onto something. wires bolt onto it...
can stick it anywhere cos it's so small and takes the relatively standard engine fuses...

Ive got a 100a circuit breaker on the altenator in my hilux.
