How can a fuse fail?
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. A mis-wired lamp, for example, can cause a short circuit and blown fuse if it is plugged into an outlet.
Why does my 100 amp fuse keep blowing?
I think a short to ground would cause the fuse to blow and the only major things in this system that is capable of blowing a 100amp fuse are the cables, alternator, 100amp fuse and the battery. I disconnected everything and I am not getting a short to ground in the cables.
Is there a max size for a 100A fuse?
( IMP/001/010 /3.5.3.1.) However ,if it’s not a full clip fuse & the cartridge fuse is only half clip you only get a max size of 60 Amp. The 100 Amp marking on the fuse carrier of the cut out block is in relation to the max size only, this ;if your DNO were to run their equipment at 100%.
Is there a max load on a 100A supply?

Kev where do you get the diversity factor 0.4, from? carl.
What to do if your car fuse fails?
Jump start the car, if it starts, it’s not the fuse. Run it and look at the amp meter in the dash, is it above centre, then nothing wrong with alternator. So get a battery tester and see if it’s holding a charge. If it’s the battery, hard luck, changing one is the ultimate pain.

When to replace a fuse in an amp?
When an amp blows a fuse (or fuses, for amps with multiple fuses), you should replace the blown fuse with a fuse rated for less current. Let’s take an amp that has two 30 amp fuses. If the OEM recommended fuses blow, there is likely a serious problem.
What causes an amplifier to go into protection mode?
If the amp powers up normally and plays at relatively low volume, the amplifier is likely in good working order and you can replace the temporary fuses with the OEM recommended fuses. Blown output transistors are the most common failure in amplifiers and are also the most common cause of an amplifier going into protection mode.
Why does the fuse keep blowing on my alternator?
Something keeps blowing the 100amp fuse that is apart of the cable system connecting the alternator with the battery. It blows when I attach the positive end of the battery cable.
