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 12v socket keep blowing fuses?

What to do if your fuse keeps blowing?
Don’t wiggle wiring harnesses around in hopes of getting it to not blow another fuse because then there’s no defect to find. Once it is in the defective state, insert a pair of spade terminals in place of the blown fuse, then use a pair of jumper wires to connect them to a 12 volt light bulb.
If the new fuse didn’t blow, an intermittent short caused the original blown fuse. An intermittent short can be difficult to find.
