What to do when your fuse keeps blowing?
Try unplugging it and replace the circuit fuse. If the fuse blows immediately or activating the components switch causes it to blow, you know the component is good and you are instead chasing a wiring short problem. If on the other hand the fuse doesn’t blow, it suggests an issue with the component.
Why does a fuse blow when the current is too high?
The purpose of a fuse is to protect equipment and wiring against the damaging effects of electrical faults which cause excess currents, and to disable equipment which is faulty. The fuse “blows” when the current carried exceeds the rated value for an excessive time. The higher the overload the shorter the period before the fuse blows.
Can a fuse blow at 2 x its rated value?
Assume that a fuse will blow “after a while” at 2 x its rated value then we can expect it to run indefinitely at its rated value. If we have a household circuit rate at 20 amps and a number of outlets rated at say 10A then it is possible to connect more load that the rated fuse value.
