The device that the fuse is protecting is causing the fuse to blow. It could be in the conductors that feed the device. Disconnect the device and see if the fuse blows. If it doesn't, then the wiring to the device is good. If the device is a motor load it could be seized bearing that cause the problem. With the rotor stalled the current will go high and blow the fuse. If you know an electrician, see if the device can be meggered to see if the internal wiring has gone to ground and is short circuiting as this will also cause a fuse to blow.

What is a fuse rating?
Fuses have two basic ratings. The first is current rating. The current rating is the amount of current that a fuse will safely pass before blowing. When the current flow through a fuse exceeds its rating, it opens up and breaks the circuit. If a fuse has a 5 A rating, it will open as current flow through it exceeds 5 amps. It is useful to note that there are some fuses that are designated as time delay. These fuses will sustain current in excess to their current rating for a short period before blowing. The fuse that blows immediately when its rated current is exceeded is an instantaneous fuse. The other way fuses are rated is by voltage. So when selecting a fuse, be sure that both the current and voltage rating are suitable for the application.Fuse rating is the permissible minimal current to pass in the fuse element,without causing the fuse to blow or melt.
Why does the shared fuse for the lighter and power door locks on my 1995 Saturn SL2 keep blowing?
Most of the time this is a corroded or bad lighter. Disconnect the lighter and if it no longer blows the fuse, replace the lighter and lighter receptacle.
Which fuse is the fuse for the dash lights and the tail lights on a 1996 Ford Contor They both went out at the same time so you assume it is the same fuse?
Yes, on many cars the dash lights and the tailights are fused together. If it keeps blowing fuses, you may have a corroded tailight bulb. I hope this helps you. Mark could possibly be the headlight switch as well

What type of front must there be for a flood to occur?
A cold front as this causes a lot of rain in a short period of time. A warm front causes light rain for days at a time.
