If a fuse in your home keeps blowing it can be caused by several things. Most often it is because that circuit is being overloaded. There is simply too many things pulling power on that circuit. It can also be caused by a short in the wiring somewhere. Can also be an appliance is defective. Can also be someone has installed a fuse that is too small for the circuit. Whatever you do, do not install a larger fuse than the circuit calls for to prevent it from blowing. The fuse is there to protect the wiring from overheating and catching on fire.

Breaker boxes do not have fuses associated with them unless the main disconnect is independent from the breaker box. If that is the case both fuses have to be the same in the main disconnect that protects the breaker box.
No, fuse box fuses are of the screw in type. Plug in fuses are of a cartridge style that plug into the fuse holder which supports the fuse on either end of the cartridge.
The fuses and/or breakers in a home should be matched to the circuits. A qualified electrician can help you make the proper calculations. Do not attempt repairs or modifications if you do not have adequate knowledge about electricity or proper electrical construction practices. Mistakes can be fatal or at best, expensive. You can burn down your house or electrocute yourself or others.
An electrical fuse is not repairable. They have to be replaced with a new one of the same value as the one that is being replaced. Years ago there were one time fuses that had replaceable links that could be changed out if the fuse blew. Safety codes have changed and now these types of fuses are no longer allowed to protect electrical circuits.
