Only if you want to blow up the microwave. That will let 20 amps go through before the fuse blows when the manufacture is telling you 18 amps max. <<>> Yes, you can use the 20 amp fuse. At 250 volts 2 amps is no problem and you are not going to blow up the microwave. On a fault current the 20 amp fuse will trip just as fast as an 18 amp fuse.
NO! The use of a higher rated fuse than is recommended can cause the wiring to overheat and cause a fire. Use exactly what is required.
In most cases the size of a fuse is not critical and so changing from 15 to 20 amp will not effect anything - BUT the function of a fuse is to destroy itself before some more expensive component gets destroyed by too high a current flow. As you raise the current rating of your fuses you increase the chances of negating their function,
Yes you can. The critical thing is that amps match. All 250 volts says is that it will work up to that value. You wouldn't, for example, use a 20 amp fuse since that could allow higher currents than the microwave could handle. The fuse blows because of excessive current.
This is not a good idea to do. Sometimes just that little bit of extra current that the 45 amp fuse will allow to reach the 40 amp load might be enough to destroy the device.
Use the correct fuse and nothing else.
I have never seen a 4 amp fuse, only 3 and 5. The peak power draw and dump is when you switch on and off your TV. Try a 3 amp and if it blows when you turn it on, then no, your particular TV can't use a 3 amp fuse. Don't worry about this test, it shouldn't damage the TV and fuses cost so little.
NO! Using a larger amp fuse defeats the purpose of the fuse to protect the wiring in the circuit. This can cause a fire. Always use the correct amp fuse for that circuit.

fuse number 1 is 10 amp fuse 2 is 25 amp fuse 3is 25 amp fuse 4 is a spare fuse 5 is 10 amp fuse 6 is a spare fuse 7 is 20 amp fuse 8 is 25 amp fuse 9 is 20 amp fuse 10 is 5 amp fuse 11 is 5 amp fuse 12 is a spare fuse 13 is 5 amp fuse 14 is 15 amp
It is NEVER a good idea to use a higher value fuse. The reason for the 10 Amp fuse is that it blows at 10 amps which the wire and device being protected is designed to handle. If you substitute 15 amps and that amount of current flows in your device, it may destroy the device and other things in the path of the current.
This is a unclear question, and not easy to answer. In your fuse panal, their will be a range of fuses, from 5 amp, up to 30 amp. On your fuse panal cover, should be a digram of your fuse panal, and which amp fuse goes into which slot.
