Multiply the voltage by the amps and this will give you the maximum number of Watts you can place on the circuit. If your lighting circuit at home is protected by a typical 5 amp fuse you can multiply this by the voltage to get Watts. If you have to replace a fuse , it's essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating.
A common UK plug is generally fitted with a 3A or 13A fuse. Plugs for appliances rated up to about watts should have a 3 - amp fuse coloured red. The low voltage fuses are divided into five types such as rewirable, cartridge, drop out, striker and switch fuses.

The 13A fuse in place of a 10A fuse wouldn't directly cause any problem - but then, if there's a problem with the appliance you're using, or if you plug in too many things and the current goes over 10A but under 13A, then under the new fuse the extension lead will keep working whereas the old fuse would have blown.
A " 10A " fuse that is a fuse rated for 10 amps A stands for amps, a measure of current flow. A 10 amp fuse will be used to power and protect a circuit that requires a maximum input current of 10 amps. Fuses do not run normally at How to Change a Fuse Locate your car's fuse panel. Take off the fuse panel's cover. Locate the blown fuse. Remove the broken fuse. Insert a replacement fuse of the correct amperage—make note of the fuse panel and your owner's manual on this one.
Keep a few extra fuses of various amperages in your glove box. In some cases you may need a small screwdriver to unscrew the fuse holder cap.
Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced. If you cannot see whether the fuse is blown , follow steps 4 and 5. By changing the fuses to make them larger , all you would do is is make it so your amp could destroy itself if there was a surge of power, instead of blowing a fuse.
One common misconception about choosing the correct fuse size is that it's dependent on the load of the circuit.

Forum Cable Size for switch board wiring. What ever is wired into that 5 amp slot is rated for a max of 5 amps, overdrawing more than 5 amps by removing the 5 amp fuse and putting in a 10 amp fuse can possibly short out a circuit.
When a large wire is used, it enables a large current to pass through and damage the devices in the circuit with a limited current rating. That is why it is also quite unsafe to use larger wires with the fuse.
Moreover, oversize fuses are dangerous and should be replaced with the right size. For your fuse to do its job correctly and protect your wires, it should be rated about 1.
A 15 Amp circuit requires 14 gauge wire counter-intuitively, a higher wire gauge is actually smaller wire that can carry less current. Here if the current flows is between 15—20 amp, which is more than the rating of slot so fuse should operate but its a 20 amp fuse so it will not operate.
