How many amps should a low voltage fuse be rated for?

A low voltage fuse should be rated for 30 amps.


What happen when a fuse wire of 100 ampere is used when a circuit at home draws a maximum current of 20 ampere?

The fuse or breaker should be no bigger than specified for the wiring and devices on the circuit. Your nominal current draw may be 20 amps, but a short circuit would cause maximum current to flow which in this case would be 100 amps until the fuse blew.


Why does my 1875 watts hairdryer keep blowing out the lights?

If you are operating on a standard 120 volt system, 1875 watts will draw 15.625 amps. A standard fuse or circuit breaker is 15 amps. You are drawing more current than the wiring was designed to provide. The breaker or fuse stops that before you burn down the house. You need a smaller dryer, or bigger wiring.


What size fuse should you use to protect a circuit carrying 6 amps?

A breaker or fuse in an electric panel is protecting the wire, outlets and switches that are part of the installed circuit. You could plug in an appliance that draws 6 amps and have a 15 A breaker protecting the circuit. The idea for protecting a specific device is to put in a fuse that blows before the current destroys the device. If your 6 Amp device would be destroyed by 6.1 amps then you want a 6 amp fuse. However, fuses aren't that precise so this would be hard to do. A rule of thumb is that the steady state current in a circuit is 80% of the over-current protection. In your case this would be 7.5 amps.


How can a 30 Amps fuse for a shower of 9.5KW be replace with a 40 Amps fuse on RCD trip?

If the current safety requirement is 30 amps, you can;t run if off of a larger circuit breaker. It violates NEC and is very unsafe. If the current requirement is 40 amps , it will continuously trip a 30 amp breaker because it is too small of a breaker in electrical requirement.

What is the difference between a 3 amp fuse and a 13 amp fuse?

The difference between fuses is the current that they are designed to support. A fuse is intended as a safety measure to protect against overload. A 3 amp fuse should burn out if more than 3 amps is run through it, with some allowance for standard variance. A 13 amp fuse would burn out with greater than 13 amps. It is always a bad idea to use a fuse bigger than you need, because if your component is designed for a 3 amp fuse and you use a 13 amp fuse, there is a good chance you could damage your component with too much amperage because the fuse would not burn out at 3 amps, as was intended.
