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 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.
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.
Can you use a 15 amp 115 volt device in standard outlet?
The outlet is connected to and protected by a breaker or fuse in a main electric panel. The outlet should be sized to the protection. Usually utility outlets in a residence are either 15 A or 20 A. If there are multiple outlets on a circuit then the total current cannot exceed the protection value of the breaker or fuse.

What is the meaning of the number 15 on a fuse or circuit breaker?
This is the amount of current that the wire in the fuse will "fuse" or open. and the Breaker will trip. Having said that, the time it takes to blow will depend on how close to the max the current is. If you put 13 amps on a 15 amp fuse, it will get hot enough to blow eventually. No fuse or breaker should have more than 80% load.
How many amps of electricity can a wire carry before needing a fuse?
ANY wire being used in electrical wiring requires over-current protection (a fuse or circuit breaker) so that the fuse will blow before an over-loaded wire gets red hot and ignites the insulation and any nearby combustibles.
What size Mini circuit breaker is the same as a 13 amp fuse?
13 amp breaker. A fuse and circuit breaker perform the exact same function so they should be the exact same size. They protect the wiring within a circuit from overheating and catching on fire. A 13 amp breaker is a superior product that has a good chance of operating between 13 and 13½ amps, while a fuse might not blow until the current reaches 15 amps.
14 awg copper wire for what size fuse?
You can use up to a 30 amp fuse or breaker with 10 Ga wire.

What is the best suitable component for circuit protection instead of fuse?
circuit breaker, or "resettable fuse", which is a reallya small circuit breaker in the housing of a fuse
What are the 3 things circuits and fuses protect against?
if too much current (amps, most similar to the volume of water in a river) flows throught the fuse, it will shed excess energy as heat, causing the wire to melt and breaking a dangerous circuit. the amount of amps is limited by the amount of amps required, so if + and - connect ALL OF THE CURRENT WILL FLOW, also heating and melting the fuse. some fuses and breakers have other capabilitites. breakers: a breaker, is a resetable version of fuse, when current gets too strong, the magnetism from a coil of wire pulls the breaker back open and breaks the circuit

What device protects an electrical circuit?
An example of a circuit protection device is a fuse. Another example is a circuit breaker.
How many amps are in a 110?
110 is commonly used to refer to the 120 volt, 60Hz electrical service found in the US and Canada. The current (measured in amperes or amps) is not related to the voltage so the answer is it cannot be determined. The amount of current that can be safely used in a circuit is determined by several factors, mainly the size and length of the connecting wire and the rating of the protection device (fuse or circuit breaker). Most 120V household wall receptacles are rated at 15 amps.
