Because too high a voltage could arc across the fuse or could cause fuse to fail in other ways not related to normal operation.

What is the fuse rating for a kettle?

A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.


If a 10 ampere fuse blows constantly it should be replaced with 15 ampere fuse?

Most definetly not. If a ten amp fuse has been used to protect a circuit, then it has been rated by guidlines to be the most that that circuit can hold. If you put a 15 amp fuse in its place, you are effectively allowing more current to flow through the cables than it is rated for, which will lead to excessive heating in cables and possible fire. If your fuse is constantly blowing, it means there is most likely something wrong with the cables, like a short circuit. This is extremely dangerous. Call a qualified electrician to fix the problem


What is the fuse rating for a 400 watt appliance?

The fuse rating for a 400-watt appliance can be calculated using the formula: Fuse Rating (Amps) = Power (Watts) / Voltage (Volts). For a standard voltage of 230 volts, the fuse rating would be approximately 1.74 amps, so a 2-amp fuse would typically be suitable. If the appliance operates at 120 volts, the fuse rating would be around 3.33 amps, suggesting a 4-amp fuse would be appropriate. Always check the manufacturer's specifications for the exact fuse rating.


How many 100watt 220volts bulbs can be safely used in a circuit with a fuse of 5 ampere rating?

The current (ampere) changes from a high value at switch on to a run current of of approx 0.5 amperes. The fuse blows at switch on if too many lamps are connected. It also depends on the cable used to wire up the lamps and the length of the cable.


What us the rating of the fuse which is most Commondly fitted to three pin plugs?

If you are referring to the standard plug used in the UK, then the maximum rating fuse is 13 A, which can supply a load of approximately 3 kW. But the fuse fitted must match the power-rating of the load, so lower-rated fuses are available; for example, a 3-A fuse can supply up to about 700 W.

What does 5A mean in a standard fuse?

In a standard fuse rating system, the "5A" designation indicates a 5-ampere current rating. This means that the fuse is designed to safely carry a maximum current of 5 amperes before it will blow and interrupt the circuit. It is important to select a fuse with the appropriate ampere rating to protect the circuit from overcurrent conditions.

What does the AIR rating of a fuse mean?

The AIR rating of a fuse, or Ampere Interrupting Rating, indicates the maximum fault current that the fuse can safely interrupt without causing a failure or explosion. It is a critical parameter for ensuring that the fuse can handle unexpected short circuits or overloads in an electrical system. A higher AIR rating signifies that the fuse can manage larger fault currents, providing greater protection for electrical circuits and equipment. Properly selecting a fuse with an appropriate AIR rating is essential for safety and reliability in electrical installations.
