What will happen to an appliance if the fuse rating is less than the current an appliance needed?
If the fuse rating is less than the current an appliance needs, the fuse will likely blow or burn out. This is because the fuse is designed to protect the appliance from overheating or catching fire by interrupting the circuit when the current exceeds the fuse rating. It is important to always use a fuse with a rating that matches the current requirements of the appliance.
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.
Can you use a 32V 15A fuse if the appliance calls for a 125V 15A fuse?
No, you should not use a 32V 15A fuse in an appliance that requires a 125V 15A fuse. The voltage rating of the fuse is important for safety, and using a lower voltage fuse can result in the fuse not providing adequate protection and potentially causing a safety hazard. Always use the recommended fuse rating for your appliance.
What size of fuse is recommended to be fitted to an appliance with a rating of 1hp?
A 13 amp fuse is recommended for an appliance rated at 1hp. This will provide sufficient protection for the appliance and its components in case of a power surge or electrical fault.
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 is meant by ratting of fuse?
A fuse is given a various rating (strength). For instance, a home appliance (washing machine, etc) would usually have a fuse with a 13 amp rating. While a low powered lamp would only merit a 2 or 5 amp fuse rating. It is important to use a fuse of the correct rating in amps for each electrical appliance.
What size of fuse is recommended to be fitted to an appliance with a rating of 1hp?
A 13 amp fuse is recommended for an appliance rated at 1hp. This will provide sufficient protection for the appliance and its components in case of a power surge or electrical fault.
Why should a fuse of defined rating not be replaced with one with larger rating?
The fuse is rated to protect the equipment, the supply, and you. Change the fuse for a higher rating and you compromise your safety and equipment and supply safety; increasing the risk of electric shock and of fire.
Can a 13a fuse be used in a plug that takes a 3a fuse?
No, a 13A fuse should not be used in a plug designed for a 3A fuse. The purpose of the fuse is to protect the appliance and wiring from overheating and potential fire hazards; using a higher-rated fuse can lead to the appliance drawing more current than it is designed for, potentially causing damage or safety risks. Always use the correct fuse rating specified for the appliance to ensure safe operation.

Can you have a 15 amp appliance on a 32 amp supply?
Yes, providing the phase is the same. but you can't do the other way around, or breaker will immediately pop, or fuse will blow.
How does earthing of an appliance help in breaking up the fuse?
Earthing of an appliance helps in breaking up the fuse by providing a safe path for the excess current to flow into the ground, preventing damage to the appliance and reducing the risk of fire or electrical shock. If a fault occurs and the current exceeds the fuse rating, the fuse will blow to interrupt the circuit and prevent further damage.
What fuse would you use if you were fitting a new plug to a 2.5kw heater assume a voltage of 120v?
To calculate the fuse rating needed, use the formula: Fuse rating = (Power of appliance / Voltage of appliance) + 0.25. For the 2.5kW heater at 120V, the calculation is (2500W / 120V) + 0.25 = 20.83A. Therefore, you would use a 20A fuse for the 2.5kW heater at 120V.
How does a fuse wire save an appliance from high electric current?
A fuse link will melt and interrupt the flow of current to the appliance before it can get high enough to damage the appliance or wiring.
Will it work if you replace a 1.25 amp 125 volt fuse with a 1 amp 250 volt fuse?
Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.
