What is a fuse with a higher than required rating used in an electrical circuit?

A fuse with a higher than rated for a electrical circuit is used to handle spikes in the electricity delivered. Lets take a normal household wall socket. They are said rated at 120 Volt . They are in fact 115 V to 125 V a/c electricity @ 15 Amps.


In a 120V 24A circuit what amp fuse is needed to protect it?

A 30A fuse would be appropriate to protect a 120V 24A circuit, as fuses are typically chosen to be slightly higher than the circuit load to prevent nuisance tripping.


Is 700 amp for 500 amp OK?

No, a 700 amp fuse would not be suitable for a 500 amp circuit. The fuse amperage rating should be equal to or slightly higher than the circuit's maximum amperage to provide proper protection. In this case, a 500 amp fuse or slightly higher would be the appropriate choice.


Can you use a 600v fuse in a 120v circut?

No, it is not safe to use a 600V fuse in a 120V circuit. The fuse voltage rating should be equal to or greater than the circuit voltage to ensure proper protection. Using a higher-rated fuse can lead to safety hazards and may not provide adequate protection for the circuit. It is recommended to always use the correct voltage-rated fuse for the circuit.


Low volt fuse to high volt fuse?

I'm not sure of your question here. If you are asking if you can replace a fuse with a fuse with a higher voltage rating, the answer is yes, but it probably won't fit in the same terminals. The voltage rating must be the same or higher than the voltage applied.

What could happen if a blown fuse were replaced with one that blew at a much higher current than the original?

The circuit or device that the fuse was meant to protect would not be protected if a fuse with a higher rating were to be used. This could result in the circuit or device being destroyed by a higher than normal current flow in a short circuit fault condition.


Why is it not okay to use a fuse with a higher amperage rating in an electrical circuit?

The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed by this specific load. If this load malfunctions and the load current becomes higher that what is specified, the fuse is there to break the circuit. A fuse of a higher rating than what is called for will allow a higher current to flow through the circuit which could cause the insulation on the wire to melt, the wire to burn open or components in the circuit to become unusable. Never over fuse an electrical circuit with a larger amp rated fuse.

A fuse in a circuit is meant to burn out first if there is a short circuit. Should a fuse have a higher or lower resistance than the wire in the rest of the circuit?

The way current (series) fuses are designed and used, they are meant to overheat and blow and cause an open circuit if the current flow through these goes above the rated value. The resistance value typically is slightly higher than the wiring and adds marginal value of series resistance to the overall circuitry. The material characteristics of fuse ensure that at regular nominal current flow the fuse does not overheat, but when larger than expected current flows it overheats, melts (or gives very high resistance/open in a resettable fuse)and causes circuit to open.


Will a 240 volt lamp work in a 110 volt supply if the supply fuse size were increased?

No. The 240V lamp will pop the circuit or fuse because the draw is higher than the supply.


Why does a fuse blow?

A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.


True or False The voltage rating of a fuse can be greater than the circuit voltage?

True. The voltage rating of a fuse must be greater than the circuit voltage.


What is fuse what is it made up of?

A fuse in its simplest form - is simply a short piece of wire that is weaker than the circuit it is protecting. When the current flowing through the circuit exceeds the fuse rating, the fuse wire melts - breaking the circuit.
