Originally Answered: Can I replace a 20 amp fuse with a 15 amp fuse? Replacing a fuse with a higher value one should never be done, as the wiring may be exposed to currents beyond what they can handle. This can potentially result in a fire and thus defeats the fuse’s purpose.
What happens when you put a bigger fuse?
Possibly. A fuse is designed so that if there is a problem, then the fuse blows. By putting in a higher voltage fuse, it takes more to blow that fuse, which could result in the wires getting hotter/melting/starting on fire. Unless you change the wiring, just leave the voltage of fuses alone and replace a 5v with a 5v.
Can I use a 20 amp fuse instead of 15?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
Is it OK to use a bigger fuse?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.
What happens if you put a higher amp fuse in car?
If you replace a fuse with a higher amp one it will work but create an unsafe circuit. It could cause a failure of the device burn it up, start a fire. The fuse is designed as a safety device. It should not only be the correct amperage but also the correct voltage and fast or slow blow.
Can I use a 30 amp fuse instead of 15?
You MAY be ok with a 30amp in place of the normal 15, but you MAY also burn up some wireing, and/or the whole bike. In any case the work done needs a good going over.
Can I put a 10amp fuse in a 5 amp?
Possibly yes. It is possible to short out a circuit by overdrawing more than 5 Amp by removing the 5 Amp fuse and putting in a 10 Amp fuse.
What happens if I put a 20 amp fuse in a 15 amp slot car?
The 15 amp slot is designed for handling current upto 15 amps so if you put a 20 amp fuse in a 15 amp slot and draw a current greater than 15 amps there will be heating and other issues like molten insulation you can put a 20 amp fuse only if u know that u are not going to draw more than 15 amps.
What happens if you use the wrong amp fuse?
Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it. … If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill.
What happens if you put a 15 amp fuse in a 10 amp slot?
It would still blow when the current exceeds 15 amps but it would allow a much higher current to flow briefly, like a few seconds, so that the current surge from a starting motor would not blow the fuse. That would be quite safe and, depending on circumstances, might solve your problem safely.
Why is it dangerous to use the wrong fuse in an appliance?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
Can I put a 13amp fuse in a 3 amp?
No it won’t. The only difference would be the current that flowed under fault conditions. If the OP replaced the cable on his lamp to a size that could handle at least 13A under normal/fault conditions then he could leave that 13A fuse in place until rapture!
What happens if you put a 13amp fuse in a 10 amp plug?
The 13A fuse in place of a 10A fuse wouldn’t directly cause any problem – but then, if there’s a problem with the appliance you’re using, or if you plug in too many things and the current goes over 10A but under 13A, then under the new fuse the extension lead will keep working whereas the old fuse would have blown.
Is it OK to use a lower amp fuse?
Do not use a fuse with a lower rating– don’t put a 20 amp fues in a 30 amp circuit–because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.
