Quick Answer: Can I Replace A Fuse With A Higher Amp?

Can I replace a fuse with a lower amp?

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..

Can I replace a fuse with a higher voltage?

Therefore as long as the fuse amperage is sized appropriately and as long as your fuse voltage meets or exceeds your application voltage the fuse will safely protect. … You can replace a 125V fuse with a 250V fuse of equal amperage as long as the application voltage is 250V or less.

Can I replace a 7.5 amp fuse with a 10 amp fuse?

You will be fine with the 7.5a fuse as it’s the lowest denominator that will protect your car and in the end yourself if you ever blow a fuse. If you are using aux. amplifiers and not deck power, you’ll never pull more than a couple of amps. … If it blows, put a 10 amp in.

Can I replace a 13a fuse with a 5a fuse?

not it’s not. the device can’t take more than 5A that’s why it has a 5A fuse. if you put a 13A fuse in the device might take upto 13A before the fuse blows and more than likely you’ll fry it.

Can I replace a 2 amp fuse with a 5 amp fuse?

In the case of 5A fuse, the same will happen. It would be able to bear current supply ranging to 5 Amperes. Clearly, the size or specification of a fuse doesn’t affect its performance.

Can I replace a 15 amp fuse with a 20 amp fuse?

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.

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.

Can I replace a 15 amp fuse with a 30 amp fuse?

If you replace a 15 Amp fuse or breaker protecting a 15 Amp circuit with a 20 Amp or 30 Amp fuse or breaker, the next thing you should do is book your own funeral. … Too much current (or too many Amps) would flow through the wire and burn it before the fuse or breaker blows or trips.

Is using a higher amp fuse bad?

In general, NO. Replacing a fuse with a higher-amp fuse is a very bad idea and can lead to fires. Fuses (and circuit breakers) are rated such that they blow or trip before any part of the circuit gets to a dangerous current. … Fix the underlying problem, and you won’t have any more blown fuses.
