B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A. C Choose FUSE AMPERAGE near the middle of this range.

Beside this, Can I use a different size fuse?
A smaller fuse may always be used safely in a circuit; however, never use a larger fuse. Of course, if the current exceeds 15 amps, your fuse will blow.
Likewise, 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.
Also, What happens if you use a smaller 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.
What happens if you use the wrong fuse in a car?
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. Rather than risk blowing the circuit, take the car to a repair shop to determine what is causing the fuse to repeatedly blow.

Can I use a 15 amp fuse instead of a 10 amp fuse?
Yes, the 15 Amp fuse may be sized for a device in that particular circuit, and the 10 Amp fuse may be very short lived.
What happens if you replace a fuse with a higher amp fuse?
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.
What happens if you put a higher fuse?
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.
Can you use a 10amp fuse in place of a 5 amp fuse?
Possibly yes. What ever is wired into that 5 amp slot is rated for a max of 5 amps, overdrawing more than 5 amps by removing the 5 amp fuse and putting in a 10 amp fuse can possibly short out a circuit.
What happens if you use a larger fuse?
When a large wire is used, it enables a large current to pass through and damage the devices in the circuit with a limited current rating. That is why it is also quite unsafe to use larger wires with the fuse. Moreover, oversize fuses are dangerous and should be replaced with the right size.
Does it matter what size fuse is used in a plug?
For your fuse to do its job correctly and protect your wires, it should be rated about 1.1 to 1.5 times the rated current value. … Actually, the load of the circuit should have nothing to do with choosing a fuse size. The fuse size should be based on the SMALLEST wire (largest gage number) in the circuit.
What happens if you 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.
Can you use different amp fuses?
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.
Is it OK to use a higher amp fuse?
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.
Can I put a 20 amp fuse in a 15 amp slot?
A 15 Amp circuit requires 14 gauge wire (counter-intuitively, a higher # wire gauge is actually smaller wire that can carry less current). Unless you are 100% certain that all wire from the receptacle to the fuse panel is at least 12 gauge, you MUST NOT use a 20 Amp fuse.
Can I put a bigger fuse in a plug?
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.
Can you put a 20 amp fuse in a 15 amp car?
No. Here if the current flows is between 15–20 amp, which is more than the rating of slot so fuse should operate but its a 20 amp fuse so it will not operate.
