Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.
What happens if I put a higher amp fuse?
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 replace a 15 amp fuse with a 20 amp fuse?
It would not be a good idea to replace a 15 amp fuse with a 20 amp fuse. If you do and you actually load to circuit to more than 15 amps, you will shorten the life of the insulation and increase the risk of a fire.
Can you use a larger amp fuse?
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 you use a higher amp fuse than recommended?
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.
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.
What happens if you put a 15 amp fuse in a 10 amp slot?
If you were to say replace a 15 amp fuse on your power outlet with a 10 amp it would work perfectly fine to charge your phone but will probably blow if you tried to run an air compressor. 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 is the safest replacement for a 20 amp fuse?
the circuit wire is sized for a 20A fuse. If you replace it with a 15A fuse it will not overload the wire and will blow when the continuous current exceeds 15A so yes you can safely replace the 20A fuse with a 15A fuse.
How many amps does it take to trip a 20 amp breaker?
Actually, a 20 amp breaker must trip at a sustained current of 27 amperes (135 percent) at less than one hour, and at 40 amperes (200 percent of wire rating) in less than 120 seconds—far differ- ent from what the cited text implies.
