Can I replace a 12 amp fuse with a 15 amp fuse?

Can I replace a 12 amp fuse with a 15 amp fuse?

3 Answers. Never replace a fuse with one rated for a higher current. If you can’t find a 12A fuse try a 10A fuse. The fuses are to protect the wiring, not the downstream devices.

Can you use a higher rated 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.

Can you replace a fuse with a higher amp fuse?

CAUTION! 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 size fuse do I need for 12v?

If this is for general purpose power in a car or boat, I would suggest wiring the 12 volt cigarette socket to the battery with a 20 amp fuse in the circuit. If you use a 10 amp fuse, it may not be a high enough rating for accessories such as air compressors and power inverters.

Can you replace a 15 amp fuse with 20?

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.

Can you replace a 10amp fuse with a 5 amp fuse?

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.

Can I use a 10 amp fuse instead of 15?

good rule of thumb is: it’s alright to use a lower rated fuse in place of a higher rated one, but not vice versa. Not sure why it’d be blowing a 10 and not a 15.. there isn’t much of a difference…

Can a 15 Amp Fuse blow a 20 amp fuse?

A direct short circuit would blow either a 15 ampere or a 20 ampere fuse immediately. However, when you put in a 20 ampere fuse, and it doesn’t blow, while a 15 ampere fuse does blow, you are pulling more current through the wires than the wires were intended to carry.

What should I do if my Fuse has melted?

I’d remove the fuse, fix the problem, and put a 15A fuse back in, in that order. If not a fire, you’ll have melted wires soon and THEN you’ll have a short. At least you’ll know which lock solenoid was the culprit. The thing that’s a little scary here is that the power lock circuit is ‘hot’ even with the key off.

Where is the fuse on a Tim Ethe car?

The harness to the driver’s door is the usual suspect, becaus thet gets flexed repeatedly every tim ethe car is used. These types of shorts can often be found by removing the door panel, untying and “breaking into” the harness, seperating the individual wires, and checking continuity (in this case to ground) while flexing them.
