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 size car fuse do I need?

Things could get really ugly really quickly, so to avoid all that mess you’ll need to ensure that you get the right size fuse for the job every time. 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.

Subsequently, What happens if you put a 20 amp fuse in a 15 amp slot in a 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 replace a fuse with a higher 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.

What happens if you use too big of a 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.

How do I know what size fuse to use?

The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10% to the value and choosing the nearest fuse to match. This is a more precise method then just guessing should you require a 3, 5, or even 13 amp fuse.

How do you choose the size of a fuse?

For example, if the normal steady-state current is calculated to be 10 amps, then a 15A fuse rating should be selected [10 amps x 135% = 13.5 amps, the next larger standard size is 15A].

What size amp fuse do I need?

The correct size of fuse to use depends on the amp you are wiring. If your amp has an internal fuse, then your inline car amp fuse should be a bit larger. For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse.

What happens if I put the wrong fuse in a plug?

If a fault in an appliance causes too much current to flow, the circuit can be broken. If something goes wrong, this protects the wiring. If the current is too high, the wire will melt and break the circuit. …

Can you put a higher amp fuse in a car?

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.

Can I put a bigger fuse in my fuse box?

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.

Can you put a higher amp 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.

Is it OK to use a higher amp fuse in a car?

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.

Can you replace a 10a fuse with a 15a?

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..

Can you use a bigger 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. … It is recommended to bring your vehicle to someone who specializes in auto electrical problems.

Can you put a 30 amp fuse in a 15 amp?

In fact, a 20 or 30 Amp fuse or breaker on a 15 Amp circuit becomes an armed fuse of a ticking fire bomb! … You replace it with another 15 Amp one. It blows again and again. Now you replace it with a 20 Amp fuse.

Can you use a 5 amp fuse in place of a 3 amp fuse?

If they have simply run out of 3amp then of course not. IMHO you must investigate why the device is blowing the three amp fuse if indeed the 3 amp fuse is the recommended value, it may have a fault. Simply changing it for a 5 because it is bothersome is foolhardy, and certainly not best practice.

How do I choose the right fuse?


How to Choose the Right Fuse

  1. Identify the type of voltage that is being protected. …
  2. Observe the amperage of the electrical circuit that the fuse will be protecting. …
  3. Size the fuse to its particular holder. …
  4. Inspect the fuse for internal element replacement. …
  5. Use a fuse that has an inspection window.

Can I use a 13A fuse in a 3a plug?

Don’t put the 13a fuse in place of the 3a fuse, the fuse blew for a reason.

What size fuse do I need for a 1500 watt amp?

A 2500 watt uses a 250 Amp fuse, while a 1500 watt uses a 150 Amp fuse.

Can I use a 13A fuse in a 3A plug?

Don’t put the 13a fuse in place of the 3a fuse, the fuse blew for a reason.

Which fuse do I need?

Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.

Can I use a 10 amp fuse instead of a 5 amp?
