# Question: Can I Use A Fuse With A Higher Voltage?

## Can I replace a 125v fuse with 250v?

You can replace a 125V fuse with a 250V fuse of equal amperage as long as the application voltage is 250V or less.

However, the reverse is not true.

You can not replace a 250V fuse with a 125V fuse of equal amperage if the application voltage exceeds the 125V..

## What kind of fuse do I need for 12v?

TYPES OF FUSES There are 3 types of 12v fuses I recommend. They are Spade Fuses, ANL fuses, and Re-settable Breakers. Spade fuses are the fuses that you’ll commonly find in your car’s fuse panel and are typically for items run out of your distribution block and less than 30 amps (in our case.

## What happens if I put 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 I use 125v outlet in place of 250v?

Example- Plug the 2 110/125V plugs in to 2 different rooms ran by 2 different breakers. … So by plugging the 2 5-15P plugs in to 2 different power sources it will make 220/250V from 110/125V. Or simply in to 2 different rooms in your house, as long as you get your 110/125V power from 2 different circuits this will work.

## Does voltage matter on a circuit breaker?

NOTE: The voltage rating of a circuit breaker must be equal to or greater than the circuit voltage. The voltage rating of a circuit breaker can be higher than the circuit voltage, but never lower. For example, a 277 VAC circuit breaker could be used on a 125 VAC circuit.

## 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.

## Can you use AC fuse for DC?

Even though AC fuses work well in DC circuits as far as fuse element melting due to over-current is concerned, they may or may not have same voltage rating for both AC and DC applications. … So even though AC fuses can be used in DC circuits one should look for their DC voltage ratings.

## Does it matter what amp fuse you use?

Fuses have different ratings so they can protect different electrical circuits. … A fuse that blows at 10 amps is no use in an electrical circuit that is using too much electrical current at 5 amps. The electrical circuit would be using double the ‘safe to use’ electrical current before the fuse blows.

## Can I use a 30 amp fuse instead of 15?

You MAY be ok with a 30amp in place of the normal 15, but you MAY also burn up some wireing, and/or the whole bike. In any case the work done needs a good going over.

## How many amps is a 250 volt fuse?

5 ampAmazon.com: 5 amp 250 volt fuse.

## What happens if you use the wrong 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.

## What happens if you put a 20 amp fuse in a 15 amp slot?

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.

## Can I use a 250v fuse instead of 32v?

250V is the max VOLTAGE the fuse can take, it is fine as long as that rating is at or above the VOLTAGE being passed through the fuse, in this case 32V. Fast blow can be used but will fail quicker, Slow blow fuses are designed to allow higher currents for a longer amount of time.

## Does the voltage rating on a fuse matter?

Yes, very important! The voltage rating of the selected fuse must be greater than or equal to the circuit voltage. Since fuses have such low resistance, the voltage rating becomes critical only when the fuse is trying to open. … For example, you can use a 500V rated fuse in any circuit that has up to 500V.

## Why does my 15 amp fuse keep blowing?

You have something drawing more than 15A. If it arcs and blows immediately then it is probably a direct short due to a component failing or a wire shorting to ground somewhere. The way to troubleshoot this is to disconnect all loads on this fuse circuit and then add them back one by one.

## Can I use a 10 amp fuse instead of 15?

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 use a higher 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 I use a 240v fuse in a 12v circuit?

If you use a 13amp 240v fuse in a 12v system will it blow when a 12v appliance drawing more than 156w (ie 12v x 13amps) is connected to it or does it require a 12v appliance to draw more than 3120w (ie 240v x 13amps) before it will blow.
