Question: Does It Matter What Amp Fuse You Use?

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..

What happens if you use the wrong amp 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 amp fuse do I need for a cooker?

Electric cookers require lots of power to operate since they generate intense amounts of heat. This means that you need to get at least a 13 amp fuse, although newer models will most likely require a 32 amp fuse (read your product’s specifications to check its exact amp rating).

Can I use a 3 amp fuse instead of a 2.5 amp?

3 amp should be fine. the fuse is mainly there to protect from burning wires. you might try Radio Shack – they would have the fuse in a higher voltage rating (usually 250 volt), but that won’t cause a problem.

What amp fuse do I need for LED lights?

I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.

What happens if I 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.

How do I know what amp fuse to use?

Fuse rating = (watts/volts) x 1.25Note the power of the appliance – usually in the appliance manual,Note the voltage (240 volts in the UK).Use the next highest fuse rating after the calculation. Say the calculated fuse rating is 2.2679 amps, use a 3 amp fuse.

What happens if you use a 13amp fuse instead of a 5 amp?

not it’s not. the device can’t take more than 5A that’s why it has a 5A fuse. if you put a 13A fuse in the device might take upto 13A before the fuse blows and more than likely you’ll fry it.

Can I replace a 3 amp fuse with a 13amp?

If you have to replace a fuse, it’s essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating. A common UK plug is generally fitted with a 3A or 13A fuse. Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red).

Is it OK to use a lower amp fuse?

Replacing a fuse with a lower value one, however, is not unsafe but may cause problems if the load current is higher than the fuse value. It is thus generally recommended to replace it with a fuse of the same value. However, in some cases, it is probably okay to use a fuse with a lower value.

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 put a 13amp fuse in a 10 amp plug?

Most TV’s have a 2 or 3 Amp fuse inside. Fitting a 13 Amp fuse in a 10 Amp rated circuit may cause an overload or a fire. Fit the correct size fuse.
