Quick Answer: Is It OK To Use A Lower Amp Fuse?

Can I use 5 amp fuse instead of 3 amp?

Yes, you can, but you have to ask yourself why the 3 amp fuse blew in the first place.

It might be that there was a transient and the fuse blew as it was supposed to.

Or it might be that something in the circuit is failing and replacing the fuse with a larger one will only lead to more damage..

Can I use a 2 amp fuse instead of 1 amp?

One can use a smaller amp fuse temporarily, but one should not use a higher rated fuse temporarily, as it could cause worse electrical problems or be physically dangerous. … A 30 amp rated fuse could be required because an inrush of current, for example, exceeding 34 amps might destroy what is behind the fuse.

Can I replace a 15 amp fuse with a 20 amp fuse?

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.

Why does my 15 amp fuse keep blowing?

If the cigarette lighter fuse is 15 amps, then a draw of more than 15 amps will cause it to blow. … And if the problem in your circuit is actually some type of short, putting in a larger fuse may cause the wiring to heat up to the point where it could melt or even cause a fire.

Can I replace a 10amp fuse with a 13 amp?

If you replaced it with 13A fuse, it will allow current more than 10A, so it may possible that other components may get damage due excessive current flow than specified. If TV components can sustain up to 13 A current, you can replace it.

Can I replace a 5amp fuse with a 13 amp?

A 13 will be ok in a 5amp device as long as its ok and your going to get the correct ampage soon. Not a good idea at all, if there is a fault with them you risk a shock or a fire.

What could cause a fuse to keep blowing?

What Happens When a Fuse Blows. There are two conditions that can cause a fuse to blow. First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through.

What happens if you put a smaller 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 replace a fuse with a higher amp?

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.

What is a 13 amp fuse used for?

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.

How much current can a 13 amp fuse take?

BS 1362 Fuse Operation Characteristics In fact a 13A fuse will allow a current of 20A to pass indefinitely without blowing.

Why does my 15a fuse keep blowing?

The fuse is the incorrect amperage rating Check what devices or lights are on that circuit, as it may be the case that a new amplifier pulls too much power, causing the fuse to blow. The more devices there are on one circuit, the heavier the amp load.

What happens if you use 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.

Can I use a 3 amp fuse instead of a 2 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.

Can I put 30 amp fuse in 15 amp?

That wire is rated to carry 15 amps. To carry 30 amps, you need 10AWG wire, and the Shadow just isn’t wired with it. Running 30 amps through the tail light circuit will eventually ruin your wiring harness.

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 size fuse should I use?

The fuse rating should lie somewhere between these two values to allow normal operation but blow on overload. For example, if the normal expected current draw is 10A and the cable size is 25A, then a fuse rated at 15A would be appropriate.

Can I use a 30 amp fuse instead of 20?

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.
