Question: What Happens If I Put A Lower Amp Fuse?

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 should you never replace a fuse with one that has a higher amperage rating?

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.

How do I know if my outlets are 15 or 20 amp?

Look at your outlet. If the two slots are parallel, it is a 15 amp outlet. If one slot is ‘T’ shaped and the other is straight, it is a 20 amp outlet that will also accept 15 amp plugs. If the two slots are perpendicular the outlet is 20 amp only.

Can 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.

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

Possibly yes. What ever is wired into that 5 amp slot is rated for a max of 5 amps, overdrawing more than 5 amps by removing the 5 amp fuse and putting in a 10 amp fuse can possibly short out a circuit.

Can I use a 10 amp fuse instead of 15?

You can, it will may immediately blow, but it won’t hurt anything other than the fuse. … What you don’t want to do is use a higher amp fuse or something like a jumper wire. That could damage the wiring and start a fire.

Can I replace a 3a fuse with a 5a fuse?

If so, yes, you can replace a 3A fuse with a 5A fuse. … Thus it is unwise to replace a fuse with one which can carry more current. If you unwisely choose to replace a fuse with one with a higher current rating, first make sure that your fire insurance is up to date.

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

The real answer is NO. The manufacture put a 1 amp fuse in the unit because the typical draw is much less than the 1 amp and the fuse blow will be an indication of trouble coming.

Can you replace a fuse with a higher amp?

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.

Why does my 15 amp fuse keep blowing?

Having too many devices plugged into a circuit is the most common cause of fuses blowing. … Another potential cause of fuses blowing is a short circuit. When a hot wire touches either the grounding pathway or a neutral wire, it results in the circuit shorting out.

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 can you tell if a 13a fuse is blown?

Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.

Is it OK to use a 13amp fuse instead of a 3 amp?

For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted. … So for some appliances, the simple 700W rule may not work and they must be fitted with a larger fuse than the power rating would suggest.

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.

Is it safe to use 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 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. … You can put a smaller fuse in with the same “speed” rating.

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

Yup. The fuse is there to protect the wiring and 3 amp is well within the supply wire’s capability. Re: Radio calls for a 2.5 amp fuse.

Does it matter what amp fuse you use?

As a rule of thumb, fuses are rated according to the power rating of the appliance. … Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red).
