# Quick Answer: What Is A 5 Amp Fuse Used For?

## How many watts can a 5 amp fuse take?

Fuse ratings45 AMPFor circuits of more than 13kw (13000 w)13 AMPFor appliances between 700 and 3000w (3kw)5 AMPFor lighting circuits.

The maximum permissible load of a lighting circuit is 1200w or 12* 100 watt lamps3 AMPFor appliances up to 700 watts, such as table lamps and alarm clocks3 more rows.

## 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.

## 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.

## Why is it dangerous to use the wrong fuse in an appliance?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

## How many watts can a 16 amp fuse take?

Your MCB can hold up to 16 Amps and the voltage applied will determine how many Watts. The formula is simply Amps multiplied by Volts equals Watts. In the case of a 120V supply this means 1,920 Watts for a 240V supply it will be 3,840 Watts.

## Can I use a 5 amp fuse instead of a 3 amp?

Replace with the correct size fuse, if you are having a blown fuse problem you may have a short in the system. You can but you shouldn’t, it can cause wires to heat up and possibly cause a fire. You can replace a 5 amp with a 3 safely as long as you don’t exceed 3 amps. … If there is a short either will blow.

## How many watts can a 10 amp fuse take?

1200 WattsExamples: 10 Amps x 120 Volts = 1200 Watts.

## What is a 1 amp fuse used for?

1 AMP Ceramic Fuse are suitable for various different uses. These include providing a reliable performance and cost-effective circuit protection. They are ideal for use in plugs to protect cables from melting or catching fire if they are overloaded.

## How do I know what amp fuse to use?

You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. Fuse rating is the amount of current needed for the fuse to blow or break. When this happens, it stops the electrical power from flowing through the electrical circuit.

## Is a 3 amp fuse the same as a 13amp fuse?

There are two main types of plug fuse: the 3A fuse and the 13A fuse. In simple terms, a 3A fuse should be used for appliances rated at 700W or less, and a 13A fuse for appliances rated over 700W. … A 5A fuse is safe for appliances rated less than 1,200W. If an appliance using a 13A fuse is found, extra caution is needed.

## What amp fuse do I need for LED lights?

75mm is good for about 7.5 amps max. 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.

## How many watts can a 30 amp fuse handle?

7,200 watts30-amp 240-volt circuit: 30 amps x 240 volts = 7,200 watts.

## Can I put a 3 amp fuse in a 10 amp plug?

The 13A fuse in place of a 10A fuse wouldn’t directly cause any problem – but then, if there’s a problem with the appliance you’re using, or if you plug in too many things and the current goes over 10A but under 13A, then under the new fuse the extension lead will keep working whereas the old fuse would have blown.

## What are 3 amp fuses used for?

Different types of fuses Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example: 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.

## Can I put a 13a fuse in a 3a?

For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted. … BS1363 has standardised on just two preferred fuse ratings, 3A and 13A, however any fuse rating up to 13A can still be used.

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

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.

## 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.

## Can I use a 5 amp fuse instead of a 10 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.
