Fuses in Electrical Appliances | Cap1sucks Home Improvement

One aspect of the electrical equipment that tends to cause much confusion is the question What fuse should have this tool? In this paper, we examine the fuse in detail and provide guidance on how to work the correct fuse for the device.

The fuse?

Fuse is an electrical component which is designed to prevent the flow of a higher current than the fuse. For example 3A fuses will explode if the current flowing through it exceeds 3A. Fuses used in circuits to prevent excessive current flow in a damaged and cause a fire. All electrical plugs used in the UK with a fuse 3A, 5A or 13A. The main purpose of the fuse is to protect the power cord and prevents the fusion and / or catches fire in a damaged condition. The fuse that is used is based on the strength of the tool. Some very powerful tools, such as electric heaters will be more common and most often will require a 13A fuse with the cable that can carry the current level. The fuses are color coded for easy identification as shown below.

3A ? Red
5A ? Black
13A ? Brown

Fuses on the power plug is formed

Such as spark plugs are molded into the fuse on this wire can be repaired by the manufacturer. They know what the maximum current carrying son and fuses can be selected to protect the cable and blow if the flow exceeds the capacity of the cable. The value of the fuse is installed in the molded plug is marked on the outside. This makes the job of checking the fuse in the plug is formed very easily. Only on the lever the fuse and check that the value is equal to that indicated on the form.

Fuses on the power plug removable

This is where users can connect over. These plugs can withstand currents up to 13A and identified as such. Many people assume that this means 13A fuse must be used in this tool is a mistake. Fuses in the power rewiring sometimes marked on the paper label affixed to the sheet, or mentioned in the user manual. But in many cases, people who check the tool to work on the value of the correct fuse. We must first understand that the energy consumption of the device. It is generally expressed in watts on the label.

For example 1

The iron is equipped with a fuse 13A and the energy consumption of the device is 1900W. Since this is greater than 700W, this is the right fuse for the device. If the cord of this iron is changing, it is important to replace it with the same type, capable of carrying 13.

Example 2

Advice on the label of this light that the maximum that can be mounted lamp is a 40W. The cap is equipped with a fuse 13A. As the power is very low, we can quickly see that the fuse is too high and should be transformed into a 3A.

Example 3

This toaster has a plug provided with a fuse 13A and depending on the wafer has a power 700W. Since it is only on the decision point, what should we do? In general, heating equipment is equipped with a 13A fuse. If in doubt, check the cable that is used to sandwich toaster. If able to take the fuse 13A and 13A is the right choice.

What is the relationship between watts and the fuse?

This is a simple calculation to determine that. Simply divide the power (in watts) 230V (line voltage in the UK) to work on the current (in amps) taken by a tool. In example 1 above, it will 1900W/230V gives our current 8.3A. One can see that 3A or 5A fuse will blow if used continuously in a plug of iron leads us to choose a fuse 13A. Thus we arrive at the threshold of our decision 700W. A tool with a power consumption of 700W power consumption of 700W/230V 3A. Below, we can use a 3A fuse and above this we are using a 13A.

Example 4

A travel kettle for use throughout the world on either 110V or 230V has a 13A fuse installed and evaluated at 600W. Cable that is used to take the 13A and the kettle has a switch to select 110V or 230V operation. Should I replace the fuse to 3A, because this is below our threshold of 700W? If we use the above calculation, we can see that the current consumed by the boiler is only 2.6A (600W/230V). Thus, the 3A fuse should be accepted. However, when the boiler is used, for example in the U.S., the switch will be set to the 110V position. When the kettle is in use, it will take 5.5A (600W/110V). Thus, the 3A fuse keeps blowing. In the journey of the boiler because it is designed to be used and was equipped with cable 230V/110V 13A, 13A fuse is used the right choice.

Example 5:

This exercise has the power of 570W, but with a 5A fuse. Our calculations using the draw being only 2.5 (570W/230V). Why not fitted with a 3A fuse? Some equipment, such as taking exercise surge when turned on, which may exceed the normal operating current, is 2.5. If a 3A fuse is installed, people will find that this will blow often operate. In this regard, the 5A fuse fitted is the right choice. Remember: If the fuse is a 3A or 5A installed not change it.

Fuse label

Once the form has been checked for the correct value of the fuse, it is good practice to close the plug. If in the future proofing seal is still intact, then it is a good indication that nothing is altered or modified wire.

How can you tell if the cable can take the 13?

Cable size is indicative of the current carrying capacity. So the best way to check the value right now is to check the cable diameter. If the cable outer diameter is about 7.5 mm or more, then it is likely to be rated at least 13A. Each driver also has 40 in her son.
