Understanding House Fuses
So every house has a house fuse, and they are the very essential components of an electrical system. They are designed to safeguard against potential hazards. These are the protected devices that are installed in every house and act as a barrier to regulate the flow of electrical current. They have a metal wire that is in a protective case. The main function of this is to safeguard by breaking all the circuit if any fault happens in any appliance by the flow of too much current by overloading, and protecting the wire and appliances. This type of fuse is also very helpful in reducing the risk of fire damage and any dangerous incidents that can happen due to an electrical shock.
Types of fuses
If you have ever noticed an electrician putting a fuse in your house, you must have found that there is just not one fuse in the whole house. There are several types of use that are actually commonly used in the household.
Cartridge fuses
This is the fuse, which has a cylindrical body and is available in different sizes. When the current exceeds the rated capacity or there is any overloading of the fuse, the fuse element will melt and break the circuit to protect the house’s system. It is commonly designed to be used in circuits that have a high current rating or high voltage rating and have been commonly used in very old homes.
Circuit breakers
Even though cartridge fuses are so conventional, the circuit breaker is the switch that opens on its own whenever it senses an electrical problem. These are also intended to guard against damage from overloading or any kind of home short circuit. Although they are essentially just any kind of fuse, because they can be reset after the trip, they are thought to be more convenient than other fuses.
Blade fuses
These are the fuses that are used for home applications with low voltage uses and are primarily found in automobiles.
Glass tube fuses
Another type of use that is used for low-voltage circuits is a glass fuse, which has a glass body and is actually filled with sand or any other material that acts as an insulator.
Ceramic fuses
This fuse, like glass tube fuses, is filled with sand and other insulating materials. It has a ceramic body and is commonly used for high voltage circuits.
Common electrical issues
Circuit breaker tripping
Circuit-breaking tripping is one of the most common electrical problems among all households. A rare tripping or circuit breaking problem is normal, but if any circuit breaker breaks periodically, it could indicate a more serious issue in the household requiring professional attention. This can be caused by overloading the circuit, a short circuit electrical fault, or any worn circuit breakers.
No GFCI outlets
GFCI outlet stands for ground fault circuit interrupters, which are critical when an outlet is exposed to water. This GFCI outlet will detect a fault in a very short period of time and help to drive its internal breaker, potentially saving your life. GSA outlets are extremely important for any household and are required in any location where a water connection is available, such as in a bathroom.
Aluminium wiring
If you have aluminium wiring in your home, it is strongly advised to replace it with copper wiring, which is fire resistant.
Dysfunctional switches
In many households still in India, switches are one of the electrical components that are taken lightly when it comes to safety. Even if the switch is lost or cracked over time, it can cause malfunctioning and lead to the strobbing of lights.
Flickering of lights
Light flickering is a common occurrence that can be caused by lost wiring or an issue with the electrical service. This typically occurs on windy days, but this situation should not be taken lightly.
If we talk about the consequences that can cause by the electrical hazard, this includes burn electrocution, arc flash, electric shock, and can be can cause other serious in injuries in the extreme cases, it can even lead to the fire explosions and can threaten to life, property, and overall safety of the environment and oneself. Not only that, there are several risks associated with electrical issues even for any electrician if he or she has inadequate training and lack of experience. According to the report given by the Council on Energy, Environment, and Water over the last ten years, the Government of India has been constantly trying to provide electricity privileges to every part of the society in India.
Choosing the right fuses
How to match the fuse to the electrical board? To match the fuse to the electrical load, you need to find the suitable current rating for a fuse, considering the load current and a safety factor. The fuse rating equation is given as follows:
Fuse Rating (If) = Load Current (Il) x Safety Factor (SF)
Where:
- If is the fuse rating in amperes
- Il is the load current in amperes
- SF is the safety factor
The fuse rating equation helps to determine the appropriate fuse size for a specific circuit.
How to understand fuse rating and sizes? Fuse ratings are critical criteria which define the current carrying power of a fuse. They are expressed in amperes (A) and symbolise the maximum current that the fuse is capable of handling without cutting the circuit. When unsure about the correct fuse ratings and sizes, look for assistance from an electrician. They can assess the electrical system’s particular demands and advise on how to choose the appropriate fuses.
Installing and replacing house fuses
The first step in replacing a fuse is to turn off the power, which ensures your safety by preventing you from receiving an electric shock during the process. To proceed, you should be familiar with the fuse’s correct circuit and wiring. You can opt for any professional help or try to match the rating of the fuse by yourself by inspecting for damage and defects before installation or upgrading. It is very crucial to inspect the replacement fuse for any kind of physical damage, such as cracks. A burned or used fuse should never be used, as it can disrupt the circuitry of the house. Connect the fuse to the socket. Now you can turn on the power gradually and verify the whole circuit by consulting an electrician. The whole process is very complex and challenging, so it is advisable to seek professional help.
Signs of electrical issues
Here are some warning signs to not ignore, if you have any:
- Heating generated from electrical appliances
