6 things you should know about electrical short circuits

The word short circuit is a word that everyone has heard. Because when there are reports of fires in various places, short circuits are always brought to the fore. Which if an electric short circuit occurs when it creates a risk for various dangers Can come up so much Therefore, in this article, we will get into the house electricity power. Cause of short circuit Including how to prevent And fixes no short circuit problems

1. What does the electricity in the house look like?
Electricity in use today can be divided into two types: direct current. slotxo And alternating current Which the electricity used within the house will be an AC type With a voltage of 220 volts, the electrical circuit connection in the house will be connected in parallel by power supply through 2 wires (excluding grounding), which is the advantage of parallel connection when some home appliances. Have a problem Other appliances Still able to continue to use Because they are not in the same electrical circuit
The schematic for the electrical circuit for use in the house can be explained easily. There is an electric wire from the electric pole to the electrical control box in the house By the electrical control box that controls all electrical systems in the house. Inside the electrical control box will separate wires to different points. According to the needs of the residents there

2. What causes a short circuit?
A short circuit is caused by the contact of two different voltage points. Or there is a thing that conducts electricity between the two points, causing a short circuit. When these two points touch each other, the current will be faulty. This is because a large amount of electric current will be transferred together to generate high heat. And a spark came up
In summary, a short circuit is caused by the two wires running inside the house that come into contact with each other without insulation. This may happen for several reasons. Or there is some object that conducts electricity in the area and connects the electric current from the two wires in direct contact. When it comes into direct contact, it creates a short circuit which becomes so hot that a spark can occur. And that spark will stick to the materials Until eventually causing a large fire

3. Is the power cord damaged causing a short circuit?
It is a question that the only answer is. When the power lines that run inside the house are damaged The malfunction of the electrical wiring in the house can occur for many reasons. No matter how old the wires cause the insulation to decay and not in perfect condition. The presence of various animals For example, rats gnaw the wires until the insulation that was covering the wires was torn. Including the fire in the wrong way that the wires can move back and forth, causing frequent friction. That causes the insulation to cover the wires to be torn
Therefore, it can be concluded that a malfunction of the power cord will definitely cause a short circuit in the house. Just wait for the time when that problem will arise.

The power cord is damaged. 4. Other causes of short circuit.
In addition to a damaged electrical cable, it is the cause of a short circuit. There are other reasons. That can cause short circuit problems as well Which of those reasons include

Defective electrical appliances Electrical appliances in the house must be constantly checked that it can still work normally or not. Is there a condition available or not? If any electrical appliance is too old. Or not working normally, may be in the power cord within that appliance Have damage Or internal circuit is damaged Which is one of the reasons that can cause a short circuit
Incorrect use of the power strip Of course, every home cannot have a power outlet installed at every point where an electrical appliance is installed. Different types of extension plugs It is a matter that cannot be avoided. The use of power strips that will cause a short circuit is to use non-standard power strips. Including plugging in large electrical appliances that consume a lot of power Into a single plug This will cause the plug to work too hard and cause a short circuit.
The power cord is not standard. Each house will have different power input according to user needs. Which nowadays, almost every home has asked for electricity to increase the amount of electricity into the house almost 15-30 Amp. Because there are more appliances in the house Causing more electricity to be used
But adding electricity to the house, not just having extra electricity, will be done. Electric current Including the quantity of electrical appliances that is more recommended that you need to check the wiring. And the electrical control cabinet within the house that is capable of enough to handle the electricity. And the use of electricity added or not as well Which is a matter that an expert technician should come to inspect

5. How to prevent short circuit
When knowing the causes That caused a short circuit Let's take a look at how to prevent a short circuit from occurring.

Old power cord, damaged power cord, do not use. If it is found that the electrical wiring in the house is so old that it is likely to be dangerous. Or there is a damage that can be seen clearly, stop using the lights in that area immediately. And called a skilled technician to change the new power cord as quickly as possible
The size of the wires must be standardized. As I said, today's homes have electricity consumption. And more electrical appliances If it is a new home, problems with the standard of the appropriate electrical wiring are seldom used. But if it is an old house that has been built for a long time, the wires The house will last a long time. And it is also an older power cable that can handle less current than the actual use today.
Always check various electrical appliances. A damaged interior is another common cause of electrical short circuits. Therefore, keeping in mind that electrical appliances can still work normally or not. Or if found to be damaged, must stop using immediately This will greatly reduce the risk of electric short circuit in the house.
Choose a quality power strip. Choosing a quality power strip can help prevent short circuits. Because the quality plug has its own internal power cut. If found to have electric shock Or has been using more than the specified amount of current The power plug will be turned off immediately. This makes choosing a quality extension plug that is very important to use.
The electrical system in the whole new home. When their own homes have more requests for electricity And there are a number of various electrical appliances Even more, to find a specialist to check the standard of the power cable. And that the home electrical control cabinet is standard enough to support all functions or not. If the old wiring is not up to that standard, all the electrical wiring in the house must be replaced immediately. Including changing various circuit breakers In the electrical control box to be standard as well
But nowadays, requesting to use a larger amount of home electricity from the electricity utilities must strictly follow the regulations of the Electricity Authority. The electrical authorities will have a manual that if additional electricity is requested, the home electrical system must be improved. Including various circuit breakers What is in the electric control box? Then there will be an official to be sent to inspect If this cannot be done according to the standards of the Electricity Authority, there is absolutely no permission to increase the amount of electricity.

6. What should I do when there is a fire from a short circuit?
If the electric shock occurs until a fire has already occurred The first thing that should be done is to cut all functionality of the home lighting system. By letting go to chop off the big breaker that is used to control the incoming and outgoing power within the house Then, use a volatile liquid fire extinguisher to spray to extinguish the fire. Due to this type of extinguishers, the extinguishing agent will evaporate into the air. Do not damage electrical appliances
As for the prohibition when the fire occurs from a short circuit, it is strictly prohibited to use water for extinguishing the fire if the fire has not been cut in the area because water is a conductive of electricity. Using fire water not only damages electrical appliances, but also puts people who splash water at risk of electric shock. As for the use of dry chemical fire extinguishers, although it can be used to extinguish the fire effectively. But it can also damage electrical appliances.
But if it is estimated that the fire that is burning cannot be dealt with by itself Immediately notify the fireman As well as immediately move all the residents of the house The short circuit problem is a big problem that cannot be overlooked. Because if there is a clear electric circuit that becomes the cause of the fire, it will result in enormous loss of life and property, so being careful not to cause electric short circuits is important. And always have to find knowledge on how to prevent the most effective
