In the modern world, electrical appliances have become an essential part of our daily lives. Choosing and using these appliances properly not only helps to improve convenience but also saves energy and ensures safety for the family. This article will guide you on how to classify, use and preserve electrical appliances in the home, thereby providing the necessary criteria to choose the most suitable product. Let’s explore with QNT Investment and Trading Services Co., Ltd. to turn your home into a smarter and more efficient space!
I. Classification of electrical appliances in the home
1. Electrical wire
Currently, there are many types of electric cables on the market, such as 1 layer PVC coated, 2 layers PVC coated, 1 layer PVC and 1 layer XLPE, fireproof Mica layer, steel armored layer to prevent rodents, etc. So how to choose electric wires and cables that are suitable for each family’s needs?
With knowledge and experience in the field of supplying and installing electrical equipment, we advise you to choose electric cables as follows:
– If your house uses fireproof PVC conduit for electrical wiring, you only need to use a single wire (1 layer PVC coated) is enough
– If your house does not have the conditions to use PVC conduit, you should use 2 layers PVC coated or XLPE/PVC cable (people only use XLPE/PVC with large cross-section cables to increase heat resistance – increase the overload capacity of the wire).
– The power supply wire for the lamp is usually 1.5mm2 wire – the maximum current is 22A (4.8kVA – equivalent to 2 50L water heaters or 150 40W light bulbs). If the family wants to save, they can still run 1mm2 wire.
– The power supply wire for the socket is usually 2.5mm2 -29A (6.4kVA).
– The power supply wire for the entire apartment can use 6mm2 – 45A (9.9kVA).

2. Switches – Sockets
Here are some things to keep in mind when choosing switches and electrical outlets:
– Choose a 3-pin universal electrical outlet (if possible, grounding is even better for your home wiring system).
– Choose genuine products
– Note that the technician must connect the correct hot and cold pins when installing so that when the light switch is turned off, the phenomenon of dim lights and fluorescent lamps will no longer exist.

3. Lighting
There are countless types of lighting equipment on the market and each type of lighting is suitable for different spaces in the home, typically:
– Incandescent lamps
– In addition to the 40W – T10 type, there are also 28W – T8 or T5 types that are smaller but brighter
– LED lights – the most energy-saving and longest-lasting lighting equipment, however, the price of LED lights is higher than that of conventional lights. Therefore, families should choose reputable suppliers to avoid buying poor quality products.

II. Use and maintenance of electrical equipment in the home
1. Selection, use and maintenance of electrical sockets and plugs
How to choose sockets and plugs: Choose to buy sockets and plugs from famous brands and leading suppliers to ensure safety and efficiency when using. In addition, when choosing sockets and plugs, you need to choose compatible capacities to ensure normal operation.
Especially avoid buying thin plastic sockets, thin, loose copper contact plates, sloppy welding, etc., because these types are very quickly damaged and can easily cause fire and explosion.
How to use sockets and plugs: To ensure safety during use, sockets and plugs must be kept dry. Unplugging and plugging must also be done firmly to avoid sparks flying out, causing the risk of fire and explosion.
Along with that, before removing the socket, you need to remove the fuse or turn off the circuit breaker, use an electric tester to check again. If the pen does not show red, it means the socket has no power, in case both poles are red, the power is still on and the neutral wire is broken. When connecting the power cord to the two poles of the socket, use a tightly fitted core wire and handle good contact.
In addition, the location of the socket and the power switch should be located away from the water source, easy to observe and convenient to operate. The electrical panel and socket must be firmly fixed to the wall, and the electrical panel and socket must be well insulated.
How to preserve sockets and power plugs: When using sockets and power plugs, users should not leave the plug head loose, because doing so will easily generate sparks that cause short circuits and fires. Along with that, do not use open or cracked plugs. Do not place the power outlet near water or damp walls.
On the other hand, do not use many high-power devices in the same socket because it can easily cause a fire in the socket. Do not use water to extinguish the fire when you see the socket short circuit, but then calmly turn off the power circuit breaker.
Do not grab the cord of the power plug to pull it out of the socket, because doing so will easily break the wire and damage the plug head. The power cord into the socket and the plug must be checked regularly for damage to replace and should not use a cord with a plug into the socket.
2. How to choose, use and preserve power cords
How to choose power cords: When buying power cords, you need to pay attention to the usage needs. Therefore, when you need to buy power cords, users need to clearly identify the electricity needs of the family. The next step is to determine the parameters recorded on the power cord such as cross-section, copper core, number of copper wires, voltage, current, etc. Because if we choose a power cord with a current smaller than the load current, it will cause fire, short circuit, etc.
To check the quality of the power cord, users can check the quality of the cord by checking the copper wire inside (if the core of the cord is made of copper): Good quality copper wire is red-yellow, shiny and soft. On the contrary, poor quality copper wire is yellow-black and easily breaks when bent…
How to use electrical wires: When connecting electrical wires, they must be connected alternately and wrapped with insulating tape on the outside of the joints. Use specialized electrical conduit to thread electrical wires when wiring in walls or floors. In addition, when checking for electrical problems, for electrical wires threaded in walls, be careful if you drill the wall. If there are problems such as burnt electrical wires, short circuits… you must turn off the circuit breaker before handling them.
How to preserve electrical wires: As with using electrical sockets and plugs, there are special cases that should be avoided when using electrical wires. Accordingly, absolutely do not use electrical wires that carry electricity as clotheslines or hook them to other objects. Do not hook, hook or clamp electrical wires to another surface with rivets.
When using electrical equipment, absolutely do not pull or jerk the wire, causing the wire to break or damage the outer insulation of the wire… Along with that, do not use wall-punching tools such as metal chisels or drills to impact the hidden electrical wires.
Wishing you and your family the right choices and proper storage when choosing electrical equipment for your space!
