1. Correct selection
Choose appropriate wall switches and sockets based on the total capacity of the electrical appliances and the specific usage environment. In places with high humidity, fireproof wall switches and pull-cord wall switches should be used; wall switches and sockets should not be installed indoors with corrosive substances or high dust levels, but should be installed outdoors; in places with fire or explosion hazards, fireproof or explosion-proof wall switches and sockets should be used.
2. Correctly select rated current and rated voltage
The rated current and rated voltage of wall switches and sockets must match the technical parameters of the electrical appliances. Overloading is strictly prohibited to prevent overload from burning out the insulation, causing a short circuit, and potentially leading to a fire.
3. Select the correct fuse
Knife wall switches must use matching fuses. Arbitrary alterations are not permitted, especially thickening of the fuse element, and the use of copper, aluminum, iron, or other metal wires as substitutes for the fuse is strictly prohibited.
4. Single-pole wall switches should be installed on the phase line.
A single-pole wall switch should control the live wire, not the neutral wire. Otherwise, even if the wall switch is off, contact with either the live wire or the neutral wire can still cause an electric shock. If the live wire is grounded, a short circuit or even a fire may occur.
High-power appliances should be connected to a separate power supply.
Avoid using light sockets.
Because high-power appliances (microwave ovens, induction cookers, electric stoves, air conditioners, etc.) draw a large current when operating, dedicated sockets should be used to power these appliances, with a rated current of not less than 10A. The connecting wires should ideally be drawn from the main electrical distribution box. Use aluminum core wire with a cross-sectional area of not less than 2.5mm²; or use copper core wire with a cross-sectional area of not less than 1.5mm². Avoid operating high-power appliances simultaneously. Never use lamp sockets with high-power appliances, as this can cause a fire due to severe overload.
6. Repair damaged electrical appliances promptly and replace aging wires as soon as possible.
Wall switches and electrical outlets should be repaired or replaced promptly when they are old or damaged to avoid fires caused by improper use.
7. Disconnect the power supply immediately.
When going out, sleeping, or during a sudden power outage, be sure to turn off the power immediately, especially for electric heating appliances.
8. The installation environment is important.
Wall switches and sockets should be installed in dry, clean, and dust-free locations to prevent moisture and corrosion from causing insulation breakdown, short circuits, and fires.
9. Minimize the use of multi-outlet sockets
In rural areas, many families habitually plug multiple appliances into the same multi-socket, and these appliances are often used simultaneously. While this seems convenient, it actually has many drawbacks. Because multi-sockets and power cords have rated capacities, using multiple appliances simultaneously on the same socket inevitably leads to excessive current, causing voltage drops and affecting the normal operation of the appliances. If the voltage drop is too large, it can damage the appliances and cause the wiring to overheat and burn out due to overload, potentially even causing a fire. Furthermore, too many sockets can lead to improper spacing and insufficient precision, potentially causing electric shock accidents. Therefore, frequently used appliances in fixed locations should be plugged into their own dedicated sockets.
10 plugs should be wiped clean regularly.
Electrical plugs should be wiped clean frequently; otherwise, dust or oxides will gradually accumulate on the two poles of the plug, increasing the contact resistance between the socket and the plug, which will affect the service life of the socket or burn it out, and may even cause a fire.
