Nowadays, electricity is an indispensable part of our lives. While it brings us convenience, it also poses certain safety hazards. Plugs are a crucial component of our daily lives. What should we be aware of when using them?
Avoid inserting or removing plugs with wet hands, as water is conductive and could lead to electric shock incidents.
2. Avoid yanking the power cord by hand when plugging or unplugging it. Some people, to prevent electric shocks, are very cautious during the process. Instead of holding the plug, they pull the power cord directly, exerting force. After doing this repeatedly, the connection between the cord and the plug can be pulled apart, rendering the appliance unable to supply power properly. The broken section is prone to short circuits and leaks, which can lead to fires and electric shocks.
3. Discover abnormal electrical outlets or plugs and replace them promptly. When you notice excessive heat from the outlet, arcing, sparking, poor contact between the plug and outlet, or if the plug is too loose or too tight, immediately cease use and replace it.
4. Avoid using outdated outlets beyond their lifespan. Outlets also have their own service life. If you frequently encounter loose connections and poor contact when plugging in, it indicates insufficient spring tension inside, signifying the outlet has reached its retirement age. Additionally, when outlets are used past their due date, the internal copper components may age, and the casing's insulation may degrade, leading to potential issues such as the casing becoming electrified and poor contact during use, which can harm both the user's personal safety and the safety of the appliance.
5. Avoid "a small horse pulling a big cart." An outlet has a primary specification: rated current. The rated current of the appliance plugged into the outlet should not exceed the outlet's rated current; otherwise, using a small horse to pull a big cart, the outlet may overheat, affecting its lifespan, damaging the appliance, or even causing a fire. Pay special attention not to plug in high-power household appliances like air conditioners and microwaves into outlets with a lower rated current.
Ensure plug prongs are regularly cleaned. Neglecting to do so can lead to the gradual accumulation of dust or copper corrosion at the plug's terminals, increasing the contact resistance between the outlet and plug. This can cause overheating when in use, which may affect the lifespan of the outlet, damage it, or even lead to a fire.
7. Avoid altering plug sizes and shapes. Many homeowners, upon purchasing an appliance, may find that the plug doesn't match their home's outlet. Instead of replacing the outlet, they opt to modify the appliance's plug size or shape. A common practice is to break off the grounding pin of a three-prong plug and use it in a two-hole outlet.
