In daily electricity usage, many people have a misconception that unplugging sockets when not in use is safer and more energy-efficient. However, this approach is not applicable to all scenarios and may even cause damage to lighting electrical ready boards and related electrical appliances.

From a safety perspective, frequent plugging and unplugging of plugs can accelerate the wear of metal contacts inside the socket, leading to poor contact. When the socket has poor contact, the resistance increases, and high temperature may be generated when current passes through, which may cause fire or damage to electrical appliances. Especially for fixed electrical appliances connected to lighting electrical ready boards, such as refrigerators, air conditioners, etc., frequent power outages can also affect the lifespan of key components such as compressors, increasing the risk of failure.

In terms of power saving, many people mistakenly believe that inserting electrical appliances into sockets will continue to consume electricity. In fact, most modern appliances have standby energy-saving functions, and the standby power is usually extremely low (such as a TV with a standby power of about 1-5 watts). In contrast, frequent plugging and unplugging of plugs may cause the internal capacitors of the socket to consume more electricity due to instantaneous current surges, which may actually increase power consumption in the long run.

The correct approach should be handled in different scenarios: for appliances that have not been used for a long time (such as winter fans), the plug can be unplugged; For frequently used appliances such as routers and smart speakers, it is recommended to keep them powered on and control the power supply through the main switch or independent switch of the lighting electrical ready board. In addition, regular inspection of sockets and plugs for aging and looseness, and timely replacement of damaged accessories are the key to ensuring electrical safety.

In short, blindly unplugging is not a good strategy for electricity usage. Reasonably use the branch control function of the lighting electrical ready board, and choose whether to cut off power according to the frequency of electrical use, in order to balance safety and energy conservation.
