Proper use of power cords involves multiple aspects, including safe connection, avoiding damage, correct placement, preventing overload, and choosing the right power cord. Here are some key points:
Safe connection:
When connecting the power cord, make sure to connect the AC power correctly, especially when using three-phase electricity, pay attention to safe operation and avoid damaging the power cord1.
Avoid placing heavy objects on the power cord to avoid affecting normal connection or causing safety hazards1.
Avoid damage:
Do not only unplug the plug without unplugging the power cord itself to reduce wear and tear on the power cord to avoid safety hazards1.
Avoid touching the power cord or plug just after washing your hands, as moisture may cause electric shock1.
Proper placement:
Replace old or damaged sockets in time, especially when the socket shell is cracked, the copper wire of the power cord is exposed, the socket has poor contact or turns black, or melts and deforms, it should be replaced immediately2.
Do not use the socket on ordinary ground to avoid dust from entering and causing short circuits. At the same time, do not place the socket near flammable materials such as sofas and bedside tables, and ensure that children cannot reach it2.
Prevent overload:
Check the power of the appliance before use, and avoid using two appliances with a power of more than 1,000 watts on the same power strip to prevent overload risks
