Before using electrical appliances such as heaters and air conditioners, residents should pay attention to the wattage labeled on the appliances, and compare these values with the current labeled on their own energy meters. If the former value is greater than the latter, high temperature wires may be damaged, which is dangerous.

   In addition, you should also pay attention to some details when using electrical appliances. For example, the wires of electrical appliances should not be pressed by heavy objects; the plugs of electrical appliances should be wiped frequently; fuses in the house should never be replaced by copper wire or other high melting point metal wires; batteries that cannot be recharged should not be brought in to charge, otherwise they may explode; when plugging or unplugging the plug, you should focus on the plug and do not pull the wire tightly.
  Residents are advised not to use more than one high-powered household appliance at the same time, and should apply for additional high-temperature cables if the meter capacity at home is insufficient. Residents should replace aging wires in a timely manner, and if they find smoke or smell a strange odor, they should quickly cut off the power supply at home to avoid a fire.
