How to use extension cords with splitters correctly to ensure safety?

1. Choose high-quality extension cords with splitters
First of all, it is crucial to choose high-quality extension cord with splitters. High-quality extension cords usually use high-specification wire materials, such as copper core cables, which have better conductivity and durability. In addition, the socket design of the splitter should have good plug-in properties to ensure that each socket can maintain a stable current supply when connecting devices.

Product safety certification is also the key to purchase. It is necessary to ensure that the extension cord has passed relevant certification standards such as CCC and CE to ensure that it meets electrical safety requirements.

2. Ensure that the load of electrical appliances is within the rated range
When using an extension cord with a splitter, it is important to note that the total power of the connected electrical appliances does not exceed the rated power of the extension cord. This is because the current carrying capacity of each extension cord is limited, and using it beyond the rated power will cause the wire to overheat and cause a fire. Usually, the power load will be indicated on the package or instruction manual of the extension cord, so it should be carefully checked before use.

3. Reasonable layout to avoid wire tangling and squeezing
When installing an extension cord with a splitter, the position of the extension cord should be reasonably arranged to avoid bending, tangling or being squeezed by heavy objects. Excessive bending and compression will damage the insulation layer of the wire, resulting in the risk of short circuit or leakage. The extension cord should be laid in a safe and ventilated place, as far away from flammable materials as possible, and avoid excessive stretching or keeping the wire in a tight state.

For extension cords with splitters used outdoors, special attention should be paid to their waterproofness. Choosing products with IP44 protection level or higher can effectively prevent rain or moisture from entering the extension cord socket and avoid leakage.

4. Check the condition of the extension cord regularly
After long-term use, the extension cord may be damaged due to aging or frequent plugging and unplugging. Therefore, regularly checking the condition of the extension cord is an important step to ensure safety. The following points should be noted during the inspection:

Whether the wire has signs of damage or wear;
Whether the plug and socket are loose or burnt;
Whether the splitter has heat or odor.
If any damage is found on the extension cord, stop using it immediately and replace it with a new one in time. Do not attempt to repair it yourself or temporarily connect it to avoid accidents.

5. Avoid long-term high-load operation of the extension cord
Even if the rated power of the extension cord meets the use requirements, it may cause overheating problems if it is in full load for a long time. Therefore, it is recommended to avoid long-term high-load operation of the extension cord and cut off the power supply in time. For electrical equipment that is not in use, unplugging it in time can effectively save electricity and reduce the load of the extension cord.
