In the use of electricity, theoretically, the thickness of the wire has a certain impact on the safety of use, but people often ignore the use of insulating tape at the wire interface. Today's power paths are becoming more and more complex, with use under floors, in walls, in partitions, and in dark, damp basements or in impure water. Insulating tape is not used correctly, and great danger can occur.
We know that the power cord connector is divided into "+" word connection, "-" word connection, "T" word connection and so on. No matter what the method should be the first joint should be wound, smooth and no burrs, before the thread is pinched and broken, it should be pressed with pliers, and then around the pressure mouth, and finally shaken, the thread is easily broken. In a dry environment, you should first wrap two circles with insulating tape, then wrap two circles of plastic tape, and then use insulating self-adhesive tape to stretch up about 200 percent, wrap two to three circles, and finally wrap two circles of plastic tape, which is safer.
