Three-hole plug how to divide the zero wire fire wire ground wire

Generally speaking, the zero wire is on the left, the fire wire is on the right, and the center is the ground wire. The voltage between the zero wire and the fire wire is not the same, so be careful when wiring, if the operation is wrong, then it will give the use of up to bring trouble, and serious will also cause safety hazards.

Three-hole plug selection:

1, consider the distance between the two holes and three holes

Now on the market is basically a five-hole socket design, the use of this hole in the socket is often required to use the converter, if the plug is more specific, then it can only be a plug to use. Therefore, in the purchase of the time, due to pay attention to the distance between the two holes three holes, the larger the hole distance represents the more convenient to use.

2, consider the issue of security

Safety is one of the most important factors in the purchase of sockets, we are buying, we must be in accordance with the national standard regulations, each socket is more than equipped with a safety gate. Socket is not in use, and the air before is clamped with a piece of plastic, which can prevent electrocution accidents, only when the socket is inserted into the inside, the safety door will be opened.

3, consider the socket component material

Buy socket, but also need to pay attention to the material of its components, and copper is one of the most important components. Good copper flexibility and conductive function are very good, and the use of a long time is not easy to appear rust phenomenon, the humid environment will not have any effect on it.
