Today, we will introduce the process of installing waterproof socket on the wall outside the house in Japan. First of all, we should recognize a question: is the waterproof socket really waterproof? Yes, it's waterproof. But it's not completely waterproof. First of all, the designer's original intention is that when the socket is exposed to the outside, there is no problem in the degree of being drenched by rain, but it is not OK to soak in water or pour water from the bottom to the top on the socket. So, even if it's raining, you can use the socket normally. I'm afraid your electrical equipment is not waterproof.

The cassette used for socket is pre embedded, the inside of the cassette is very clean, there is no cement in it, and there is no gap with the surrounding, which is very flat. The position of the upper screw is also intact, and the wires are well threaded. Hey, speaking of wires, there are two different kinds of wires in the picture above. Do you know why? If you know the reason, you can leave a message at the bottom of the article and let me know. The job manager will announce the answer in the message box at the appropriate time.

This picture is just on the opposite side of the wall. It was taken during the period of embedding. The pipe will be fixed on the steel bar with iron wire after it

One on the side, prepare to install waterproof socket after stripping the wire.

First of all, fix the white base of the socket on the cassette. The base is made of hard plastic. The screws used outdoors must be stainless steel. We all know this. The cassette is also made of resin and will not rust. According to the requirements, insert the 100V power cord into the back of the socket. In the previous article, the head of the secondary vocational school repeatedly introduced the length of the copper wire exposed when peeling. In Japan, 12mm is the standard, and the so-called standard is that it will be completely stuck and will not be long when it is inserted.

If the copper wire is exposed after the power cord is inserted, it is unqualified in Japan. Is copper wire exposed on the back of the switch and socket panel in your home? If everyone is serious, the insulation value is not good, poor contact, including leakage, electric shock accidents will be reduced a lot.

The gray panel on the left is made of soft rubber, which is marked with what wires can be inserted, how long the wires should be peeled, and the positions of positive and negative poles and ground wires. The left screw is fixed on the right base. After the screw is tightened, the rubber will stick tightly to the wall to achieve the function of waterproof. If the water seeps in, the water drops can be discharged to the lowest outlet through the surrounding sink (see the penultimate picture)

It's like the front when the upper screw is tightened. The Japanese consciousness of the surface print is: (1) screw the plug to the right after inserting; (2) turn left when removing the plug. Also, the awareness of the figure below the panel should be that there are two sockets that can be used, and then the direction. The grounding part of the plug is on the right side. When inserting it, it won't fall down if it is twisted to the right, and it can't be pulled out by hand. It's anti falling design.

The one in the lower right corner is for grounding wire. You can see the drain hole just mentioned below. The wall is the original appearance, and then it will be ground flat, and applied with waterproof glue and paint. When painting, workers will wrap our waterproof socket tightly. In Japan, I'm very relieved about that.

In other positions, electricians installed the water plug at the designated position (we installed it first) when they embedded it according to their own drawings, and the water plug was also placed at the designated position according to their own drawings. The communication between supervisors was not in place. There is a water source beside the socket. I don't know how to deal with it in the final acceptance.
