When decorating a house, the safety issues related to sockets cannot be ignored. Generally, five-hole sockets are often used in daily life. The installation of this is relatively simple. The main problem is wiring. , if the wires are connected correctly, there won’t be much of a problem. So how do you connect the five-hole socket? You must not ignore this problem, so I will help friends who need help to solve this problem.
1. Wiring method of five-hole socket
1. After arranging the conduit and wiring, we can start to install the five-hole socket. Friends who are familiar with the five-hole socket know that there are three terminals on the back of the five-hole socket, which are marked L, N, and E (marked by PE or (painted earth symbol)). The line marked L is the live wire, and the line marked N is the zero line. wire, the wire marked E (PE or earth symbol) is the ground wire.
2. When wiring, connect the fire cable (yellow, green or red) to the L terminal of the five-hole socket, connect the neutral wire blue to the N terminal, and connect the yellow and green wires to ground.
3. When wiring, please pay attention to the following issues: when stripping, do not strip too much to avoid too much copper wire, which is unsafe; insert the wire into the terminal until the end; tighten the terminal screw to prevent the terminal from loosening .
2. Understand the internal structure of the five-hole socket
1. There are three exposed holes in the five-hole socket wiring, which are L-type, N-type and E-type grounding. In terms of aspects, usually the cold wire is the neutral wire, the warm color is the hot wire, and the middle color is the ground wire, but it is not static. Cool colors are green, blue and black, warm colors are red, orange and yellow, and intermediate colors are gray, purple and white. You may remember that the hue formula of a section of cable is: ABC, the phase is yellow, green and red, the neutral wire is light blue, the two-color ground wire of yellow and green, the internal wiring is black; the DC cable has two poles, the color of Chu is The positive pole and the negative pole are blue.
2. For enhanced safety, you can use a pen to identify the line of fire. Usually, the neutral wire is on the left and the live wire is on the right. Wiring a five-prong socket is much simpler by remembering the following principles and methods. Flame red and black blue earth, the live line L is red, the neutral line N is black, the landing line is blue, the fire brown zero blue earth is yellow-green, that is, the live line L is brown, the neutral line N is blue, multi-color The yellow-green wire is the ground wire, fire black, zero white ground, green is the standard for American wire, based on the path usually only inside and outside the phase wire, you can only think of the live wire and neutral wire, it is usually used to match the target yellow, The wires have a green tone and the switch is usually labeled Input Phase L and Phase L1L2. If you find two wires of the same color, that's good, otherwise something in the circuit will be broken.
3. Five-hole socket wiring precautions
1. How to confirm the live wire of the internal circuit and the five-hole switch socket: As long as the circuit is energized, the live wire can be charged regardless of the switch. . If you are unsure of the color, you can use a pencil test. The key to using the test pencil correctly is to wear: insulated shoes. Place one hand behind your back and the index finger of the other hand on the metal cap at the end of the test pen. Hold the insulation layer of the pen body with your thumb and middle finger. Do not grab the metal rod. When testing the power supply, please be careful not to connect the ground wire.
2. When installing a single-phase two-hole socket, if the hole on the socket is placed horizontally, it must be "zero to the left, fire to the right". If the hole of the socket is placed vertically, it must be "fire, fire, to the right". Drop to zero". The three-hole socket must be "zero on the left, fire on the right", with the protective ground wire at the upper end, the neutral wire and the protective ground wire must not be connected incorrectly, and the neutral wire and the protective ground wire must not be connected to each other. Seats must be checked based on the color of the cables.
3. Generally, the five-hole plug installed on the surface should be no less than 1.8m from the ground, and the hidden power plug should be 0.3m away from the ground. To prevent children from coming into contact with each other, it is best to choose safety plugs with safety deflectors. Plugs in the same room must be at the same height, and switches must have the same on and off positions.
4. What is the brand of the five-hole socket?
1. The connection of the five-hole socket has a certain relationship with the quality of the five-hole socket. Due to the reasonable internal structure and regular parts, the high-quality five-hole socket is convenient and easy to connect.
However, some inferior products have more complicated wiring. Let’s take a look at the brands of higher quality five-hole sockets.
2. In the current market, five-hole sockets are relatively well-known brands, such as Simon, Legrand and Siemens. Highly recognized, Simon is a more classic fashion product that uses new materials, high-level technology, and has considerable influence on the industry; flash switch plug products have many patents in the industry and are in the industry has always been in the leading position. Of course, in addition to these, there are many high-quality five-hole plug brands, such as Qisheng, Meilan Erlan, Feidiao, Hongyan, Huntkey and other brands. These brands are national brands, cost-effective and suitable for most working class people.
The above is about the five-hole socket wiring. I believe that by learning the wiring method, it will be much easier in actual operation. You must be careful and pay attention to safety. Only when the five-hole socket wiring is paired, can the There will be no security issues.
