1. Prepare the socket to be installed and the cable. For example, in the figure of "two sockets", three three color connectors are required. The "three" and "four" are the same.

2. Insert the "red" or "yellow" cable into the L hole; insert the "green" or "blue" cable into the N hole and insert the "flower" or "two-color" into the ground hole. Note: L refers to the fire line and N refers to the zero line.

3. After completion, as shown in the figure. Note: It is the norm and standard to distinguish the fire, neutral, or ground by color, but it is not dead. The only thing to note is that the L, N, and ground lines must correspond one-to-one.

4, Figure 1 is the three-line three-color one-to-one correspondence, clear and intuitive, normative. In Fig. 2, there is a 4-position socket, a nine-line three-color one-to-one correspondence. This way, you can ensure that each outlet is connected.

5. Next, insert the incoming line (coming line) into the L, N, and ground holes by color.

6. Finally, tighten the screws of “Every One Hole” with a screwdriver until the wires cannot be pulled out.

7. Next, secure the socket to the dark box with the M4 screw.
