distribution box can be described as a piece of cake. But for plumbers without professional knowledge, how to wire the distribution box is a difficult problem. Many people have been working in plumbers and electricity for many years, let alone connecting the distribution box, they may not even fully understand the circuit. Many people say that water and electricity installation is simple, but after actually doing this industry, I realized that this is an industry that can keep getting old and learn! Many people have asked me before about wiring the distribution box. How to connect the distribution box? To be honest, some questions are really not something that can be explained clearly to everyone in a few words. Now I will share it with you in the form of graphic tutorials. Since the work does not focus on any craftsmanship, there may be some things that are not done well. Everyone is welcome to criticize and guide them.
Text starts:
The electric box that has just been put through the line is usually quite messy, but don’t forget to mark each set of lines, because the box cover will have to be marked in the future. If you connect it wrongly now, the logo will also be wrong in the future.
For example: Which group belongs to the kitchen and which group belongs to the bathroom, these must not be messed up. If it is messed up, then each set of wires of each electric box needs to be distinguished again in the future. If you encounter a project, a lot of labor will often be wasted on these details.
will share with you a small experience, that is, when threading, mark the outlet of each set of wires, so that it will be easier to remember. For example, use letters or something instead!
When sorting out the electric box, the first thing is to do is to sort out the lines and figure out where each set of lines is connected, especially those circuits where the neutral line only enters zero and does not open in the empty space. It is particularly necessary to distinguish them. Don’t tie them all up and bend them at that time. When you look back, you will find that the connection is wrong and then disassemble and re-tickle them. This will be troublesome!
The electric box was a bit unsightly before it started to be sorted out. Let’s look at the final finished product!
wires should be tied into bundles and then tied into bundles of corners, so that the bent corners will look much better! If you say that the corners of the electric box are bent one by one, it will appear even more inconsistent, especially the soft wires used! When binding the
wire, if there is obsessive-compulsive disorder for the wiring, then it depends on which wires are tied above and below. When the connection is opened, it will not cross, and it will look much better. After the
wire is tied, don’t rush to install the empty space. Connect the wires that need to be connected to the neutral and ground wires first. If you install the empty opening first, the space in the box will become very narrow and the operating space will be small, so it will definitely be difficult to do wiring.
Another noteworthy issue is to distinguish between neutral line rows and ground line rows!
Usually the copper bars that have screws to connect the box are ground wire rows, and the copper bars that are not connected to the box are neutral wire rows! The ground wire is usually on the left and the neutral wire is on the right. Be sure to distinguish clearly before wiring. It is best to disassemble it and confirm it to ensure the safety of electricity use, so as to avoid the box being charged if it is cut off in the future!
line should be marked before bent, because it is easier for me to distinguish, so I used electrician tape to mark it!
This is the rendering of the wire connection. It should be noted that this is a four-story private residential building. The first four empty openings are the overall openings and the upper floor branch switches. The middle two 1P-16A are the first floor lighting and stair lighting, and the second two are 1P+N are the socket switches (circuit breakers).
Next, let’s talk about the situation on other floors:
The second floor is two bedrooms and two living rooms, one kitchen and one bathroom, the air opening wiring is as follows:
Total opening: P-40A empty opening, equipped with 10 square copper core wire
Lighting: 1P-16A empty opening, equipped with 1.5 square copper core wire
Ordinary socket: 1P+N-20A leak protection, equipped with 2.5 square copper core wire
HD 0 Kitchen socket: 1P+N-25A leak protection, equipped with 4 square copper core wire
Bathroom socket: 1P+N-25A leak protection, equipped with 4 square copper core wire
Living room air conditioner: 1P+N-25A leak protection, equipped with 4 square copper core wire Wire
bedroom air conditioner: 1P-25A is empty, equipped with 4 square copper core wire (shared in both rooms)
bedroom air conditioner and lamps are basically inconvenient, or they are plastic shells, so 1P is empty, which is also to reduce the space occupied by the electric box. This is all for the installation and wiring of
distribution box. Although it is not done very well, I am a person who pays attention to sharing. If you have any other insights, everyone is welcome to complain, criticize and guide!
