3.
wire slot removal If the conduit in the wall has space, it is best to use it.
4.
There should be no connector in home decoration, especially in the line pipe.
2、 Strong current, weak current layout and construction house decoration, strong current refers to the voltage not higher than 250V, such as electric lamp, water heater, refrigerator, etc.
（4） .
the required switches and sockets of strong and weak current shall be comprehensively arranged.
During construction, strong and weak electricity shall be separated, otherwise there will be interference.
The sockets of strong current and weak current shall be at least 30 cm apart.
There is a risk of damaging the conduit every meter.
Where strong and weak current intersect, wrap the weak current line with aluminum foil to avoid Xianhu interference.
First cut the conduit and use the holding spring to hold the bend at the corner.
（5） Now, if the connector is stressed, the wire should be wrapped with fireproof adhesive tape.
It is also the lightning rod conductor on the roof.
This is incorrect! （9） The ground wire and ground wire are not charged, but they can input the current to the earth to spread out when there are wires, short circuits in the electrical parts and the casing is charged, so as to protect the safety of people and machines.
There are many phenomena that there is no problem with water and electricity in the new house.
There is nothing wrong when the wire is not loaded, but as soon as the switch is pushed, the junction box will “pop” several times and trip! This phenomenon is all due to the nonstandard connector of the wire and poor contact of the voltage under load.
joint treatment in the wire box.
The first connection method: “two main lines collude and wind each other for 6-8 turns”, so as to ensure that the wire joint does not have ignition, short circuit and poor contact.
Because the heat of floor heating will accelerate the aging of wires.
The main line is bent and cannot be cut off, and the attached wire is wound around the main line for 6-8 turns.
Ensure that there is no conflict between strong current and weak current when the designed drawing is on the wall.
5.
Today, take a secondary ceiling as an example to talk about the correct practice of wire wiring! （1） During the construction process of wire end treatment, the end of each wire shall be treated in this way, which can effectively avoid the risk of electric shock, and also see whether the workers are professional from the subtle point of view! （2） The first method of wire connection.
There are several rules in this step: 1.
All wires should not be confused, (all switches are control live wires, (220V), zero wire (0V) ground wire.
Its function is to prevent electric fire from burning things, which is very important in the ceiling.
The beauty of the line pipe is not horizontal and vertical, but the nearest distance and the least bending is scientific, economic and reasonable.
Especially now many ceiling materials use wood as keel, which is more necessary (in the ceiling).
The wiring starts from the buried conduit.
（6） The third connection method.
Let’s talk about the connection method of wire ends in the junction box.
The following is the third connection method, which is the crimping method.

Looking at chaos is actually regular.
The depth of the trunking is the diameter of the trunking + 1cm plastering layer.
The red is the fire line, the basket is the zero line, and the flower is the ground line.
3.
2.
Its wide application has created great wealth for mankind and improved our life.
In addition, the size of the crimping line is related to the number of wires according to the size of the crimping line.
Generally, there is no elbow.
The crimping pliers for crimping the wire.
The fixing nut must be tightened.
It is best to use three colors for the three wires, and confusing the line items will cause short circuit.
The connector in the wire box does not meet the specification.
The following four common sense rules must be noted: 1.
However, we can not ignore the dangers hidden around us! Safe use of electricity is not only It is not as simple as pressing the switch with wet hands, and circuit installation is the top priority!..
（3） .
external power supply wire connection method this is the connection method when there is an external power supply in the line.
There is no doubt that electric energy is a convenient energy.
Weak current is generally within 24V, such as audio, video, network, telephone, TV lines, etc.
Weak current and strong current can be in one trunking, but not in one conduit.
Some workers connect the wire after opening it and simply deal with it with adhesive tape.
Therefore, when doing the project, it is best to find the property company to provide drawings, so that the original line pipe will not be damaged when cutting the groove later.
Electricity is indispensable to every family, and the safety of electricity can not be ignored.
Here is a hint that the ink line traces of weak current and strong current should be snapped first, but when slotting, the sequence of strong current before weak current should be done step by step, which can not be confused.
5.
When the branch line is connected to the main line, the main line cannot be cut off, and the attached wire is wound around the main line for 6-8 turns.
However, there are always some families who are damaged due to improper circuit construction, and even pay their lives! This article is the painstaking work of an old technician who has been engaged in home circuit construction for 10 years! If you want to build a house, you can definitely use it! 1、 Wire wiring methods and precautions we have seen many wire accidents.
Some are caused by wire overload and the other is caused by loose wire joints.
buried conduit and wiring.
There shall be no connector (including strong and weak current) in the conduit 。 4.
Make a conduit before stringing.
Put the special pliers for crimping the wire on the crimping cap and press it hard.
Even if there is a connector, it should be in the wire box.
It can ensure that the wire connector does not have ignition, short circuit and poor contact with the.
（2） After the line layout is completed, the ink line can be snapped on the wall.
precautions for wiring in the junction box: ignition, short circuit and poor contact of wires are not only in the connector, but also in the junction box.
2.
The joint in the wire box should be treated with a set of wire cap.
（3） The second connection method of wire connection is also stipulated in the construction specification.
The commonly used T4 type is mm in diameter, which can press four wires of 4mm2.
This method is the most standardized and practical, but it needs special tools.
Now many people do floor heating, and those who wiring underground should be close to the wall as much as possible.
（4） .
（1） .
After the decoration, the problem will come.
Its importance can not be ignored! This is the underground part of the ground wire, which can effectively release electric current and strong potential.
