What are the electrical wiring standards? Why?

<>First, the standard of electrician wiring

We will find that when the house is renovated, its water and electricity renovation is also a key point of decoration, because this is also a relatively private project, and its safety is also relatively high, so for electrical wiring, only when it reaches a certain standard can it be used safely, and it can be better maintained. Therefore, for some home improvement electrician wiring, it may have two forms, one is construction wiring, and the other is to install construction wiring by yourself. Because their standards are different, and their wiring methods are also different, we need to distinguish them separately, so that they will have comprehensiveness is also a better answer.

For some decoration companies to do electricians, the standard of wiring is to require specifications, and hydropower is also a relatively large project, its profit is relatively high, at this time it is necessary to plan well, but also standard, but also high-quality and good-looking, so there are these characteristics.

Second, it needs to meet the standards

His construction level is also to make a standard, we know that the level to determine the position of the switch and its height will generally be determined by an infrared level, so their company will have some hard standards to use the elastic level to determine this time and the ceiling level, the switch level and other levels, as well as a one-meter standard level. The next thing is to position the circuit wiring, so you have to do a good job of drawing before, according to some designs on the drawings, make some positioning on the wall, you will find that many renovated circuits have some basic finished models, so it is directly drawn on the drawings, which is more intuitive. It is also necessary to determine the location of the circuit through the owner, so as to better meet his requirements, if you want to make adjustments, it is also possible, so it is correct to make adjustments before, and it may be more troublesome to make adjustments after choosing.

They will locate according to switches, sockets, and lights, and then wiring them, and they will choose to go to the roof instead of the ground when wiring, and if there is really no way, they will choose to go to the wall; If all the lines are underground, it is very difficult to repair, and the floor tiles have to be lifted, which is easy to affect the structure of the house.

Strictly speaking, electrical wiring should be divided into several ways, such as direct wiring, metal conduit wiring, flexible metal wire protection sleeve wiring, metal trunking wiring, rigid plastic conduit wiring, and concealed metal wiring wiring in the ground.

The standard of electrical wiring is that the hydropower slotting should be horizontal and vertical, the layout is neat, the excavated wall can not have a horizontal groove, and the arc at the corner replaces the right angle to ensure the strength and weakness of the circuit, because it is necessary to ensure that the impulse line is convenient for later maintenance.

The standard is horizontal and vertical, because such wiring can achieve better utilization efficiency, and will not cause too much damage to the wire, and the wire will not be entangled or seriously damaged in the process of use.

For home improvement electrician wiring, because there are decoration construction wiring and self-installation construction wiring, there are two different wiring standards, so it is necessary to answer them separately, so that it is comprehensive and belongs to the high-quality answer.

Decoration company electrical wiring standards: for decoration, because it has its own electrical wiring specifications, plus hydropower is a large profit to make money, so in the construction will show the four characteristics of planning, standard, good look, and high quality. The specific cabling standards are as follows:

1.Elastic construction level: Before hydropower construction, the construction level should first be made, and then the height of the switch socket should be determined according to this horizontal line.

Due to the use of infrared level, many times it is directly replaced by instruments, but the decoration company has a rigid requirement, it is necessary to play the horizontal line, and it is divided into socket horizontal line, switch horizontal line, ceiling horizontal line, and 1-meter standard horizontal line.

2.Positioning of the circuit wiring: after the horizontal line is played, according to the design requirements of the drawings, the positioning of the wires is made on the wall, and some decoration companies have a finished circuit model, and the model is basically drawn directly on the wall, so that it can be expressed intuitively.

3.The owner determines the location of the circuit: After the location of the circuit is drawn on the wall according to the drawing, it is necessary to wait for the owner's determination again to avoid regrets and later changes, and then the construction can be carried out. If the owner wants to make adjustments, it is perfectly possible.

4.Slotting: After the circuit positioning is confirmed by the owner, the electrician can continue to draw the position that needs to be slotted according to the position drawn on the wall, and then slot.

Note that the line slotting should be horizontal and vertical, and at the same time avoid the appearance of long transverse slots, and the standard practice is not allowed to open transverse slots, because it will affect the bearing capacity of the wall.

5.Brush waterproof coating: For electrical cable ducts like bathrooms, waterproof paint should be brushed before construction.

Hydropower renovation is the focus of decoration, because it is not only a hidden project, but also a safe use factor. For electrical wiring, only when the standard is reached, can the wires hidden in the wall, under the ground and in the ceiling be used safely, and at the same time, it can also facilitate daily maintenance.

First of all, it is necessary to locate the circuit according to your use of electricity, for example, **to switch, **to socket, **to lamp, etc., the electrician will be positioned according to your requirements. In home decoration, it is necessary to involve strong electricity (lighting, electrical appliances) and weak electricity (TV, **, audio, network, etc.) electrical line buried dark line, wire is very important.

The standard of electrical wiring is to draw the construction level, set the position of the circuit wiring, determine the location of the circuit with the owner, play the circuit slot, paint waterproof, and pre-embed the electrical route.

The standard of electrician wiring is generally water to the top and electricity to the ground, and many families are like this, which is also a standard for them.

That is, the role of each line can be clear, it can be well arranged, and it can play a good role in layout.

1. In home decoration, it is necessary to involve strong electricity (lighting, electrical appliances) and weak electricity (TV, audio, network, etc.) electrical line buried dark line, wire is very important; Second, the selection of wire specifications: in home decoration, according to national regulations, lighting, switches, sockets to use square wires, air conditioning to use 4 square wires, water heaters to use 6 square wires.

1. Circuit installation of components in the distribution cabinet:

1. Before assembly, first read the drawings and technical requirements.

2. Check whether the product model, component model, specification quantity, etc. are consistent with the drawings. If there is any unclear or wrong in the drawing, it should be reported to the team leader or communicated with the designer.

3. Check whether the components are damaged.

4. It must be installed according to the drawings (if there are drawings).

5. The order of component assembly should be from the front of the board, from left to right, from top to bottom.

6. The assembly consistency of the components of the same model should be ensured.

Code for Electrical Wiring in Indoor Buildings, GB 1259

Lighting wiring is wiring. The light switch is at a height of meters from the ground and 20 centimeters from the wall.

Ordinary socket wiring adopts wiring. The height of the culvert is 30 cm above the ground.

The wiring of the air conditioner socket adopts 4mm2 wiring. The height from the ground is about meters.

What are the construction standards for wire wiring, let's learn together!

The hydropower slot is horizontal and vertical, and the line pipe in the trough is neatly arranged.

The slotted wall can not have a horizontal groove, the horizontal groove of the load-bearing wall cannot exceed 30 cm, and the non-load-bearing wall cannot exceed 50 cm. In order not to damage the load-bearing structure of the wall, the kitchen and bathroom have a roof and do not go to the ground, because the integrated ceiling should be installed, and it is more convenient for later maintenance.

The camberism at the corner replaces the right angle, which has the advantage of ensuring that the strong and weak lines are pumped at critical times, which is convenient for later maintenance and line change.

First of all, check the appearance of the waterway, there is a main water valve at the water inlet, and the laid water pipe is not scratched or damaged on the surface.

All waterways go to the sky, and when water and electricity are staggered, the circuit is arranged on the waterway. Hot on the left and cold on the right. The distance between the cold water pipe and the hot water pipe is about 15 minutes.

After the water pipe, do a good job of waterproofing to prevent condensation outside the water pipe wall, and all water pipes are fixed with copper wires to prevent the disturbance of the line pipe and water pipe, resulting in tile hollow valleys or wall cracks.

Natural gas pipes must avoid line pipes and water pipes.

Circuit precautions: Generally, the bathroom kitchen socket uses four square wires, and the ceiling lamp wires use squares. The main air conditioner is four square or six square.

All conduits must be live wires, there can be no joints, and the arc can not be right angles, in order to ensure that the wires can be twitched back and forth in the later stage, which is easy to maintain.

The distance between strong and weak current is 30 cm, separated and slotted, and the weak current is a single tube and a single wire. Keep the joints of all wires at 15 cm for future installation of conduit panels.

Tin foil is used for the crossover of strong and weak electricity, which will not interfere with each other's signals.

After all the switches and sockets are installed, they must be sealed before the next step of construction.

Check the circuit, generally the air conditioner is set up with a separate circuit, each room is set up with a circuit, and all high-power electrical appliances are set up with a circuit for rice cookers, water heaters, air conditioners, and large ovens.

Selection of wire specifications: In home decoration, according to national regulations, lighting, switches, and sockets should use square wires, air conditioners should use 4 square wires, and water heaters should use 6 square wires.

Horizontal and vertical, because this layout will make maintenance more convenient, and it will be easier to pull it out later.

The wiring standard is horizontal and vertical, the wires do not overlap, and the way of tiling is adopted.
