It is strictly forbidden to use hands to test, which will cause danger to the user.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; In case of broken electricity located above the galvanometer, the electricity branch must be notified to send workers to repair. If the damaged part is behind the galvanometer, it is imperative to cut the main circuit breaker before proceeding to repair the damage.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; It is necessary to ensure that the distance between 2 porcelain clamps or 2 adjacent porcelain pulleys is not too large, besides make sure the distance between the conductor and the structure is not less than 10 mm.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Construction of electrical conductor connection needs to be staggered and has insulation tape wrapped outside the connection, especially for the case of double wire.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Never close or cut circuit breakers, switches, etc. When your hands are still wet, it will transmit electricity, causing people to be electrocuted.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Only electrical equipment and electrical tools that have been grounded and connected without safety protection are allowed.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Construction and installation of circuit breakers, electrical switches on small wooden boards, and fasten them to walls or columns. The most reasonable place to mount the wooden board is about 1.5 m above the ground. Pay attention to the circuit breaker, the electrical switch must have a safety cover.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; The main lines in the house and each auxiliary line or electrical appliances in the house must have a protective fuse with a safety cover. The fuse-link of the protective fuse must be suitable for the use capacity to ensure that when there is a short-circuit, the fuse-link must explode and cut the circuit. The fuse-link must be installed according to the technical requirements. In a single-phase circuit, it is mandatory to put a fuse on the hot wire. If both wires are hot wires (2 phase wires), you must put fuses on both wires.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; The electrical conductors in the house must not use bare conductors but must use insulated conductors of reputable quality. It is necessary to select the electrical conductor cross-section in accordance with the ability to carry current to the power tools that it provides, to avoid the case of using a conductor with a small cross-section on power tools with too large capacity to avoid causing damage. serious electrical problems.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; When conducting indoor wiring installation, it is necessary to place it on clamps, porcelain pulleys or electrical conduit, which is usually made of plastic.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Make sure that the electrical wires through the walls and roof need to be placed in protective porcelain pipes. Avoid rain water standing in pipes or running down the house. The distance from the insulators supporting the end of the electrical conductor entering the house to the roof needs to be 2m or more.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; The installation location of circuit breakers and switches must be easy to disassemble, there are obstacles below, the place must be spacious and well-ventilated, ensuring that the closing and cutting of electricity is quick and timely.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Avoid installing electrical outlets, electrical switches, do not pull power cords through wet places, toilets or bathrooms.

In this section, we will go into depth and focus on the construction of electricity and water. In the electrical part, the construction team will proceed step by step in the following order:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_1_Install_the_power_line_protection_pipe_system\"><\/span><span style=\"vertical-align: inherit;\">Step 1: Install the power line protection pipe system<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">During the installation of the power line protection system, you should pay attention to strictly follow the agreed standards and design guidelines.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">In the current designs, architects often follow Vietnamese standards, IEC standards. This protective tube shall be flexible, high temperature resistant, impact resistant and readily malleable.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Usually, we put wall pipes and concrete floors. In areas of technical floors, pipes run floating on technical floors. The installation process is as follows:<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; The pipe system placed in the concrete floor is implemented right after the construction unit finishes weaving the floor iron layer: In places where there is only one layer of floor iron, the pipe will be placed right on the iron layer, in a position with two layers. iron floor, pipe will be placed between two layers of iron floor. At the turns, these pipes will be bent by springs, the radius is about 6 to 9 times the pipe diameter, ensuring that we can easily pull the wire and replace it later if something goes wrong.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; Absolutely do not use the connectors at the turns: because it will directly affect the pulling of the rope due to the sharp turn. At splits of 3 or more wire branches should be made in boxes.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">&#8211; The pipes waiting for the wire to be pulled must be covered: to avoid foreign objects entering and having difficulty in pulling the rope later.<\/span><\/p>\n<p><strong><span style=\"vertical-align: inherit;\">Note:<\/span><\/strong><\/p>\n<ul>\n<li><span style=\"vertical-align: inherit;\">When installing underground pipes: it is recommended to install and repair the wall when building the wall 5 days, so that the wall is sufficiently rigid, not cracked when punching the wall, and should only be chiseled after cutting the wall. In places where pipe cutting and splicing is required, the cutter head should be smoothed to avoid scratching the wire. The distance between the two joints is &gt;50mm compared to the middle of the pipe and &gt;25mm at the end of the pipe. Should be fixed by cement or concrete after being fixed by horizontal steel bar or steel wire column.<\/span><\/li>\n<li><span style=\"vertical-align: inherit;\">Pipes floating on technical floors, in technical boxes: must be fixed by hose clamps and the distance between clamps should be &gt;1200mm. Drill the screws and spacers to attach the hose clamp with an electric drill.<\/span><\/li>\n<li><span style=\"vertical-align: inherit;\">Standard for underground electrical conduit: the pipe going in the wall should go in parallel, with the last part being a box containing switches and sockets. Fix the tube to the box with a screw coupling, the recessed light box in the floor needs to be stuffed with paper, foam and covered with masking tape, to prevent the mortar from entering. The connection pipe must be &gt;7mm from the formwork, to avoid cracking bare crow&#8217;s feet.<\/span><\/li>\n<li><span style=\"vertical-align: inherit;\">Use the water scale to determine the position and elevation for the light box, switch box: make sure the boxes after installation are not tilted or skewed.<\/span><\/li>\n<\/ul>\n<figure id=\"attachment_3312\" aria-describedby=\"caption-attachment-3312\" style=\"width: 534px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3312 size-full\" title=\"Electrical construction process in civil works\" src=\"https:\/\/mcw663.com\/wp-content\/uploads\/2022\/10\/thi-cong-dien-nuoc-dan-dung-534x400-1.jpg\" alt=\"Electrical construction process in civil works\" width=\"534\" height=\"400\" srcset=\"https:\/\/mcw663.com\/wp-content\/uploads\/2022\/10\/thi-cong-dien-nuoc-dan-dung-534x400-1.jpg 534w, https:\/\/mcw663.com\/wp-content\/uploads\/2022\/10\/thi-cong-dien-nuoc-dan-dung-534x400-1-300x225.jpg 300w\" sizes=\"auto, (max-width: 534px) 100vw, 534px\" \/><figcaption id=\"caption-attachment-3312\" class=\"wp-caption-text\"><em><span style=\"vertical-align: inherit;\">Electrical construction process in civil works<\/span><\/em><\/figcaption><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"Step_2_Install_the_power_cable\"><\/span><span style=\"vertical-align: inherit;\">Step 2: Install the power cable<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Immediately after completing the installation of the pipe system and junction box, the next step is to install the cable.

Otherwise, the repair later will be extremely difficult and complicated.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Besides, you also need to note a few details:<\/span><\/p>\n<ul>\n<li><span style=\"vertical-align: inherit;\">The number of wires should only be &lt; 40% of the pipe cross section: This makes it easier to replace later. The wires should be distributed in the right area, in the correct color scheme in the design.<\/span><\/li>\n<li><span style=\"vertical-align: inherit;\">Install wires in the correct order and position in the diagram of electrical distribution cabinets: Connections should be made in plug boxes or light tray boxes.
