1, circuit transformation involves the positioning of space, but also slotting, so it must be done in advance. It is forbidden to directly bury the wires in the plastering layer. No joints are allowed in the wire conduits. At the same time, the used wire tubes (PVC flame-retardant tubes) must be strictly inspected. The surface of the tube wall should be smooth, and the wall thickness must reach the finger and the pinch must not be broken. Strength, and should have a certificate of compliance. It is also possible to use a special galvanized tube of the national standard as a threading tube. To comply with national standards, the standard stipulates that a wire tube with a wall thickness of 1.2 mm should be used. The standard requires that the total cross-sectional area of ​​the wires in the tube not exceed 40 in the cross-sectional area of ​​the plastic tube. For example, a PVC pipe with a diameter of 20 mm can only wear 1.5 mm 2 cross-section wires and 2.5 mm 2 cross-section wires. However, some construction teams wear six or seven 1.5 mm 2 wires or five or six 2.5 mm 2 wires. The distance between the electric wire and the gas pipeline is too close to the allowable range of the standard; in accordance with the standard, the quality inspection shall be carried out at the end of each construction phase, and acceptance records shall be made. However, the unqualified construction team often does not have electric concealment work. Acceptance records. The principle of "safety, convenience, economy, and objectiveness" is followed for the laying of pipelines. At the same time, for special power circuits, such as air conditioners, baths, electric showers, etc., users are advised to check whether there is a protection device before purchasing, and then configure the corresponding leakage protection switch to ensure the user’s property. Safety. After the completion of the project, it is necessary to perform a leakage switch test and give a complete circuit diagram for future maintenance. 2, the choice of wire: For fire prevention, maintenance, and safety, it is best to use single-stranded copper wires with the “GB†plastic or rubber insulation protection layer of the Great Wall logo. The cable slot area is generally 2.5 square millimeters for lighting and outlets. Must not be smaller than 4 square millimeters, the connection line uses the green and yellow two-color line, then the switch line (fire line) uses any one of red, white, black and purple. However, the color of the thread used in the same home improvement project should be consistent. 3, switch panel, socket selection and installation requirements: The size of the panel should be consistent with the size of the embedded junction box; the surface is bright and clean, the brand logo is obvious, there are security signs and the national Great Wall logo of the electrical safety certification; the switch feels flexible when the switch is turned on, the socket is stable, and the copper sheet must have a certain thickness; The panel material should be flame-retardant and sturdy; the switch height is typically 1200 to 1350 mm, the door frame edge is 150 to 200 mm, and the socket height is typically 200 to 300 mm. >>> 20 Figure 45 flat sun married transitional housing Dwellings can also be converted into luxury homes Switch and socket optional air conditioning wardrobe brand switch socket layout space lighting Hexagon sleeve anchor ,Hexagon Sleeve Anchor,Hexagon Flange ,Hexagonal Casing Gecko Bolt Hebei Kangjin Metal Products CO.,Ltd , https://www.kjmetalproducts.com
