In the basic part of home improvement, circuit design transformation is the most important thing, and you must not act rashly. Generally speaking, the indoor circuit design and transformation mainly depends on the owner's use requirements, home layout, decoration style and home appliance purchase situation, and the original lamp, switch, socket and outlet position determination scheme. Therefore, in the pre-circuit design, it is necessary to comply with the relevant technical requirements and specifications to ensure the quality and safety of the construction to avoid repeated modifications during or after the construction.
Master Wei of the home department advised that you should not underestimate the design and modification of the circuit. It is very important for the home improvement project. Even if there is one outlet, TV or telephone outlet, it will cause inconvenience. Therefore, it is recommended that you plan as much detail as possible in the early stage of design and renovation, so as not to bring trouble to the later stage.
Because the circuit reconstruction needs professional staff to complete, although the owners will not be as close as they are to buy some main materials, but they will master some knowledge about the “electricity†of the home in advance, and they will have their own circuit renovation projects and future use and maintenance. The benefits.
1. At the entrance of the house, it is necessary to install a distribution box with three protection switches with overcurrent protection, overvoltage protection and leakage protection;
2. When wiring indoors, the socket circuit and the lighting circuit should be separately routed. The socket circuit should be a single-strand insulated copper wire with a cross-section of not less than 2.5 square millimeters. The lighting circuit should be a single-strand insulated copper wire with a cross-section of not less than 1.5 square millimeters. Generally, a plastic sheathed wire can be used;
3, open the dark box to avoid the steel bars to avoid, can move up and down or even change the position, prohibit the broken ribs; it is forbidden to open the long tube in the wall to walk the electric tube. The load-bearing wall is easy to damage the structure, and the long-distance broken bar of the light-weight wall will also cause trouble. No special circumstances, the wire tube should not go inside the plaster line, easy to cause dead end dead line; PVC wire pipe is completed, need to use PVC glue to bond the interface;
4. The ground in the wet area of ​​the bathroom should not be taken away; if it can't be avoided, the ground must be laid with the whole pipe, and the pipe joint should not be left;
5. When the specific wiring is used, the plastic sheath or other insulated wires used shall not be directly buried in the cement or lime powder layer; in addition, the wiring of most households will not be completely constructed according to the drawings, and the accurate wiring drawing files will not be saved. Therefore, in order to facilitate future maintenance, all wires must be buried in the pipe;
6, the living room air conditioning (air cabinet air conditioning) socket height is 300mm from the ground, and the hanging air conditioning socket height is 1800mm from the ground; ordinary socket and weak power socket height is 300mm from the ground, and the spacing is 300mm; kitchen and bathroom socket is generally designed to be 1500mm from the ground , Yuba socket is 2100mm, range hood socket is 1800mm;
7. The spacing between the strong and weak wire junction boxes is ≥500mm under normal conditions, and the parallel spacing of the ground is not less than 200mm. The weak electric wires, especially the copper shaft cables, must use multi-layer shielding function cables;
8, PVC wire tube dark application specifications, 2.5 square BV wire with a diameter of 16mm tube, 4 square BV wire with a diameter of 20MM tube;
9. Strictly abide by the design scheme. The strong and weak electric wiring scheme is used to open the slot. When the length of the line tube exceeds 15m or there are two right angle bends, the cable box should be added or the right angle bend radius should be increased. If there are too many bends in the buried pipeline, when laying the pipeline, the route should be laid according to the design drawings and the site conditions according to the nearest distance;
10. Strong electric power lines and weak wires such as telephone lines, TV lines, network cables, and audio cables shall not penetrate into the same pipe; strong electric wires and pipes, gas pipes, and weak electric pipes shall not be covered with the same groove.
The line must follow the switch and socket
The circuit design transformation begins with the position determination of the switch socket. To determine the position of the switch socket, it is necessary to first consider how to plan and arrange each room in the future. For example, in the design planning, the master bedroom, the second bedroom, the study room, etc. should be determined, so that the future use can be taken into consideration in the specific wiring. Secondly, it is necessary to consider the placement of major electrical appliances and furniture, televisions, refrigerators, cabinets, bookshelves, etc. Of course, all of this must be based on the living habits of the owners and family members. For example, families who like to watch TV while eating food should consider installing fiber optic outlets in the dining room. According to the arrangement of most indoor indoor rooms and the layout of home appliances and furniture, the planning and reference recommendations for the switches and sockets of various indoor spaces are as follows. You can make appropriate adjustments according to your own needs.
