1. The construction personnel should have a post* issued within the validity period issued by the local labor department.
Second, the materials used should be national standard products, or have a safety certification mark (Beijing Great Wall mark) to ensure the safe life.
Third, the construction should strictly implement the norms and process standards
1. When carrying out various line shift transformations, first determine the position of the line terminal socket, and draw the exact position and size on the wall surface. Then, proceed to the nearest similar socket lead and the lead method is: if the socket is in the wall The upper part of the wall is vertically slotted upwards to the top of the wall where the decorative corner line is installed; if it is in the lower part of the wall, it is vertically slotted downward to the bottom of the skirting board. The groove depth is about 15 mm, the wire conductor is loaded into the sheath, and it is placed in the wall groove and smoothed with cement mortar to fix it in the wall. If the original socket is reserved, reinstall it in its original position. If it is not retained, block it with cement mortar after filling it with bricks. The wire along the ground, when installing the skirting board, lies on the inner side of the bottom of the skirting board. The wire along the top corner is concealed inside the decorative corner line when the decoration line is installed.
2. The construction specifications of the circuit renovation project should be consistent in terms of the depth of the trench and the top of the slot line. After the control line is ejected on the wall, the wall surface is cut with a marble machine to manually slot. When installing the circuit, the bushing must be added. The connection of the bushing should be tight and smooth. The corner inside the corner should be cut and the arc-shaped interface on one side of the incision should be cut and installed. After the wire is installed into the casing, the wire fixing clamp should be used. After the wire is fixed in the wall and the wall surface, it is concealed by plastering or concealed by the skirting board and the decorative corner line. The installation of the outlet box shall be preceded by a hole in the wall. After the wire is inserted into the box, the box is placed into the hole and the wire is fixed to the panel and the panel is fixed on the box. The method of installing the power switch is the same as that of the outlet box.
3, copper wire should be used, and according to the use of capacity to configure. Not too thin. It is recommended that the wire diameter of the air conditioner should be 4 square millimeters of wire; the socket should use 2.5 square millimeters of wire; and the general lighting fixture should use 1.5 square millimeters of wire. When wires are routed through the hollow floor, they must be piped; wires of different voltages such as lighting lines, telephones and television lines must not be put in the same pipe; the power outlet panel should be the left zero line, the right phase line, and the upper ground line. Wrong; zero line, phase line, ground wire with different colors.
4, the wiring application of the dark pipe wiring construction, electrical wiring, the dark pipe laying requires the use of PVC pipe, open wiring must use PVC trunking. Avoid cracks on the wall caused by the pick-off during construction to destroy the wall structure. When laying, the number of conductors used in the pipe should be changed according to the number of conductors. Within the same pipe, it should not exceed four. It is forbidden that the conductors will occupy the space in the pipe. Air conditioners, lighting, and outlets should be shunted and controlled, usually at least four ways. Lighting goes all the way, air conditioning goes all the way, socket goes three to four ways. The advantage of this is that once a circuit has a short circuit or other problem, the scope of power outage is small and it will not affect the normal operation of other circuits.
The distance from the power line to the telephone line and TV line should be greater than 50 cm. The pipeline should be fixed with the structure. The junction box should be installed at all switches, sockets, and lamp positions. In addition, if the pipeline is too long or there are too many corners, a junction box should be set at a certain distance. No wire connector is allowed in the pipe. The bent position of the wire protection tube should use the matching elbow tool or matching elbow, and there should be no folds. The distribution control switch should be reasonably configured according to the specifications. If the configuration is too small, it will cause inconvenience in use. If it is too large, it cannot guarantee the safe use of electricity. Another important point is that during construction, the pipeline should be installed first, and then the conductors should be used. This avoids the possibility that the wire cannot be twitched when the line is changed in the future. Also to remind you is that when your home improvement project is completed, don't forget to ask the construction unit for a set of electrical circuit completion drawings for your future maintenance.

Aisle Lighting is a lighting solution used in commercial and retail environments to provide appropriate lighting for areas such as walkways, aisles, and passageways. Its goal is to ensure that these areas are bright enough to provide safety and comfort and to guide people's walking flow.
The design of walkway lighting needs to take into account different factors. The first is the intensity and uniformity of lighting, ensuring that the corridor area has enough brightness so that people can see the surrounding environment and the direction of travel. The second is the color temperature of the step led lighting, according to the needs of the scene choosing the right color temperature, such as a warmer color temperature can create a more warm and comfortable atmosphere.
Channel lighting also needs to focus on energy efficiency and sustainability. Choosing high-efficiency lighting technologies, such as LED fixtures, can reduce energy consumption and extend service life. Using intelligent lighting systems, combined with sensors and timers, automatic dimming and automatic shutdown can be achieved to save energy.
With the right aisle definition, businesses can create a safe, comfortable, and inviting shopping environment for customers. Bright aisle lighting not only enhances the shopping experience but also facilitates customer flow and navigation, helping to boost sales. In addition, proper channel lighting helps to reduce the risk of accidents and ensure the safety of employees and customers.
