What are the basic safety requirements for temporary electricity construction in decoration and deco

1. The electricity used on the construction site shall comply with the provisions of the "Technical Code for Temporary Electricity Safety on the Construction Site" (JGJ 46-2003).

2. The grounding form of the electrical system at the construction site adopts TN-S system, and the metal shell of all electrical equipment must be connected with the protective line PE.

3. The head end of the power supply line of all electrical equipment on the construction site must be equipped with a leakage protection device, with a maximum action current of 30mA and instantaneous action.

4. When the high-temperature parts of lighting, electric heaters and other equipment are close to non-A-grade materials, or the wires pass through the decoration materials below B2 level, A-grade materials such as rock wool, porcelain pipes or glass wool should be used for heat insulation. When lighting fixtures or ballasts are embedded in combustible decoration materials, they should be separated by thermal insulation measures.

5. The shell and floor of the distribution box should be made of non-combustible materials, and the distribution box, switches and sockets should be installed on non-combustible materials.

6. The wire near the halogen tungsten lamp should be sheathed with heat-resistant insulating material, and the wire with flammable insulation should not be directly used.

7. The exposed plastic wire should be protected by a pipe or a wire groove plate.

8. At the end of each day's work, the temporary electrical equipment should be disconnected from the power supply, and the construction site should be cleaned up, so as to achieve the civilized construction of "clean site after completion of work".

Hello dear, glad to answer for you; The temporary electricity scheme and measures for decoration and installation are as follows; 1. Personnel management 1. Installation, maintenance or dismantling of temporary electrical projects must be completed by electricians. The grade of electrician should be commensurate with the difficulty and technical complexity of the project. 2. All kinds of electricity users should do:

1) Master the basic knowledge of safe electricity use and the basic performance of the equipment used. 2) Before using the equipment, it is necessary to wear and equip the corresponding labor protection equipment according to the specified rubber type, and check whether the electrical devices and protection facilities are in good condition. It is strictly forbidden to bring the equipment"Disease"Running.

3) The deactivated equipment must be turned off and the switch box must be locked. 4) Responsible for protecting the load line of the equipment used, protecting the neutral line and the switch box. Problems are found and reported and solved in a timely manner.

3. The electricity unit must establish a responsibility system for electricity safety and clarify the person in charge of electricity use. The personnel on duty and maintenance personnel must master the necessary electrical knowledge, pass the assessment and obtain the certificate, master the electrocution rescue method and artificial respiration method, and often participate in safety learning.

Legal analysis: 1) ** When working on the road or overhauling equipment, the safety technical measures that should be taken are: cut off the source of electricity; electrical inspection; installation of temporary ground wires; Laying temporary fences and hanging temporary signs.

2) In some special circumstances, when it is necessary to work with electricity, it should be carried out in strict accordance with the safety regulations of live work. When carrying out live work on low-voltage electrical equipment or lines, you should use qualified tools with insulated handles, wear insulated shoes, wear insulated gloves, and stand on dry insulated objects, and at the same time send a special person to supervise them.

Legal basis: Electric Power Law of the People's Republic of China Article 52 No unit or individual shall endanger power generation facilities, substation facilities, power line facilities and related auxiliary facilities. Blasting and other operations that may endanger the safety of power facilities or holes around power facilities shall be carried out in accordance with the provisions on the protection of power facilities, and the operation can only be carried out after approval and measures to ensure the safety of power facilities are taken.

Requirements: 1. The distribution system should be equipped with indoor general distribution boxes and outdoor distribution boxes or outdoor general distribution boxes and distribution boxes to implement hierarchical power distribution.

2. The power distribution box and the lighting distribution box should be set up separately, if they are placed in the same distribution box, the power and lighting circuits should be set up separately, and the wiring of the lighting lines should be on the upper side of the power switch.

3. The switch box should have a final distribution box, and the switch box should have a machine, a gate and a leakage, and each electrical device should have its own switch box, and it is strictly forbidden to use a switch appliance to directly control two or more electrical equipment.

4. The general distribution box should be located close to the power supply, and the distribution box should be installed in the area where the electrical equipment or load is relatively concentrated, and the distance between the distribution box and the switch box should not exceed 30m, and the horizontal distance between the switch box and the fixed electrical equipment controlled by it should not exceed 3m.

5. The distribution box and switch box should be installed in a dry, ventilated and normal temperature place, and shall not be installed in gas, flue gas, steam, liquid and other harmful media with serious loss. It shall also not be installed in places that are susceptible to the impact of foreign solids, strong vibration, liquid splashing and heat source baking. There should be enough space for two people to work at the same time around the distribution box and switch box, and no items that hinder operation and maintenance should be stacked around it.

6. The installation of the distribution box and switch box should be upright, firm and mobile, and the mobile box should be set on a solid bracket. The vertical distance between the lower skin of the fixed distribution box and the switch box and the ground should not be greater than or less than. The mobile distribution box and switch box are made of iron plate or high-quality insulating materials.

The thickness of the iron plate should be greater than.

7. The inlet and outlet of the wire in the distribution box and switch box should be located on the bottom surface of the box, and it is strictly forbidden to be located on the top, side, back or door of the box.
