1. The Project Department shall make unified arrangements for temporary electricity utilization on site, and determine the replacement of required leakage protector, failed leakage protection and aging cable according to the actual situation on site.

2. The Project Department manages the temporary electricity consumption on the construction site in a unified way, and implements the system of examination and approval for electricity consumption of the construction team of the Project Department. It is forbidden to connect privately.

3, the preparation of temporary electricity construction organization design, site maintenance electrician should strictly implement the "JGJ46-2005" and "JGJ59-99 standard" three-phase five-wire system, completes the equipment shell protection and zero grounding, adhere to the electrician inspection and maintenance work, and fill in the records carefully.

4. Configure according to "three-level control and two-level protection". The last switch box ensures "one machine leaks", and the switch box should have rain-proof and dust-proof facilities.

5. Correct selection of the location of the power distribution room is of great significance to the rational layout, safe operation and improvement of power supply quality of the power supply and distribution system on the construction site. The distribution room should be as close as possible to the load center, so as to reduce the length of the distribution line and the cross section of the conductor, and try to avoid places where dust, humidity and high temperature vibrate, so as to prevent the erosion of the conductive parts and insulating parts of the distribution device by dust, humidity and high temperature and the influence of vibration on the operation of the distribution device. The distribution room should not be located directly below the place where water is easy to accumulate.

6, equipment grounding, zero and leakage protection device, electrician should be installed according to the specification requirements, and the implementation of regular monitoring and telemetry inspection.

7. When working under or on one side of the erection line, warning signs should be hung to ensure that the safe working distance stipulated by the state cannot meet the requirements, and protective fences and fences must be set up.

8, the project department belongs to the construction group electrician must organize regular training, after passing the exam, to show certificates.

9. "Three-phase five-wire system" must be adopted for power supply on the construction site. TN-S zero protection system must be adopted for direct grounding power supply of neutral point of special transformer. When the construction site and external power supply lines share the same power supply system, electrical equipment should be protected by zero connection or protective grounding as required, but some equipment should not be protected by zero connection and the other part should be protected by grounding.

10, all kinds of electrical equipment should be equipped with special switches and bolts, bolts should have special protective grounding and contacts. It is forbidden to connect the conductive contact to the ground contact by mistake.

1 1. Overhead power supply lines must be laid with insulated wires, special poles supported by insulators, cement poles, wooden poles or along the wall. Tension insulators must be installed for pole cables. It is forbidden to erect power supply lines on trees and scaffolding.

12. Overhead lines on the construction site shall be installed outside the slewing radius of the boom. If this requirement cannot be met, protective frames must be erected or other measures must be taken.

13, it is forbidden to use unqualified safety devices and moldy wires. The power cable of all mobile electrical equipment should be disconnected from the whole site, and the external insulation layer should be free from mechanical damage.

14. The horizontal safe distance between power overhead lines and buildings or temporary facilities under construction shall at least keep the values listed in the table below. If it is difficult to keep the above-mentioned safe distance according to the actual situation, technical measures should be taken for protection, and construction can only be carried out with the consent of the relevant power departments.

15, switch box must strictly implement the system of "one machine, one box, one brake and one leakage switch", and it is forbidden to directly control two or more electrical equipment including sockets with the same switch. It is forbidden to store anything in the switch box, and the door should be locked, with rain-proof and moisture-proof measures.

16. When removing lines at the construction site, the power supply must be cut off first, and it is forbidden to leave wires that may be charged.
