(1) The Project Department will 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 electricity consumption examination and approval system for the construction teams under the Project Department. It is strictly forbidden to connect electricity without permission.

(3) Prepare the construction organization design for temporary electricity utilization. On-site maintenance electricians should strictly implement the standards of JGJ46-2005 and JGJ59-99, implement the three-phase five-wire system, do a good job in equipment shell protection and zero grounding, insist on electrician inspection and maintenance, and fill in records carefully.
