Zheng Hong took the voltage tester and meticulously spent more than ten minutes to confirm that all the circuits were completely powered off with no residual charge before waving to Lin Li: "Alright, come in."
"Here I am, Master Zheng, what can I do?" Lin Li stepped forward immediately.
"Grab that small yellow vacuum cleaner from my bag, along with the brush, dry cloth, and flashlight," Zheng Hong pointed to the tool bag:
"Your job is to clean the inside and outside of the distribution cabinet, including busbar rows and insulators.
After cleaning an area, check if the terminals, screws, and connections are loose, and see if there are any parts that are rusted, aged, or cracked. If there are, tell me immediately to register them."
"Don't worry, don't be afraid you won't do well, because I and Liu will check again what you've inspected, so we'll cover for you."
"Okay."
