Temporary use of electricityHow safety managers learn temporary electricity codes
OneHow safety managers learn temporary electricity codes
There are two main specifications, namely the "Safety Code for Electricity Supply and Consumption on the Construction Site of Construction Projects" (GB50149-2014) and the "Technical Code for Temporary Electricity Safety on Construction Sites" (JGJ46-2005). GB50149-2014 directory division is more reasonable, there is a certain logical order, I will simply summarize the national standard specifications, and re-divide them according to the daily management of temporary electricity. If we look at temporary electricity consumption as a whole and as a system, it can be divided into seven parts in a certain order and a certain logic, which I call the "seven-step method of temporary electricity management".
The actual construction sequence is also as follows: the first plan - installation of generators or transformers - installation of power distribution facilities (power distribution room, distribution box, switch box) - placement of electrical equipment (power facilities, including lighting) - connection of cables - organization of acceptance - daily hidden danger investigation (maintenance, inspection, etc.). This is the temporary power management system, and other things such as lightning protection and grounding, and power supply in special environments are counted as exceptions, and they can be mastered separately.

It is necessary to have methods, routines, systematic thinking about problems, and strategic solutionsDesign
Excerpted from Xu Jiajun, former vice president of Huawei, "Letter of Resignation to Ren Zhengfei".
The problem of temporary electricity consumption should also be systematically considered, systematically studied, and standardized learning can be done from point to line, from line to surface, step by step to form a knowledge network, form a knowledge system, form a knowledge whole, so that the relevant knowledge points will be more firmly grasped, and the application will be more flexible. In the inspection, when encountering a potential safety hazard of electricity, it can be touched and inferred.
