Adhere to people-oriented values, is to make the economy more development, improve democracy, cultural prosperity, and live a happier; is deeply concerned that human development and human values, development of social and human development of rational unified, insisted in the material civilization, political civilization and spiritual civilization in the overall advancement of Socialist civilization to a higher level. Also want to see that person's value is not only meet your needs, also is to meet the needs of others and the community. Adhere to people-oriented, to strongly advocate every community member, serve others, beneficial to the community of people. The so-called Outlook, attitude is on the record, including who, how to create a record of achievements, how to evaluate performance, and so on. What values, what kind of Outlook. Adhere to people-oriented Outlook, is on the premise of respecting the interests and power of people, creating a popular, warm hearts, steady heart performance, creating \ements, and overall construction of well-off society and promoting the all-round development of people's performance.

3、配电箱及导线、开关选择
施工现场的开关设备主要由各种开关电器组合而成的配电箱、开关箱等,并成为整个临时用电系统的枢纽。为了确保临时用电的安全，配电箱和开关必须在技术上采取合理的组成结构形式，并与施工临时用电工程配电线路相适应，在保护面采用TN-S系统。本施工场地只用一条主干线对施工现场进行供电。
3.1、总配电箱的仪表可装箱门上。
3.2、总配电箱若没有设置一级漏电保护器，则分配电箱中必须装设漏电保护器。此时，总配电箱中漏电保护器的位置可用熔断器或具有短路和过载保护功能的自动开关代替，而分配电箱中熔断器位置应用漏电保护器（具有开关、短路和过载保护功能）取代。
3.3、工地用电设备的控制箱根据设备要求进行开关电器的结构组合。
配电导线截面一般根据用电计算允电流进行查表选择，可按下式进行计算：
IL=（K·P总）/（3U线COS￠）
3.4、各干线的线路中电流量的计算和导线的选择、开关选择 （1）L1干线（（总装车间变电所 总配电箱））

其中：K——机械暂载率，本施工场地取0.8
COSφ——功率因数本施工场地取0.85
代入公式
P1=0.8×1.05×319.9/0.85=316.14KW

I1=（K·P1）/（3U线COSφ）
其中： K ——系数取值本场取值为0.5
P1——临时用电L1干线中高峰时总量
U线——导线电压，本工程为380V COSφ——功率因数本工地取0.85
把各数值代入公式
I1=（0.5×316.14×1000)/( 3 ×380×0.85) =252.55A
在L1干线中由于其峰值单相电流为11.2A,查表可知, 本工地从总装车间重卡变电所引至总配电箱的供电线路，采用YJV3×150+2×70mm2的铜芯重型橡皮绝缘电缆可满足工地的施工用电需求。由于不存在大型机具的直接起动，故漏电开关选择额定电流300A,额定动作电流200mA，动作时间≦0.2S的漏电型开关，熔断式隔离开关选择额定电流400A的隔离开关。
五、选择配电箱与开关箱
1、配电箱、开关箱应采用铁板或优质绝缘材料制作，铁板厚度应大于1.5mm，箱电器应安装在金属或非木质的绝缘电器安装板上，金属板与电箱箱体应作电器连接。
2、配电箱、开关箱尺寸应保证其部开关电器的安装、接线、维修、操作便，以及符合有关规定的电气安全距离。
3、配电箱、开关箱的箱体上应焊接用作保护接零（接PE线）的所谓接地螺栓，亦可直接加装PE端子板；以及加装N线端子板（与箱体绝缘）。
4、配电箱、开关箱中导线的进线口和出线口应设在箱体的下底面，禁设在箱体的上顶面、侧面、后面或箱门处。进出线应加护套分路成束并做防水弯，导线不束不得与箱体进、出口直接接触。
