Xiao Bian If you want to know just the decoration of the home network's take a look at it. First, the basic requirements of the construction distribution box 1. The production of distribution box (cabinet) shall comply with the special requirements of GB7251.4 for complete construction equipment (ACS) and "Safety Technical Specifications for Temporary Use of Construction Sites" in Part IV of Low Voltage Switchgear and Control Equipment. 》JGJ46-2005 standard requirements. 2. The installation and use of distribution boxes (cabinet) and switch boxes shall comply with the JGJ46-2005 standard for "Safety Technical Specifications for Temporary Use of Construction Sites" and the GB/T13869 standardization requirements for "Safety Guidelines for Electricity Use". Electrical components should be selected in accordance with GB/4048.2-2001, GB6829 and JGJ46-2005 standards, and in line with the Ministry of Construction "Eleventh Five-Year" promotion and application of technical requirements. 3. The distribution box (cabinet) and switch box should be divided into N line and PE line terminal boards. The input and output lines must be connected reliably through the terminal board. The N-line terminal block must be insulated from the metal electrical installation board; the PE line terminal block must be electrically connected to the metal electrical installation board. The N wire in the incoming and outgoing wires must be connected through the N wire terminal block; the PE wire must be connected through the PE wire terminal block. The PE wire must be electrically connected to the terminal block. The number of electrical connection points should be two more than the number of circuits in the cabinet. One is the connection point of the PE wire into the cabinet, and the other is the connection point of the repeated grounding. Second, how to set up the distribution box 1. The main distribution box should be located in the area close to the power supply. The distribution electric box should be located in the area where the load of the electric equipment is relatively concentrated. The distance between the distribution electric box and the switch box must not exceed 30 meters. The switch box is fixed with its control. The horizontal distance of the electrical equipment should not exceed 3 meters. 2. The distribution box and switch box should be located in a dry, ventilated and normal temperature place. They should not be installed in gas, smoke, steam, liquid and other harmful media with serious damage, and should not be installed in foreign solids. Impact, strong vibration, liquid immersion and heat source baking, otherwise special protection must be taken. 3. There should be enough working space and passages around the distribution box and switch box. Do not stack any items that interfere with operation and maintenance, and do not use shrubs or weeds. 4. The distribution box and switch box should be installed correctly and firmly. The mobile power distribution and switch box should be installed on the solid bracket. The vertical distance between the center point of the fixed distribution box and the switch box and the ground should be greater than 1.4 and less than 1.6 meters. The vertical distance between the center of the mobile distribution box and the switch box should be greater than 0.8 and less than 1.6 meters. 5. The electrical appliances in the distribution box should first be installed on the metal or non-metal wood insulated electrical installation board, and then fully fastened in the distribution box, and the metal plate and the iron distribution box should be electrically connected. When building a house, the electric box will be installed, because each building will use electricity, so the electric box is also indispensable, then the basic requirements and how to set up the distribution box, everyone through the above introduction Understand, if you still want to know more about decoration, please continue to pay attention to the decoration home Internet cafe.
