Check the circuit when the new house is checked Check the circuit configuration diagram
You should ask the real estate developer to provide a detailed circuit configuration diagram. There should be a circuit diagram of the distribution box of the household, indicating the selected switch, wire size, and the direction of the wiring. You can also judge whether the layout of the circuit is reasonable or not. Then, you can turn on all the light switches to see if the light is on, and check whether the electrical products and materials in the house are all in compliance with the current national standards; if the conditions permit, you should also use a multimeter to check the socket for power, and use the phone. The machine checks whether there is a signal on the telephone line and uses the antenna to check the signal of the television antenna.
The second step to check the matching appliances
After the pipeline inspection, you should perform the most important job, electrical safety inspection. Open the distribution box in the room to see whether the configuration in the distribution box is reasonable and whether the specifications meet the national regulations. There must be enough branch circuits in the distribution box. Lighting, air conditioning, sockets, kitchens, and bathrooms must be provided with independent circuits, and must be guaranteed to be 16A. There must be a leakage switch in the distribution box, because with the leakage switch, in the event of a leakage phenomenon, such as electrical shell charged, personal electric shock, etc., leakage switch will automatically trip.
The third step to check the switch socket
After reading the distribution box, you should look at the wall switches and outlets. First, check the number of outlets. The number of sockets should be sufficient for the use of various electrical appliances, so as to avoid the potential safety hazards caused by unwieldy wires. Secondly, switches and sockets should be selected in the correct position and firmly installed on the wall. The height of switches or sockets in the same room should be the same. Again, it depends on the quality of the product. Good products generally have smooth, smooth surfaces, uniform colors, and rich texture. Such as Merlin Gerin, Siemens, Longneng, etc. are more recognized brands.
Step 4 Check the wiring in the house
Check whether the wiring is normative and safe. For example, there must be no exposed conductor inside the suspended ceiling; it is forbidden to directly bury the wires in the plastering layer; all distribution wires, including strong and weak wires, should be laid with a sleeve, and strong and weak electricity must not be put on the same tube. The distribution wire should not have knots and kinks in the pipe; double-insulated the power wire connector with insulation tape and waterproof tape after the wire is passed; the protective ground wire of the three-hole power socket should be laid separately and must not be Neutral (neutral) mixed.
Electric experts said that in the household electrical installations should determine the concept of "safety and power integration," that emphasizes the terminal electrical appliances to the patch panel, and then to the wall switch socket, from each distribution box to the community distribution Electric boxes are all part of the household power distribution system. Users can only choose guaranteed electrical products at every stage to ensure the cooperation of low-voltage electrical products and terminal electrical products, and ensure the safety of the entire home distribution system.
