In home renovation, since the power lines, TV antenna wires, and telephone lines must be re-arranged according to the needs of the family's daily life, the circuit reconstruction project is an indispensable item. However, due to the low cost and short construction period of circuit projects, it is often overlooked by the people. Some construction teams take the opportunity to use their hands and feet, and the used materials are shoddy. In construction, only external effects at the time are taken into consideration, and safety factors and future maintenance are neglected. Convenient, to lay a serious security risk for the future home life. In order to ensure the quality and safety of circuit engineering, relevant professionals make the following suggestions:
â– Attention should be paid to construction personnel qualifications and material quality First, the construction personnel should have a post operation certificate issued within the validity period issued by the local labor department. Undocumented personnel should not engage in circuit construction. Secondly, the materials used should be branded products, or have safety certification marks (Beijing Great Wall Marking), some of the hardware stores sold in the hardware stores, non-manufacturers and production date of poor quality wires, sockets, etc. should be put to use, so as to Guaranteed safe service life. Household wires are best made of copper wire, with a diameter of 1.5 mm or better.
â– Adjust the capacity of the circuit according to the demand When the residential building is under construction, the circuit capacity is a fixed value. In the process of home renovation, the circuit needs to be modified, such as moving or adding power sockets for indoor use. Due to the large-scale use of air conditioners, microwave ovens, humidifiers, and kitchen appliances during actual use, the power consumption will be greatly increased, which will jeopardize the safe use of electricity. Therefore, in the home improvement, the capacity of the meter and the thickness of the wire were redesigned to avoid accidents during use.
â– Pipe laying strictly follows the operation specification
The general household wires should be laid at least three, one outlet line, one lighting line, one air-conditioning line, and some places require five lines, one for the kitchen and one for the bathroom. When laying, a thin groove of about 15 mm in depth shall be cut out from the wall, and the wire conductor shall be put into the wire bushing, and it shall be placed in the groove of the wall and smoothed with cement mortar. There should be a certain gap in the casing, which prohibits the conductors from occupying all the space in the tube. The junction box should be installed at all switches, sockets, and lamp positions. There must be no wire joints in the pipeline and it must be a complete long line. Where the electrical appliance is metal, it must be installed with a protective grounding wire to prevent electric leakage. The weak current circuit such as the telephone line, sound signal line should be laid separately from the general circuit, and the distance between the two sockets must not be less than 50 centimeters, so as not to interfere with the signal such as telephone, sound.
Some people nicked the ground when they were on the route. This is extremely unreasonable because the floors are generally thin. After nicking the slots, it will affect the bearing capacity of the floor. In addition, improper construction may cause floor leakage and cause neighborhood disputes. Therefore, it is better to route through the wall.
â– circuit acceptance to prevent miswiring
For the acceptance of circuit engineering, it is necessary to look at the switches and sockets first. The switches and sockets require a firm installation, a correct position, a positive panel, a clean surface, and close to the wall. Secondly, the dedicated small plug for the application test is tested on the socket, to see if the position of the phase line and the neutral line is correct. If there is any error, it is immediately adjusted to ensure that the line can supply power normally. At the end of the construction, do not forget to ask the construction company for a set of circuit completion drawings for future maintenance and replacement.
