As we all know, hydropower engineering is one of the important steps in the home improvement process, and it is also known that hydropower is the hardest to accept! Because it is a hidden project, once the acceptance is not good, it will have a great impact on future life. Therefore, we must pay special attention to the decoration. Today, Xiao Bian gave everyone the opportunity to sort out the 10 most common mistakes in circuit decoration. I hope Can give everyone a wake-up call!
First, the circuit is not set properly
Home decoration is generally based on the use of electricity and electrical equipment, set up 5-8 loops, we have already introduced in front.
Second, indiscriminate use of wire specifications
The wires used in home improvement are single-stranded copper wires. There are three main specifications, 4.0mm2, 2.5mm2, and 1.5mm2. Each specification line is applied to different locations and cannot be used indiscriminately.
Third, do not set a dedicated line
Home improvement requires high-power electrical appliances such as air conditioners and water heaters to be installed with special lines so as to meet the requirements of the electrical load and ensure the normal operation of the electrical appliances and the safety of electrical power.
Fourth, the switch wiring error
The correct wiring method should be the switch phase (fire) line, the lamp is connected to the zero line.
Fifth, socket wiring error
The correct wiring method should be the right phase (fire) line, the left zero line, and the upper line.
Sixth, the circuit wiring is not standardized
The circuit layout must be horizontal and vertical, and all the wires must be PVC pipes.
Seventh, chaos and chaos
Shear walls, load-bearing walls, beams, columns, etc. cannot be destroyed, and yellow wax tubes or PVC bellows should be used for wiring.
Eighth, too much threading
The maximum number of threads that can be threaded in a PVC pipe can not exceed 8 and can not exceed 40% of the cross section of the PVC pipe.
Ninth, signal lines and power lines are laid with the same pipe
If the signal line and the power line are laid in the same pipeline, mutual interference will occur, affecting the use of television, telephone, network, audio and other effects.
Tenth, the entire circuit does not set the ground
The circuit decoration should pay attention to not set the bottom line, otherwise it will leave a major security risk.
