1. Crooked irregular stay wire

the inclined wire on the wall is not only unsightly, but also very irregular. When the owner wants to install other things in the future, it is easy to touch the wire

prevention method: the slotting of wires must be horizontal and vertical. The line pipe shall be fixed at about 10 cm of the offline box and 10 cm of the ground turning. The distance of the fixed clamp on the ground is within 15 to 20 cm, so as to ensure the firmness of the wire pipe and facilitate the pulling, inspection and maintenance of wires in the future

2. There are too many line joints and improper joint handling

some lines are too long, and some joints will be produced during electrician operation. However, because some electricians are limited by their technical level or have a weak sense of responsibility, they do not do a good job in wiring, insulation and moisture-proof treatment of the joint, which will lead to open circuit, short circuit and other phenomena

prevention method: try to reduce joints in the line. If wiring is necessary, the distribution lines should be well connected, insulated and moisture-proof. If conditions permit, it can also be " Rinse tin " Or use wiring terminals; The coaxial cable connection of TV antenna is best to use a splitter or junction box, and the practice of telephone line is similar to that of TV line

3. The line with concealed treatment has no casing

the casing is to protect the concealed line from damage. If the casing is not sleeved or inappropriate casing is used, the damage of the line cannot be avoided during construction or in the future, which will leave hidden dangers for the owner

prevention method: PVC rigid conduit shall be used for concealed lines on the wall, and attention shall be paid to matching with the wire number; Minimize ground routing. In case of wiring on the ground, considering that it will be under pressure for a long time in the future and will be affected during construction, it is best to use water and gas pipes with PVC pipes inside to install the wire, and it should be fixed well to prevent it from moving

4. The completed lines are damaged by subsequent construction

the common ones are: the wall lines are broken by electric hammers, and the air nail gun pierces the PVC conduit or sheath wire when paving the floor, etc

prevention method: mark the concealed lines to avoid inadvertent damage by the construction personnel of the next process

5. The small horse pulls the cart

the distribution line does not consider that the wires of different specifications have different rated currents, " A small horse pulls a cart " The line itself is overloaded for a long time

prevention method: pay attention to its rated current when selecting distribution lines and wires

6. All kinds of different lines go through the same pipe

if the TV antenna, telephone line and distribution line are threaded into the same sleeve, the reception of TV and telephone will be disturbed

prevention method: TV antenna line and telephone line shall be sleeved respectively
