Wire laying must pay attention to killing hidden dangers in the cradle!

Many times, we have problems like this when laying electrical wires. For example, if there is only one circuit at home, once it is short-circuited, all of the power will be lost. This will cause great changes to life, and as a hidden project, once there is no It is not only time consuming but also laborious and costly to shop and change. Therefore, we must do a good job of planning before laying, and prevent this from happening!

Misunderstanding 1: There is only one loop

Not only the former house, but also a lot of houses now exist in the same situation, that is, there is only one circuit in the home. Once any circuit is short circuited, the power consumption of the entire room will be paralysed.

Suggestion: When we lay out the display, depending on the area of ​​use, the lighting circuit can choose two or three ways and the power socket can be three to four. The kitchen and toilets each take one route, with air-conditioning circuits two to three, and one air-conditioning circuit with two air conditioners. In this way, when one of the loops fails, the other loops can still supply power normally, which will not bring too much influence on normal life.

Misunderstanding 2: Wire color separation is not clear

The circuit reform often sees that “there is no specific requirement for the color of the wire, as long as the colors of the wire, the neutral wire, and the ground wire are separated.” The condition that the color of this wire is used at will will exist in the future use and maintenance process. Security risks. For example, when the circuit is modified to facilitate the drawing and save the materials, the blue line is used for the fire line and the zero line. In the future, the maintenance master is not easy to find out the fire line and the zero line, which brings inconvenience to the maintenance and may cause construction safety accidents.

Suggestion: Regarding the color of the wire, it is expressly provided for in the considerable specifications of the electrical industry in China. Red is the FireWire color scale, blue, green or black is the zero line color scale, and the yellow-green color line is the ground line color scale. In a house, color patches need to be clearly identified and uniform color separation is used during installation. If there is no uniform separation of the installed lines, it is recommended that you mark them on the left side of the line and clearly mark them on the circuit trend chart for later review.

Myth 3: Bend straight pipe at tube bend

It is possible to bend the tube directly at the tube bend, but it is not good. If you do not pay attention to the work when the wire is bent, it will cause a lot of inconvenience later. If the wire is directly bent, it can easily cause damage to the wire and cause leakage accidents.

Recommendation: Although the electric pipe should not be bent directly, it is forbidden to use elbows at the turn of the electric pipe. The bent position of the wire protection tube should use the matching elbow tool or matching elbow, and there should be no folds. Increase the camber at the bend and cushion the camber pressure to reduce wear.

Misunderstanding 4: Wires are buried directly without casing

Some irresponsible contractors buried the wires directly in the wall during construction. The wires were not covered with insulating tubes, and the wire connectors were directly exposed. This could easily lead to potential safety hazards. In the future life, the wires lacked protection and were easily Rats snapped or suffered external damage, resulting in short circuits.

Suggestion: The specification of the laying of the wires is clear, and the outer wires must be protected by insulating sleeves. The joints cannot be exposed. Therefore, at the time of construction supervision, the owner must know.
