As we all know, hydropower is an important project in the renovation. If it is not done well in the early stage, it will not only be time-consuming and laborious after that. If it is not done properly, it will bring some serious security risks.
At this point, the editor sincerely recommends that you ask more about which decoration company has done a good job in hydropower before the renovation. The good here is first, the quality is good, and the second is the construction specifications.
In case the master does n’t understand, you have to learn more about it. The editor will come to talk with you today about some common mistakes and solutions to wire laying. If you see it, you must avoid it.
One. No wire layout
Everyone needs to confirm whether the positions of all switches and sockets are consistent with the design drawings and whether the quantity is correct. When doing circuit planning, air conditioner power sockets, kitchen power sockets, bathroom power sockets, other power sockets and lighting power sources should all be designed with separate circuits to avoid a short circuit that affects all electricity. However, it should be noted that the total capacity of each sub-route can not exceed the total capacity of the incoming line.
Two. There is only one circuit
Not only the former house, but there are still many houses in the same situation, that is, there is only one circuit at home, and once any line is short-circuited, the electricity consumption of the entire room will be paralyzed.
Suggestion: When laying the dotted line, according to the area of ​​use, the lighting circuit can choose two or three, and the power socket three to four. The kitchen and the bathroom each take one route, two to three air-conditioning circuits, and one air-conditioning circuit with up to two air conditioners. In this way, when one of the loops fails, the other loops can still supply power normally, and will not have too much impact on normal life.
3. Unclear wire color separation
It is often seen in the circuit transformation that "the color of the wire does not have any specific requirements, as long as the color of the live wire, the neutral wire, and the ground wire are separated." This kind of wire color can be used arbitrarily in the future use and maintenance process Security risks.
For circuit convenience and material saving, the blue line is used for the live line and zero line during the circuit modification, and it will be difficult for the maintenance master to find out the live line and the zero line in the future. This will cause inconvenience for maintenance and cause construction safety accidents.
Suggestion: The color of the wire is clearly stated in the considerable specifications of China's electrical industry. Red is the fire wire color code, blue, green or black is the zero wire color code, and the yellow-green color wire is the ground wire color code. In a set of houses, the color scale needs to be clearly distinguished, and uniform color separation is used during installation.
If the installed line does not have a uniform color separation, it is recommended to mark the line on the left and mark it clearly on the circuit diagram for future review.
Bend the tube directly at the bend
It is possible to directly bend the electric pipe at the pipe bend, but it is not good. If the circuit is directly bent, it is easy to cause damage to the line and lead to an electric leakage accident.
Suggestion: Although it is not appropriate to bend the electric pipe directly, the elbow is also prohibited at the corner of the electric pipe. At the bend of the wire protection tube, the matching elbow tool or matching elbow should be used, and there should be no wrinkles. Increase the bend at the bend to buffer the bend pressure to reduce wear.
At the same time, it is not limited to follow the principle of horizontal and vertical, to use special Zhongcai PVC flame retardant wire and cable, the wire tube must be fixed in the wire groove, the lock box should be used when the wire box is connected to the wire tube, and the straight tube should be used every 80 cm One tube clamp, use a tube clamp every 20 cm around the corner.
Wu. Wire is buried directly without bushing
Error demonstration
Some irresponsible construction parties buried the wires directly into the wall during construction. The wires were not covered with insulated tubes, and the wire connectors were directly exposed. This would easily lead to hidden safety hazards. In future life, the wires are not protected and are easily damaged. The mouse bite or suffered external damage, which caused the wire to short-circuit.
Suggestion: The laying specifications of the wire are clear, the wire must be protected by an insulating sleeve, and the connector must not be exposed.
Everyone should keep these four principles in mind. When the hydropower is completed, take these four points for acceptance. Of course, if you can, it is naturally the most trouble-free to find a supervisor.
