The selection of wires needs to pay attention to the requirements of the national standard, the DC resistance of the conductor fully conforms to the national standard, has good conductivity, high safety, and the length meets the requirements of 100 metersStandard requirements: The products produced by the regular manufacturers that have passed the quality pass should be affixed with the certification mark in a prominent position of the product, that is, the "CCC" mark and the inspection report of the quality supervision department are made of environmentally friendly high-quality materials, which feel soft and flexible, and release a small amount of water vapor-like translucent white smoke when forced to burn, which does not affect survival and rescue.
The selection of high-quality raw materials, qualified products, in the purchase of raw materials, production equipment, production technology and other aspects of strict control. Therefore, the appearance of the wire and cable products produced is smooth and round, and the color is uniform.

1. Go underground.
Advantages: the material and labor costs that need to be consumed are less, the above-ground construction is more convenient than others, the construction difficulty is not large, the construction period is shortened, and the vast majority of hydropower masters are proficient.
Disadvantages: Buried underground water pipe joint leakage will soak bricks, not easy to detect, but also wait until the leakage downstairs, downstairs to find something. If you meet a bad neighbor, it's enough for you, and if other people's furniture is more expensive.
Let's not talk about maintenance, compensation must be given, who let you not do a good job of water and electricity! To repair, you must pry up the bricks or floors, which is likely to cause serious losses and even affect the neighborhood relationship downstairs.
2. Go to the sky.
Advantages: Once there is a problem, it can be detected in time, such as water leakage is drip in your own space at most, and the water pipes are generally distributed in the kitchen and bathroom space, all of which are made of suspended ceilings, and maintenance is more convenient!
Disadvantages: Aerial work has high technical requirements for the master, and the cost of materials and labor will be more than that of walking on the ground.

Bathroom: All wires are on top, and the pipe of the wires is higher than the water.
Other places: the light line goes to the top, and the socket panel line goes to the ground; If the socket panel is not far away, go to the wall.
In addition: 1. It is recommended that special electrical appliances such as air conditioners, refrigerators, and water heaters need to be separately drawn from the electric switch box to the location where the electrical equipment is installed, and the wires are generally 4 square meters.
2. There are many electrical equipment in the kitchen, and the socket panel is recommended to be 4 square meters.
3. Other (living room, bedroom, balcony, etc.) socket panels are generally more than 2 square meters. If there are many household appliances, you can consider 4 square meters, if it is not much, the square can basically meet the demand.
4. The lighting wires are generally square and above. Although the heating of the bathroom (lamp heating, air heating) can also meet the needs, it is recommended to use 2 square meters.
5. It is recommended that all socket panels wear 3 wires: live wire, neutral wire, and ground wire. The switch panel of the lamp has 2 wires, the live wire and the neutral wire. Switches and sockets have panels, and the number of wires refers to the socket panel.

Yes, some circuits have specific routing area requirements.

Generally do protection go underground.
1. The current structure houses are mostly reinforced concrete, and the line pipe used in modern times is not the previous metal line pipe, the load-bearing force is limited, and the slotting on the wall is easy to damage the steel structure and cause cracking.
2. In addition, the slotting of reinforced concrete walls is laborious and laborious. Nowadays, the process is generally on the ground, and many of them are directly installed with open pipes and then covered (such as laying cement and laying floors).
3. According to the current quality requirements, the distance of the line is as short as possible and easy to twitch, so that it can be overhauled and replaced in the future. And walking on the wall must go around in circles. The fee line is also stuck.

Personally, I think.
The hall and room go underground (there is not much chance of dampness).
Toilets, kitchens walk on the wall or above the ceiling (now the general toilet and kitchen will be equipped with ceilings, gusset kind), and the gusset is easy to disassemble, and individuals can also easily disassemble it for maintenance. It is also not easy to get wet.
It's better that way.
If all go to the wall.
1. When the layout of the house is changed in the future. Because your line is in the wall. Suppose you want to tear down the wall. It's a bit of a hassle to redo it.
2. If the decorator hits the stressed wall. You've seen anyone who has installed dark lines. Cut the wall horizontally. (To use an analogy) is equivalent to not being straight. People are naturally unstable on their feet, and I personally feel a little dangerous.
I'm having to change it right now.
Hope the above is helpful to you.

It should be laid along the wall or along the inside of the ceiling.
In home decoration, the wires that wear protective pipes should not be laid under or on the ground. It is also not advisable to lay along the ground.
-
It should be concealed along the ground, and along the wall, the decoration company does it in order to save materials and reduce the difficulty of construction. Concealment of the wall will destroy the thread when the hole is made. According to the building construction specifications, the electrical pipelines on the wall must be laid vertically, and those who lay horizontally on the wall are illegal operations.

It is best not to go underground, it is easy to short circuit when wet.
Hydropower totals about 7000, including the cost of slotting and the cost of water pipes and wires. >>>More
There are generally large onesRenovation companyand the wire will goceilings, which costs more; Secondly, the walls do not advocate horizontal grooves of more than 30 cm; It is common practice to wiring the floor with electrical wiring, but toilets and kitchens are suitable for the top. The ground humidity is too heavy and easy to break; Once the line buried in the ground is broken, if it is to be repaired, it is necessary to dig porcelain. For materials and labor, taking the ground wire can save some materials and facilitate construction; However, considering factors such as later maintenance, the ground is not suitable for walking wires. >>>More
