Why should the second-hand house circuit be reformed? Renovation scheme of second-hand house circuit

In today's society, housing prices are soaring and time is tight, and more and more people choose to buy second-hand houses. However, second-hand houses have many disadvantages while saving owners time and money. Circuit aging is one of the important problems, so how to transform the circuit of second-hand houses? Next, I will bring you a second-hand house circuit transformation plan, hoping to help you.

Why should the second-hand house circuit be reformed?

1, the circuit has no grounding protection: when accepting the second-hand house, you can open several switch sockets to see if the wires have grounding protection. Grounding protection refers to a protective wiring method that the metal parts of electrical appliances that are not charged under normal circumstances but may be charged after the insulation material is damaged or under other circumstances are reliably connected with the grounding body with wires. Old houses with a long time generally have no grounding protection, which can not reduce the harm of leakage to people and property after circuit aging or short circuit. Therefore, effective grounding protection measures must be taken.

2. Simple wire loop: Old houses with long time such as sockets and lighting are often mixed with one loop. If several electrical appliances are connected at the same time, it is easy to cause the electrical box to trip, resulting in the unavailability of other electrical appliances. However, in the current wire loop design, high-power electrical appliances are all connected separately, and some will be connected by multiple complex loops.

3. Serious aging of circuit equipment: on the one hand, irregular construction is easy to cause aging of circuit equipment, on the other hand, with the passage of time, the equipment itself will inevitably age. Therefore, when accepting the second-hand houses that have been used for a long time, we must check whether the quality of the circuit accessories is good, and see if there are serious aging phenomena such as rust and damage.

4. Insufficient switch sockets: According to national standards, the number of fixed sockets in residential buildings should not be less than 12, but there are still many original sockets in second-hand houses that cannot meet this standard. However, if a large number of mobile sockets are used, when the current load increases, the mobile sockets will produce abnormal high temperature due to poor contact, which will bury the hidden dangers of electric shock and electrical fire accidents. Therefore, in the decoration of second-hand houses, it is necessary to pay attention to adding more switch sockets.

Second-hand house circuit transformation scheme:

1. Circuit transformation of second-hand houses with different service life: for commercial houses with service life of less than ten years, there is little difference between the strong and weak electricity of most houses and new houses, and the circuit transformation should be mainly based on local changes; For the second-hand house that has been used for 20 years, the circuit transformation mainly needs to optimize and adjust the original high-voltage system; For second-hand houses over 20 years old, the circuit transformation generally needs to remove all the original wires and carry out thorough rectification.

2. Renovation of second-hand housing trunking: Before the circuit renovation of second-hand housing, it is necessary to check the quality of the original trunking. If the conduit is damaged, the original conduit cannot be used. If the trunking is well preserved, the wires in the trunking can be directly replaced. This can save the cost of wire and tube.

3. Second-hand house wiring renovation: If the original circuit quality is no problem, then there is no need to dismantle it, but on this basis, some new lines and switch sockets are added to meet the more needs of the owners. However, it should be noted that the newly added power sockets and other circuits are best wired separately from the distribution box and cannot be wired at will. Avoid adding sockets and lamps to the original circuit, so as to avoid overloading a single circuit and causing tripping or even fire.

4. Pay attention to the grounding of the socket of the second-hand house: the original socket circuit of the old second-hand house may have no grounding wire, generally only two holes, which does not meet the safety standards for power sharing and must be replaced. One method is to replace the main power box and set the grounding in the power box; Another way is to consult the electricity management personnel of the property about the installation location and connection mode of the grounding wire, and never set the grounding wire privately.

5. Renovation of second-hand house weak current system: With the development of smart home, the transformation of second-hand house weak current may change more than strong current, and it often needs to be rewired. Before reconstruction, the layout of various weak current lines and the installation position of sockets should be considered in advance.

These are the reasons why the second-hand house circuits brought by Bian Xiao need to be rebuilt. The whole content of the second-hand house circuit transformation scheme.
