How much do you know about decoration weak electricity and strong electricity construction?

  The power distribution box at home is generally pre-installed by developers behind the door, and it is not suitable to change the location by yourself. But pay attention to whether a protective device (air switch, also called a circuit breaker) is installed. In this way, when a short circuit or overload occurs, it can automatically trip to prevent leakage accidents. The size of the air switch in the distribution box cannot be too large, otherwise it will not trip when there is a circuit problem. For some high-power electrical appliances, a separate circuit must be pulled. Do not connect N electrical appliances to one circuit in order to save money, which will easily cause overload. Once the line is overloaded, the wires inside are easy to heat up, causing short circuits or electrical fires, and the consequences are disastrous! There is no need to destroy the results of your hard work because of a small wire. When distributing circuits, it is generally divided into several circuits according to different functions: lighting, ordinary power sockets, air conditioner power sockets, and power sockets in the kitchen and bathroom should all be set up with separate circuits.
  The editor of Beilein thinks that it is necessary to clearly understand the current diameter of the entrance line before decoration. Now most developers will install the entrance line of 6mm2-10mm2, and the entrance line must not be less than 6mm2. Then, based on the appliances in your home, estimate the total electricity usage. As for wires, go to a large building materials supermarket to buy them. There are discounts if you buy more, and the price is not much different from the ones outside.
