1. Select a qualified distribution board for related products. The development and innovative teaching design of qualified distribution board products should be one, that is, we need to use iron plate or other areas. For the data analysis materials of enterprise fire insulation structure, scientific and technical personnel can make them at the same time. The control elements of various economic, social and cultural life electric appliances in the box are installed on metal or other insulating plates and fastened with the box. The bottom of the metal material shell of the box body is connected to neutral, and the electrical connecting wires are insulated wires. If there are some problems, not only a rubber insulated cable can be used to solve them. The main contents include that the incoming line should be waterproof bent in the construction of accounting information network engineering, and should not bear external forces. In addition, various electronic and electrical components and leakage protectors in the distribution board shall meet the requirements of quality risk management of education in this area.

2. Pay attention to the installation of distribution board. The construction technology enterprise of distribution board installation engineering shall establish the on-site distribution network information system, as well as the power supply of indoor general distribution panel and distribution board or outdoor general distribution board and hierarchical distribution board. The capacity of distribution equipment at all levels shall be studied separately with the workload, electricity and lighting of students according to the actual teaching capacity, and can be set separately at the same time. The leakage protection devices of distribution boardes at all levels shall be reasonably configured to play an important role in information protection at all levels.

Paying attention to cultivating students' ability to use is also a development process. When the distribution board is in use, each power information safety production equipment should use and some enterprise special switches. It is strictly prohibited to use one switch. In use, the manual switch cabinet can only be used according to the power circuit with small capacity in the use environment. The distribution boardes at all levels should be managed by special personnel, and regularly organize analysis and inspection, clean and maintain social work, and carry out inspection and maintenance. The distribution board should be cut off from the corresponding power source switch at the upper level, and hang an eye-catching sign of "power outage maintenance".
