BUILDING THE PRACTICE MODEL OF POWER SUPPLY FOR AN APARTMENT
Abstract. It can be seen that the more modern life is indispensable to the presence of electrical and electronic devices. These devices are ubiquitous and serve all human interests, from living to production. Therefore, Electrical Engineering (Electrical and Electronic Engineering) is always an important discipline in the field of engineering. In this report, we introduce our study on the construction of a practical power supply model for an apartment. The research results are used to develop practical exercises for the "Power supply practice", to serve the training and improvement the quality of practice for students; To help students access to reality as well as improve suitable skills that the recruitment market demands.
Keywords: Power supply, Electrical system for buildings, civil electric circuits.

simulate apartments in reality, thus not ensuring the visual properties.
In order to overcome this, we have carried out research and built a practical model of power supply for an apartment. This model is built in accordance with the design drawings to supply enough electricity for an apartment, with the size being wide enough for easy operation and installation of electrial wires thus ensuring the visual properties. In particular, this apartment model is constructed from small blocks so we can practice electricity supply with many different apartment models.
2. Fabrication and practice on power supply practice models
2.1. Power supply premises for apartments
We manufacture the power supply practice set as follows:
Figure 1 Describes the premises of the apartment and designs the power supply for the apartment. The apartment has an area of 80 m2, including: 02 bedrooms, 01 living room, 01 kitchen, and 02 bathrooms. Power supply requirements are as follows: power supply for lighting, sockets, water heater, air conditioning, etc.

In addition, there are paired models to link blocks (Figure 8), small blocks of 200 mm x 54 mm fitted with right angles (Figure 9), small blocks of200 mm x x 54 mm fitted with T-shaped blocks (Figure 10).

2.3. Installation of the apartment model
Apartment installed from small blocks (Figure 11, Figure 12, Figure 13) consist of three floors; to install the apartment, we install each apartment floor one by one (Figure 14). The height of the apartment after installation is 600 mm. With this height, students can easily move inside the apartment to perform the installation of electrical systems for the apartment.

3. Conclusions
We have successfully built practical power supply models for apartments. This practical model helps students to install and run an electrical system for an apartment well and thorougly as in practice. With models made up of small blocks, we can install different models of apartments every year for students to practice. Experiments show that through practice on this model, students will be more confident in installing electrical systems for actual apartments.
