Recommended books for the introduction of electricians

According to work experience, engaged in electrician operations, the most basic professional knowledge is the study of the "Fundamentals of Electrical Technology" book, I have contacted a number of versions, the content is basically similar, "Fundamentals of Electrical Technology" introduces the basic theory of electricity, on the general circuit are involved in the electric motor, relay contact system, electrical safety and so on have been introduced.

If you just want to learn about electricity for everyday life, consider buying books like Home Electrician, and books like Home Appliance Repair. Maintenance electrician primary and intermediate on the daily life of the circuit is also introduced to cover, the junior worker's books are usually illustrated, for beginners, easier to get started.

If you want to have an in-depth understanding of electricity, then you need to learn more things, such as, basic electronics, power electronics digital and analog circuits, electrical control and PLC, microcontroller, C language, automatic control principles, HMI, microcomputer principles, and so on a variety of courses, and the need to have a basic foundation in advanced mathematics.

Expansion:

Electrotechnics:

The scientific and technical study of the objective laws of the electromagnetic field and their applications, as well as the two major industrial production systems of electric power production and electrical manufacturing.

Electrician general knowledge:

Before decorating must have (strong electricity, weak electricity) construction plans, completion of the completion of the electrical project to provide as-built drawings.

Electrical installation construction personnel should be licensed.

Wiring should be color-coded, phase line (L) color should be uniform, zero line (N) should be black, protection line (PE) must be yellow and green.

Plastic wire protection tube and junction box appearance should not be damaged and deformed.

The piping is generally 4-point pipe (DN15), 6-point pipe (DN20), light pipe wall thickness of 2 .0 ± 0.3mm, no more than 4 threading.

Ordinary appliances with 2.5mm2 copper wire. Air conditioning and other high-power appliances need to be equipped with 4mm2 or 6mm2 copper wire.

Strong and weak circuits are prohibited in the same set of tubes.

The same indoor power, telephone, TV and other sockets should be on the same level elevation, the height difference should be less than 5mm.

In the installation of lamps and lanterns, the lamps and lanterns designed to install the fixed point of the whole fixed.

Ceiling set up in the distribution box: where the need for wires, wiring parts, are required to set up the distribution box. And shall not be fixed on the wooden keel, should be fixed on the top.

When the downlight installation needs to be opened, the main attached keel position should be verified to avoid cutting and damaging the keel.

Lighting fixtures should be installed separately with separate switches, and each lighting circuit should not exceed 2KW (excluding lanterns), and combined fixtures can be controlled in groups.

Ordinary chandelier using soft wire itself to do the hanging body. Only for lamps and lanterns with a mass of less than 1kg. more than 1kg of lamps and lanterns must use a hanging chain, and the soft wire is not subject to force.

Should be based on the location of electrical equipment to determine the direction of the pipeline, elevation and the location of switches, sockets line positioning after grooving.

The depth of the wall (floor) groove in the premise of not destroying the stressed steel, to ensure that the concealed pipeline oiler repair is not exposed.

When the length of the pipeline exceeds 15 m or there are two right-angle bends, additional pull boxes should be installed.
