The Basics of Electricians. Teaching for an electrician. What an electrician should know

The modern world is difficult to imagine without machines andmechanisms that work with electricity. Improved and the quality of his presentation. For example, aluminum wires are replaced by copper ones, non-combustible insulation is invented. Production facilities were divided into zones on the principle of fire safety. The idea is simple: a fire that has arisen in one zone can not pass into another. With the same speed, there is a growing need for skilled, up-to-date specialists. What should an electrician know?

Who is an electrician?

A specialist who has received a special education andworking in the field of electronics, is called an electrician. That is, it is an employee who knows the basics of electrical engineering, the main occupation of which is the installation, repair and operation of electrical equipment. Repair and installation work can be carried out not only indoors, but also on the street, including at height. In addition to basic skills, an electrician can always provide first aid to a victim of electric shock.

The main task of an electrician is the organization of uninterrupted operation of electrical systems. As in production or residential premises, and on the streets or in production processes.

The main professional qualities of an electrician are accuracy, responsibility, vigilance, caution, attentiveness and concentration.

Professional Responsibilities

This profession in our country is quite common, and job descriptions are formed quite clearly:

• conducting wiring or power cables;
• connection of electrical equipment with preliminary calculation of cables;
• drawing up a plan for the electrification of industrial or residential premises;
• installation of new electrical networks, repair and dismantling of failed, etc.

The studied fundamentals of electricians enablespecialist install control or protection devices, insulators, deal with marking out points of equipment installation, troubleshooting for short circuits, laying cable channels. And also to measure the resistance of insulating materials, to carry out preparatory work before the first switching on of mechanisms, to mount and dismantle alarm or protection systems, to connect wires, cables, couplings, etc.

Basics of Electricians

The work of an electrician involves a large amount of knowledge. Elementary course: "Electrician for beginners" provides an opportunity to study:

• basic concepts and quantities used in electrical engineering;
• conventional symbols used in electrical circuits;
• materials and their electrical conductivity;
• marking of cables, electrical circuits and wires;
• methods of calculating the cross-section of cables and wires;
• methods of obtaining contacts and other compounds;
• rules for the installation of a system of grounding and protection of electrical installations;
• ways of connecting generators and motors;
• the order of protection against overloads of electric schemes;
• existing types of wiring and how to install it;
• basic safety precautions when conducting work on electrical wiring;
• rules for the provision of first aid in case of electric shock.

So, what is necessary to know the beginneran electrician? The basics of electricity are the main base of the future electrician. But in addition, it is necessary to have a good command of the basics of applied mechanics, automatics and electrical engineering.

Required level of knowledge

Basics of electricians - this is the minimum that is necessary for the work of an electrician. Here are a few categories, to have information about which a modern electrician is obligated.

1. Direct purpose of the device or mechanism that needs repair.
2. Frequent problems with a particular device.
3. Rules for the operation of a non-functioning mechanism or device,
4. Fundamentals of safety in the conduct of electrical work.

If there is a need to repair the wiring, the electrician must know and present in detail its circuit, and be able to diagnose the causes of failure.

Skills

Training for an electrician provides the necessarywork receptions. The specialist learns to read circuit diagrams and wiring diagrams, calculate the wire cross-section, work with measuring devices, independently collect simple electrical circuits, conduct assembly of contact connections by soldering or twisting.

The main tool

The necessary equipment for electrician work is divided into four categories:

• hand tool;
• the electrotool;
• measuring instruments;
• consumables and accessories.

A set of hand tools is different forevery electrician. But there is a necessary base. After training for an electrician, a young specialist will be familiarized with how to work with pliers (pliers), an assembly or universal knife, a set of screwdrivers and wrenches, a hammer, a chisel, a construction tape measure, a stripper and an electric soldering iron.

If the production of electrical installation works requiresmore serious intervention, it will be necessary to have a perforator with a transition cartridge and a set of nozzles, a bolt for cutting steel corners for a grounding system or laying a rod for cables. Also need an electric drill, which, if necessary, can work as a screwdriver.

As follows from the course "Electricians for Beginners"measuring instruments today perform many functions and in the work they are needed. One of the main ones is a probe of the presence of a phase in the electrical network. It looks like a screwdriver, but the case is not strong, because the device has a different purpose. More information can be read from a universal multimeter. In addition to basic measurements, it is able to verify the correctness of installed equipment or paved networks. Current clamps allow you to connect without disrupting the network and make measurements.

Auxiliary devices are not included in thea list of mandatory, but greatly facilitate the work of a specialist. This can be a stepladder, a carry, an autonomous light source, markers, building pencils, levels, calipers, etc.
