Modern world is hard to imagine without machines and mechanisms powered by electricity. The quality of its delivery is also improving. For example, aluminum conductors were replaced with copper ones, non-combustible insulation was invented. Production facilities began to be divided into zones according to the principle of fire safety. The idea is simple: a fire that has arisen in one zone cannot move to another. The need for qualified specialists who keep up with the times is growing at the same rate. What should an electrician know?
Who is an electrician?
A specialist who has received a special education and works in the field of electronics is called an electrician. That is, this is an employee who knows the basics of electricians, whose main occupation is the installation, repair and operation of electrical equipment. Repair and installation work can be carried out not only indoors, but also outdoors, 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 to organize the uninterrupted operation of electrical networks. How inindustrial or residential premises, and on the streets or in industrial processes.
The main professional qualities of an electrician are accuracy, responsibility, vigilance, caution, attentiveness and concentration.
Professional responsibilities
This profession is quite common in our country, and job descriptions are formed quite clearly:
- 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 ones, etc.
The studied basics of electricians enable a specialist to install control or protection devices, insulators, mark equipment installation points, troubleshoot short circuits, and lay cable channels. And also measure the resistance of insulating materials, carry out preparatory work before turning on the mechanisms for the first time, install and dismantle alarm or protection systems, connect wires, cables, couplings, etc.
Electrical Basics
The work of an electrician involves a large amount of knowledge. Elementary Course: "Electrics for Beginners" provides an opportunity to learn:
- basic concepts and quantities used in electrics;
- symbols used in electrical circuits;
- materials and their electrical conductivity;
- marking cables, electrical circuits and wires;
- methods for calculating the cross section of cables and wires;
- methods for getting contacts and other connections;
- rules for the installation of a grounding system and protection of electrical installations;
- connection methods for generators and motors;
- order of electrical circuit overload protection;
- existing types of wiring and how to lay it;
- basic safety precautions for electrical work;
- rules for first aid in case of electric shock.
So, what does a beginner electrician need to know? The basics of electricity are the main base of the future electrician. But besides this, it is necessary to have a good command of the basics of applied mechanics, automation and electrical engineering.
Required level of knowledge
Electrical basics - this is the bare minimum that an electrician needs to work. Here are a few categories that the modern electrician must be aware of.
- Direct appointment of a device or mechanism that needs repair.
- Common device-specific problems.
- Rules for operating a non-working mechanism or device,
- Basic safety precautions for electrical work.
If it becomes necessary to repair the wiring, the electrician must know and present in detail its circuit, as well as be able to diagnose the causes of failure.
Skills
Training onelectrician instills the necessary work techniques. A specialist learns to read circuit diagrams and wiring diagrams, calculate the cross-section of wires, work with measuring instruments, independently assemble simple electrical circuits, and solder or twist the assembly of contact connections.
Main tool
The necessary equipment for the work of an electrician is divided into four categories:
- hand tool;
- power tool;
- measuring instruments;
- Consumables and accessories.
The set of hand tools is individual for each electrician. But there is a necessary base. Having completed training as an electrician, a young specialist will be familiarized with how to work with pliers (nippers), a mounting or utility 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 work requires more serious intervention, then you will definitely need a puncher with an adapter cartridge and a set of nozzles, a grinder for cutting steel corners for a grounding system or laying a strobe under cables. You will 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 they are necessary in work. One of the main ones is a probe for the presence of a phase in the electrical network. Looks like a screwdriver, but the body is not durable,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 check the correctness of installed equipment or laid networks. Current clamps allow you to connect without interrupting the network and take measurements.
Auxiliary devices are not included in the list of mandatory, but greatly facilitate the work of a specialist. It can be a stepladder, a carrier, an autonomous light source, markers, construction pencils, levels, calipers, etc.
