An electrician is a skilled worker who performs plumbing work during the operation and repair of electrical structures and equipment. If we talk in simple language, then the electrician is responsible for supplying electricity and connecting the equipment to the electrical network. But an electrician is a person who is responsible for replacing faulty parts, voltage regulation and so on.

The profession of a modern electrician is a variety of narrow specialties, each of which is designed to work with one or another type of equipment:

Electrician for the repair and operation of explosion-proof electrical equipment.
Electrical mechanic for repairing equipment of power stations.
Electrician for repair and maintenance of switchgear equipment.
Electrician for rolling stock repair.
Electrical mechanic for repairing electrical machines - overhead cranes, electric motors, and so on.

The list of narrow specializations of an electrician can go on for a long time. However, the main thing to understand is what responsibilities fall within his scope of activity. And this is exactly what we will talk about next.

About responsibilities and personal traits

So, an electrician has a number of responsibilities that do not depend in any way on the specialization of this profession. These are the following:

ensuring the operability of electrical equipment;
regular inspection of mechanisms to identify any malfunctions;
performing preventive maintenance in accordance with production instructions;
informing management that it is necessary to purchase certain spare parts, and so on.

From all this we can draw a logical conclusion that the durability and serviceability of the equipment depends on the electrician. Therefore, people of this profession have always been distinguished by extreme responsibility, observation and diligence. And considering that we're talking about about working with electrical equipment, then the following will be very useful for such an employee: personal qualities, such as accuracy, resistance to stress, patience, attentiveness, pedantry. He should have well-developed fine motor skills, and an accurate eye and excellent hearing are also welcome, as well as long-term memory with the ability to distribute attention.

About the advantages and disadvantages

An electrician is a specialization that has a lot of important advantages. All because this profession- it's two in one. Firstly, a real master will be able to carry out both ordinary plumbing work and simple electrical installation work without any problems. Secondly, this profession falls into the well-paid category. And if you consider that in addition to the main job, such a master can also count on receiving additional income, then the attractiveness of the profession doubles. Thirdly, electrical engineering today is developing very rapidly, so the professionalism and overall development of the employee increases significantly.

If we talk about the disadvantages of the profession, they consist in an increased risk to human health, which is also typical for an ordinary electrician. In addition, the working conditions of an electrician cannot be called simple - and this is also a significant drawback. Often such workers come into contact with lubricants or moving heavy equipment. The latter can lead to the development of problems with the musculoskeletal system. And increased background noise can cause hearing problems and emotional fatigue.
