The basics of electrical safety. Top articles
This collection contains the best articles on the site bgv.electricianexp.com on electrical and fire safety in the operation of electrical appliances and wiring in the home.
Electric current is life threatening! Moreover, his main danger is that he does not see and do not hear. The degree of its influence depends on many factors: on the type and magnitude of the voltage and current, the frequency of the electric current, the path of the current through the human body, the duration of the electric current on the human body, environmental conditions.
A person begins to feel an alternating current of industrial frequency at 0.6 - 15 mA. Current 12 - 15 mA causes severe pain in the fingers and hands. At a current of 50 - 80 mA, respiratory paralysis occurs, and at 90 - 100 mA, paralysis of the heart and death occurs. It must be remembered that the human body is not affected by stress, but by the magnitude of the current. Under adverse conditions, even low voltages (30 - 40 V) can be life threatening!
In order for as few as possible cases of electric shock to people to occur in everyday life, it is necessary to make the electrical safety rules known and understandable to everyone. I would be glad if the proposed selection of articles will help to clearly understand the seriousness and mandatory necessity of electrical safety measures, as well as to learn how to safely use electric energy in everyday life and to understand what caused these or other electrical safety requirements.
A basic article on the basics of electrical safety. It provides specific and simple rules that must be observed when using electricity in everyday life in order to avoid electric shock.
How to protect children from electric shock
Electricity brings many benefits to man. But it is dangerous, especially for children. The article describes the main measures to protect children from electric shock.
Electricity and electrical safety: educational program for beginners electricians
Sometimes electricity from a good helper can turn into an evil enemy, from creative energy to destructive, and sometimes even deadly. The article describes the danger of electricity, the properties of various current sources, and what rules must be followed when performing various electrical work.
Resistance of the human body - what it depends on and how it can change
The resistance of the human body is by no means constant; its value depends on many factors: on the state of the person at the moment of contact (mental and physical), on the parameters of the closed circuit, on the external environmental conditions in which the person is at the time of the impact.
In cases where a person is exposed to electric current, emergency action is necessary. This article describes what these actions are and how to perform them.
About electric injuries and how to deal with it
The article discusses the basics of electrical safety and the problems of domestic electrical injuries, describes preventive measures due to which household injuries can and should be completely eliminated.
Step voltage and potential equalization
A bare tattered wire that has fallen to the ground is very dangerous. But what kind of phenomenon is it, thanks to which a wire that lies “innocently” lying to one side becomes a deadly threat?
Appointment and principle of action of protective grounding. Protective grounding plays a huge role in ensuring the electrical safety of your home, and you should pay maximum attention to the quality and accuracy of its implementation.
About grounding and grounding for "dummies"
Grounding rules, what distinguishes "grounding" from "grounding", what is a ground loop and what is it for, what is required for wiring a ground wire around the house.
Power supply and bathroom lighting
The bathroom, in terms of the possibility of electric shock, is a hazardous area. A higher hazard implies a greater responsibility and requires us to take additional safety measures when installing and installing the bathroom wiring.
About the main and additional potential equalization systems and their functional purpose.
Protection against leakage currents: RCD and difavtomat
Why do I need an RCD and a difavtomat? What is the general principle of their work? What is the difference?
What you need to know when installing an RCD and grounding device in an apartment or private house
Why it is impossible to use RCDs or electronically controlled difavtomats, do home-made grounding and connect the grounding terminals of sockets and electrical appliances to them. Why it is impossible to connect the ground terminals of sockets and the neutral wire of the electrical wiring, to independently re-ground the neutral wire at the input and, accordingly, the zeroing of electrical appliances. For all contentious issues specific examples are provided.
RCD in two-wire: to put or not to put?
There are many opponents and supporters of the installation of RCDs in the power system TN-C (in the absence of a zero protective wire in the apartment). The article is interesting by the presence of 52 (!) Comments on the stated issue. As a result of heated discussions, the majority of those noted in the comments decided that RCDs must be installed even in two-wire for the purpose of electrical safety.
Connection of an electric stove and a washing machine in the TN-C system
The TN-C electrical grounding system has long been outlawed and banned for use. But it is easy to ban, but what about those whose homes were commissioned long before the introduction of new norms and rules?
Broken common neutral wire in the access electrical panel: danger of overvoltage
Why can a broken common ground wire in the access electrical panel cause an increase in the mains voltage? How is this dangerous? How to avoid this?
What is soldering? Soldering Safety
Soldering is one of the most popular activities of people professionally associated with electrical engineering and electronics. This article provides electrical safety rules for soldering and useful tips on how not to spoil your health by inhaling a pair of lead and tin.
