It is impossible to imagine the life of a modern person without electrical devices. Most people are accustomed to the fact that the house has lights on, clothes are washed in an automatic machine, coffee is brewed in an electric coffee maker in the morning, and food is cooked on the stove. All these wonderful appliances so essential for life are powered by electricity.
What happens if an ungrounded outlet is used?
From the school physics course, each person remembers that an electric current cannot arise from nowhere, it is the movement of charged particles in a conductor, which can serve as a wire. But many also remember, from the OBZh course, that electric current is dangerous to human life. When is there a danger of getting an electric shock? This happens if a person touches bare wires, or an appliance that is plugged into an ungrounded outlet. In their right mind, not a single adult will touch bare wires, but everyone can plug the kettle into an outlet without grounding.
In order for the "blow" to occur, an electrical circuit must be created. In the case when a socket without grounding is used, the current enters the device, accumulates in it and passes to the person as soon as he touches him. In this case, a person is a conductor, as he stands on the floor. The current passes through the body and then goes to the floor. At best, the victim will feel uncomfortable, and at worst, go to the hospital in an ambulance.
How to protect yourself from electric shock?
When there are many electrical appliances in the home, people do not always use only grounded outlets. In a hurry, they forget about the importance of grounding or do not know at all if it is in their apartment, and simply stick the plug into the outlet that is closer. Constantly using an outlet without grounding for the operation of a metal electrical device, there is a high risk that static voltage will accumulate in it and a person will receive an electric shock. To avoid this, you need to install an outlet with grounding contacts in every room at home. Of course, the risk will not disappear altogether, because it is impossible to be completely sure of the quality of the sockets, but it will still decrease.
Those people who have a large stove and a washing machine at home must additionally ground the appliances. It is quite simple to do this, you need to take a special wire, connect it to the device body and direct it to the ground. In private houses, this can be easily done, but in an apartment there may be problems with where to direct this ground wire.
Due to the fact that death from electric shock has long ceased to be a rarity, most developers, before putting a house into operation, equip the power grid with special protective shutdown devices. His job is that, in the event of a current leak, he disconnects the entire apartment from electricity, thereby saving residents from fatal injury. Today, it is the most effective protection against electric shock. Anyone can install such a system; for this, it is enough to contact the appropriate company.
