A life without electricity is unthinkable. Today, transportation, traffic, workplaces, health, communication, press, security systems, energy production, water distribution, maintenance and repair work, such as counting is not possible in all areas of life, depending on electricity continues. No matter how short a power outage is, it is enough for life to be paralyzed. Transport systems stop, traffic signals do not work, subways do not work, elevators and escalators can not be used, computers can not work, people can not go to work, shopping can not be done, banking systems stop, factories stop, nothing can be done briefly. However, the use of electricity is risky.

Electricity is used in this way with electric current. Electrons are what make up the electric current. Electricity is generated by the movement of negatively charged electrons. This movement is from the negative direction to the positive direction. The amount of electrons or electrical charge passing through a conductor per unit time is called current.

The number of electrons in their atoms is different depending on the type of metal. The number of electrons in the atoms of the conductive substances is less than four, and the atoms release them because they cannot complete them in eight. Therefore, the number of sebestant electrons in conductive materials is millions. When these conductive materials are electrified, electrons are activated and electric current is generated.

The difference between electrons and protons at any point in the conductor means potential. The potential difference between any two points of the conductor is voltage. Electrical networks differ according to the voltage types as follows: low voltage, high voltage and very high voltage. Low voltage is the voltage whose active value is below 1000 Volts or 1000 Volts.

The Low Voltage Directive (LVD), 2014 / 2014 / EU, which was finalized in the year 35, has been issued with regard to the safety of electric vehicles in homes and businesses in European Union countries. In our country, the Regulation on Electrical Equipment Designed for Specific Voltage Limits (2014 / 35 / EU) has been issued based on this directive.

This regulation not only ensures the functioning of the market, but also describes the requirements for protecting the health and safety of electrical appliances, people, pets and goods on the market.

Essentially, the scope of the regulation includes electrical devices designed and manufactured for use with 50 Volts and 1000 Volts for alternating current, and 75 Volts and 1500 Volts for direct current.
