Electric panel - fuse - circuit breaker

In any electrical system, safety is essential to protect people and equipment from fire and electrocution risks. Electrical arrays, fuses and circuit breakers play an essential role in the protection and distribution of electricity. In this article, we will explore in detail these key elements of electrical safety, explaining their operation, their importance and the precautions to be taken to ensure a safe and reliable electrical system.

Electrical table: Electrical distribution center

The electric table, also known as the distribution table, is the central point of distribution of electricity in a building or installation. It receives the main power supply and then distributes it to the various electrical circuits of the structure.

The electric table consists of various elements, such as circuit breakers, fuses, differential switches and connection bars. It is designed to allow effective control of the power supply, as well as to ensure protection against overloads and short circuit breaks.

Fusible: Protection against electrical overloads

The fuses are safety devices that protect electrical circuits from power overloads. They are usually composed of a driving filament that melts when an excessive current crosses the circuit. This fusion cuts the electrical circuit, thus protecting wires and connected devices.

The fuses must be properly dimensioned for the circuit they protect. They are usually classified according to their current capacity (ampers) and their maximum voltage. In case of overload or short-circuit, the fuse melts, which requires its replacement to restore the electrical circuit.

Circuit breaker: Multi-purpose protection

Circuit breakers are more advanced electrical protection devices than fuses. They work by detecting power overloads and short circuit, then opening the circuit to cut off protective devices are crucial to maintaining a safe and reliable electrical system. Whether it's an electric board, a fuse or a circuit breaker, everyone plays an essential role in the prevention of overloads, short circuit breaks and the risks of electric fire.

It is important to understand the operation of each element and to use it properly to ensure optimal safety. Electrical tables are used as a power distribution centre, distributing power to the various circuits. They are equipped with fuses or circuit breakers to protect circuits from overloads and short circuit breakers.

The fuses are traditional safety devices that use a driving filament to melt in case of power overload. When this happens, the circuit is interrupted, thus preventing damage to wires and devices. The fuses must be properly dimensioned to match the circuit capacity they protect.

The circuit breakers offer more advanced and versatile protection. They detect overloads and short circuit using internal mechanisms such as magnetic and thermal switches. When an excessive current is detected, the circuit breaker automatically triggers to interrupt the circuit. After the trigger, it can be manually adjusted once the problem is solved.

One of the advantages of circuit breakers compared to fuses is their ability to be rearmed after a trigger, making them more practical and economic in the long term. In addition, some circuit breakers offer additional features, such as the detection of current leaks with differential switches, which provide additional protection against electrocution risks.

It is essential to follow good safety practices when installing and using these protective devices. Here are some important tips:

·        Hire a qualified electrician for the installation and maintenance of the electric board. This ensures a correct installation and complies with safety standards.

·        Clearly label the circuits in the electric table to facilitate the identification of circuit breakers or matching fuses.

·        Do not overload electrical circuits by connecting too many devices or using multiple extensions. Pay attention to electric loads between available circuits.

·        If the circuit breaker or fuse is triggered, search for the cause of the incident before rearming or replacing the device. It is important to identify and solve any underlying electrical problems.

·        Regularly perform visual checks of electric boards to ensure that there are no denuded wires, loose connections or signs of overheating.

Electrical table, fuse and circuit breaker: essential elements of electrical safety

In conclusion, electrical arrays, fuses and circuit breakers are essential elements of electrical safety. They protect the circuits from overloads and short circuitry, thus minimizing the risk of fire and electrocution. By understanding their operation and respecting good safety practices, we can ensure a safe and reliable electrical environment for our daily needs.
