Distribution boards | Types of Boards

 In an electrical installation, a distribution board is the main part. In general terms, the boards are cabinets that contain the connection, maneuver, command, measurement, protection, alarm and signaling devices that fulfill a specific function within an electrical system. Its main function is to protect each of the different circuits in which the installation is divided. They must also withstand short-circuit current levels.

To design a switchgear, certain considerations must be taken into account: whether it is for low or medium voltage and standards, to guarantee the continuity and protection of the switchgear and its operators. Several factors and variables must be taken into account before installing and designing a switchboard: Power to handle, Device Control System, Maintenance Policy, Safety of the facilities that will control and of the operators.

They must also undergo certain tests to check their functionality and effectiveness: Dielectric tests, thermal tests, short-circuit tests, degree of protection, mechanical maneuvers.

There are several types of boards, depending on their location:

Main distribution board: It is connected to the main power line and the circuits are derived from its Secondary distribution boards: They are powered by the main one, auxiliary in the protection and operation of sub- feeders

Step boards: Their purpose is to protect the derivations, which due to their feeder or subfeeder capacity, cannot be directly connected

Command boards: They contain safety and maneuver devices.

What is an electrical overload and how to avoid it?

Image
 An electrical overload is a flow of current in excess of the usual operating electrical load. It can also be defined as an excess charge that passes through conductors and circuits. Therefore, the power required by several devices connected at the same time in the same circuit can exceed the capacity of the system. There are two types of overloads: transient (lasting for milliseconds) and continuous (due to a bad installation). In addition, it must be taken into account that the connections may have different models and sizes of circuit breakers, cables and plugs. Next, we tell you everything you need to know about electrical surges, how to avoid them and how to solve them. How to know if there is an electrical overload Whether at home or in the workplace, a power surge can affect specific connections or the entire system, however, watch out for similar indicators in both forms? Some clear signs that there is an overload are: Lights starting to dim If you notice the lighti...

Why Circuit Breakers are Critical for Motor Protection and Control

Image
 Circuit breakers are a critical component of any electrical system, and they play a particularly important role in protecting and controlling motors. Motors are often used in industrial and commercial applications, and they can be expensive and difficult to replace if they are damaged or fail. Here's why circuit breakers are so important for motor protection and control: Overload Protection One of the primary functions of a circuit breaker is to protect electrical circuits from overloading. When a motor is running, it draws a certain amount of current from the electrical supply. If the current exceeds the rated capacity of the motor, it can cause overheating and damage. A circuit breaker can detect when the current exceeds a certain level and interrupt the circuit, preventing damage to the motor. Short Circuit Protection Another important function of a circuit breaker is to protect against short circuits. A short circuit occurs when an electrical current flows throug...
