Design of Low voltage Electrical Panel Boards

The design of low voltage electrical panel boards is a critical aspect of electrical system engineering, as it plays a pivotal role in distributing electrical power safely and efficiently within a facility or industrial setting. To create an effective panel board design, several key considerations must be taken into account. Firstly, understanding the specific requirements of the electrical system is paramount. This involves comprehending the load demands, including current, voltage, and frequency requirements. These requirements will serve as the foundation for the entire design process.

Next, selecting the appropriate type of panel board is essential. Options range from distribution panels for general power distribution to motor control centers (MCC) for managing motors and control circuits. The choice depends on the application's unique needs. Calculating load distribution is the core of the design process. Determining the total load and allocating it to individual circuits based on load characteristics and safety codes ensures an even distribution of power while considering potential future expansion. To safeguard the system and its components, circuit protection devices, such as circuit breakers and fuses, must be carefully chosen. Their selection should align with the load requirements and short-circuit current ratings (SCCR) to maintain safety and compliance with local electrical codes.
