MCB (Miniature Circuit Breaker) is an automatically operated electrical switch that protects circuits from overcurrent and short circuits. It is mainly used in low-voltage applications such as residential, commercial, and light industrial installations. Working Principle of MCB: Applications of MCB:… Continue Reading →
Electrical drawings play a crucial role in the design, installation, and maintenance of electrical systems. They provide a standardized way to communicate electrical configurations, ensuring safety, compliance, and efficiency. To achieve these objectives, electrical drawings must adhere to established regulations… Continue Reading →
When it comes to electrical panels, every component plays a vital role in ensuring functionality and organization. One such often-overlooked feature is the drawing pocket. This small yet essential element keeps crucial documentation accessible and secure, making it a must-have… Continue Reading →
In simple terms, when we set up an electrical system, we use three wires: the “line” (or “phase”), the “earth,” and the “neutral.” These wires have specific jobs in making electricity work safely. The main differences between the Earth (Ground)… Continue Reading →
In the context of an electrical panel or distribution board, ducts generally refer to channels or enclosures designed to house and organize electrical wires and cables. These ducts are also known as cable ducts, wireways, or cable trays. They are… Continue Reading →
Dynamic braking resistors are electrical devices used in braking systems to dissipate the excess energy generated by electric motors or generators during the braking process. When an electric motor or generator is decelerating or braking, it acts as a generator,… Continue Reading →
Fan and filter In an electrical control panel, a fan is a device used for ventilation and air circulation. It consists of a motor and fan blades rotating to draw air into the panel and expel hot air. On the… Continue Reading →
In AutoCAD Electrical, the “Reference Only” arrow is a symbol that represents a non-physical or informational connection between different parts of a wiring diagram or circuit diagram. By using the “Reference Only” arrow, AutoCAD Electrical allows designers and engineers to… Continue Reading →
Sometimes we have multicore cable and we want to show source and destination markers on the individual wires of a cable, but we want to show the wires coming together to form the cable. So at that time we have… Continue Reading →
We use the source and destination arrows to identify wire networks in a wiring diagram. When we start panel test or FAT/SAT (Factory Acceptance Test/Site Acceptance Test) it is very important to mention wire destination and source arrows so that… Continue Reading →
