What are the basic principles of electrical secondary circuit marking? - Solutions - Huaqiang Electronic Network
For ease of installation, operation, and maintenance, all wiring in the electrical secondary circuit is clearly labeled with a secondary circuit number. These labels typically consist of numbers or a combination of numbers and words that indicate the function and purpose of each loop. This labeling system ensures that every component can be easily identified and traced during troubleshooting or maintenance. The fundamental principle of circuit labeling involves connecting all equipment through terminal blocks using control cables. Additionally, devices mounted on the top of the panel and those inside the panel also need to connect via terminal rows. In such cases, the top-mounted devices are treated as off-panel components, and their connections follow the same loop numbering principle, ensuring consistent and clear labeling. To enhance clarity, different reference methods are used for DC and AC loops. Each loop within both systems is assigned a unique identifier, making it straightforward to determine the nature of the loop from its label. This systematic approach greatly simplifies the process of maintenance, repairs, and future modifications, saving time and reducing errors in complex electrical systems.
