Which of the following is considered a basic principle of control circuit wiring?

Good labeling practices are essential in control circuit wiring because they ensure clarity and ease of troubleshooting. Proper labeling helps all individuals who interact with the system to quickly identify the function and connection of each wire. This practice reduces the likelihood of errors during installation and maintenance, facilitating efficient service and enhancing safety. Labeling also supports documentation efforts, allowing for better long-term management of electrical systems. Clarity in the wiring scheme helps maintain compliance with safety standards and industry regulations. In contrast, options that suggest using colored wires only, indicating that documentation is optional, or that all wiring must be completed before testing, do not prioritize the long-term reliability and safety that good labeling practices provide.
