For what purpose are cables and wires marked in electrical systems?

In electrical systems, cables and wires are marked primarily to assist technicians in troubleshooting. Markings provide crucial information about the specific function, properties, and conditions of the wiring, which allows technicians to quickly identify and address issues. For instance, if a wire is marked with its intended use, voltage, or other specifications, a technician can diagnose faults more efficiently and ensure they take the correct safety precautions while working on the system.

While markings may enhance safety and provide essential identification, the ultimate goal is to support the troubleshooting process, making it easier for technicians to navigate complex electrical systems. This importance of facilitating maintenance and repairs underscores the necessity of clear and consistent labeling within electrical installations.
