While red can be used as a live wire, it is often paired with black, which serves as the hot conductor. Red battery cables connect to the positive (+) terminal.
Red Battery Cable Positive Terminal Rule: Connecting Red to Positive Correctly
In USB cables, the red wire is the VCC, which is positive. The standard phase wire is brown, while blue serves as the neutral.
The neutral wire is typically blue, and the ground is green or green-yellow. In certain European three-phase systems, red might identify a specific phase rather than a simple positive/negative split.

Touching a red wire without verifying its state with a voltage tester is dangerous, as it may carry the full 120V or 230V potential depending on the region. While the standard international wiring code dictates that brown or black live wires connect to the positive side, the color red is often used as a secondary live conductor or for specific components like car audio systems.
