What color code is typically used for a live wire?

In electrical wiring, the color code for a live wire typically uses red. This is a standardized practice in many regions to ensure safety and consistency when working with electrical circuits. The live wire is the conductor that carries electrical current to the load, and using red helps to clearly identify it among other wires, which can prevent accidental contact and hazards.

Red is often paired with other colors that designate neutral and ground wires, making it easier for technicians and anyone involved in electrical work to discern the purpose of each wire. This color coding is crucial for maintaining safety protocols during installation, maintenance, or repairs in electrical systems.

The other colors mentioned, such as black, yellow, and white, have different meanings in various contexts. For instance, in some systems, black is often used for a second live or phase wire, yellow might indicate a switched live or a non-standard configuration, and white is typically used for neutral wires. Understanding these distinctions is essential for proper identification and handling during electrical work.
