Blue wire in the secondary distribution box

When present, the blue wire typically functions as a secondary ungrounded (hot) conductor. It is often used as a “traveler” wire in three-way or four-way switch configurations, passing the electrical signal between multiple switches that control a single light fixture. This color-coding is crucial for ensuring safe installations and maintenance, especially considering that improper wiring can lead to severe hazards. Blue doesn't mean one thing everywhere. Wiring rules change by country, voltage, and application. In many places that follow IEC rules, blue tells you. Electrical wire color coding is a standardized system that provides essential information about a conductor's function within a circuit, promoting safety and system integrity. They're often used in interconnected systems like three-way switches. White (or Gray) Wires: Act as neutral wires, completing the circuit to the power. These color codes are used for electrical distribution systems, and while some are mandatory, others are optional. The American Society for Testing and Materials (ASTM) and the National Electric Code (NEC) have established specific guidelines for wire color coding.
