Correctly identifying live, neutral, and ground wires is the foundation of safe electrical work. With Royal Cord wire widely used in the Philippines-from household wiring to industrial projects-color recognition ensures both compliance with safety codes and user protection. This article explains wire color coding, Royal Cord's typical configurations, common mistakes, and why our company is the reliable supplier for the Philippine market.
What Is Royal Cord Wire and Why Is Color Identification Important?
Royal Cord wire is a flexible cable type, available in royal cord 2c, royal cord 3 wire, and royal cord 3c models. Its multi-core structure allows simultaneous transmission of live, neutral, and ground conductors. Because incorrect connections can cause shocks or fire hazards, color recognition is critical.
The Three Conductors in Electrical Systems
Every AC wiring system includes:
- Live (Hot): supplies power.
- Neutral: completes the circuit.
- Ground: safely diverts fault currents to earth.
International Color Coding Standards
| Function | IEC Standard Color | Philippine Common Practice |
|---|---|---|
| Live (Hot) | Brown or Red | Black or Red |
| Neutral | Blue or Black | White or Blue |
| Ground (Earth) | Green/Yellow stripes | Green or Green/Yellow |
Common Color Configurations in Royal Cord
| Royal Cord Type | Typical Colors | Usage Notes |
|---|---|---|
| 2-Core (2C) | Black (Live), White (Neutral) | Standard household loads |
| 3-Core (3C) | Black (Live), White (Neutral), Red (Optional ground/second live) | Flexible circuits |
| 4-Core | Black, White, Red, Green (Ground) | Safer grounding support |
How to Correctly Identify Live, Neutral, and Ground
- Live: Usually black or red.
- Neutral: Typically white or blue.
- Ground: Green or green/yellow in 3C or 4C models.
When uncertain, always confirm with:
- Cable markings
- A multimeter test
- Philippine Electrical Code guidelines
Common Mistakes and Risks
| Mistake | Possible Risk |
|---|---|
| Swapping live and neutral | Appliance damage, malfunction |
| Misidentifying ground | Electric shock, fire hazard |
| Ignoring supplier differences | Non-compliance with PEC |
