## Cable Conductor Classes 1, 2, 5 & 6

Understanding these classes helps in selecting the right cable for the right application.

**Class 1 – Solid Conductor:** Rigid construction, commonly used in fixed wiring.

**Class 2 – Stranded Conductor:** Multiple strands, widely used in power cables and fixed industrial installations.

**Class 5 – Flexible Conductor:** Fine copper strands, commonly used in control cables, panel wiring, and flexible power cables.

**Class 6 – Extra-Flexible Conductor:** Finer strands than Class 5, used where greater flexibility is required.

The right conductor class improves installation convenience and helps meet application requirements.

These conductor classes are defined under **[IEC 60228.](https://forumelectrical.com/top-12-iec-standards-in-electrical-engineering/)** Always verify the applicable product standard and flexing requirements before selecting a cable.
