5. Quick Reference Cheat Sheet (Based on IEC 60949)

| Clause | Key Requirement | Typical Application | |-----------|----------------------|--------------------------| | 1 – Scope | Defines equipment categories (e.g., MCC, switchboards). | Clarifies whether a device falls under IEC 60949 or IEC 61439. | | 3 – Construction | Minimum clearance, creepage distances, and enclosure ratings. | Design of panels for dusty or humid environments. | | 4 – Temperature Rise | Limits on permissible temperature increase under load. | Selection of components to avoid overheating. | | 5 – Mechanical Strength | Tests for impact, vibration, and short‑circuit forces. | Validation of robust mounting hardware. | | 7 – Testing | Detailed procedures for type testing, routine testing, and verification. | Certification labs use these methods for compliance certificates. | | 8 – Marking | Mandatory markings: voltage class, frequency, IP rating, etc. | Ensures field personnel can quickly identify safe operating limits. |
