Switchgear Installation Guidelines

1. Mount on dedicated backplane in switchgear compartment

2. Maintain 75mm clearance from protective relays

3. Use 50mm² minimum copper conductors with compression lugs

4. Implement single-point cabinet grounding (<0.05Ω resistance)

5. Verify circuit isolation before energization

6. Align with cabinet ventilation paths for optimal cooling

Performance Validation Tests

Compliance & Standards

• IEC 61000-6-5 (Power station emissions)

• IEC 62271-200 (AC metal-enclosed switchgear)

• ANSI/IEEE C37.20.2 (Medium-voltage switchgear)

• EN 50522 (Earthing of power installations)

Maintenance Protocol

Safety Considerations

• De-energize switchgear compartment before installation/service

• Verify discharge of capacitive elements (5τ time constant)

• Use CAT IV-rated PPE per NFPA 70E

• Follow LOTO procedures during maintenance

• Install warning labels for capacitive energy storage
