Chapter 6: Inspection and Testing

BS 7671 requires electrical installations to undergo thorough inspection and testing to ensure safety, reliability, and compliance with regulations.

Overview of Chapter 6 – Key Inspection and Testing Procedures

6.1 Initial Verification

• Ensures that new installations comply with BS 7671 before being energized.
• Includes **visual inspection** to check wiring, connections, and protective devices.
• Requires **testing of continuity, insulation resistance, polarity, and earth fault loop impedance**.

6.2 Periodic Inspection and Testing

• Ensures ongoing safety and compliance of existing installations.
• Identifies **wear and tear, deterioration, and potential hazards**.
• Requires **electrical installation condition reports (EICRs)**.

6.3 Testing Methods

• Includes **dead testing** (continuity, insulation resistance, polarity checks).
• Includes **live testing** (earth fault loop impedance, RCD testing, prospective fault current).
• Ensures **correct operation of protective devices**.

6.4 Certification and Documentation

• Requires **Electrical Installation Certificates (EICs)** for new installations.
• Requires **Minor Works Certificates** for modifications.
• Ensures proper **record-keeping for compliance and future reference**.

Why Chapter 6 Matters

• Ensures **electrical installations remain safe and compliant**.
• Prevents **hazards caused by faulty wiring or deteriorated components**.
• Provides **guidelines for proper testing and certification**.
