Flow-Diagram Exercise for Electrical Codes and QA/QC Compliance

Purpose

The purpose of this KPT is to:

• Develop learners’ understanding of the step-by-step QA/QC process in electrical projects.
• Provide a visual, vocational learning tool that illustrates workflow for inspections, testing, reporting, and escalation.
• Show how UK legislation and standards guide each step of electrical QA/QC activities.
• Enhance learners’ analytical, decision-making, and competency skills in realworld QA/QC scenarios.
• Produce portfolio-ready evidence demonstrating the learner’s ability to link process with legal and technical compliance.

Key Vocational Competencies Covered:

• Mapping workflow to UK electrical standards (BS 7671, IEC, EAWR 1989).
• Differentiating QA (preventive) from QC (verification) activities.
• Performing inspections, risk assessments, and escalations safely.
• Completing audit-ready documentation following ISO 9001:2015 standards.

Vocational Scenario

Scenario:

You are a QA/QC Electrical Officer on a commercial refurbishment project in London. Your duties include:

• Inspecting newly installed circuits, switchgear, and distribution boards.
• Completing QA/QC reports to confirm compliance with UK electrical regulations.
• Escalating non-conformities to supervisors or clients.
• Verifying corrective actions are implemented.

Learning Objective: Use a flow-diagram to sequence inspection, reporting, escalation, and closure processes while linking them to UK standards.

Detailed Step-by-Step Guidance

Step 1: Plan QA/QC Inspection

• Objective: Define inspection scope, location, personnel, and schedule.
• Link to Standards: BS 7671:2018; ISO 9001:2015.
• Vocational Action: Prepare checklist for circuits, switchgear, and PPE verification.
• Example: “Inspection of Level 2 lighting circuits; assign John Smith as inspector; schedule inspection for 09:00, 15 January 2026.”

Step 2: Review Relevant UK Legislation & Standards

• Objective: Ensure inspection complies with legal and technical standards.
• Relevant Legislation:
  • BS 7671:2018 – Wiring Regulations.
  • Electricity at Work Regulations 1989 (EAWR) – safe electrical work.
  • Health and Safety at Work Act 1974 (HSWA) – worker safety.
  • ISO 9001:2015 – documentation and audit compliance.
• Vocational Action: Inspectors review standards before visiting site; ensure tools and checklists are compliant.

Step 3: Conduct Risk Assessment

• Objective: Identify hazards and preventive measures.
• Potential Hazards: Electric shock, cable trip hazards, fire risk.
• Vocational Action: Complete risk assessment template; assign likelihood, everity, and controls.
• Example: “Electric shock – Medium likelihood, High severity; controls: PPE, isolation, insulation checks.”

Step 4: Perform Visual Inspection

• Objective: Check installation quality and compliance.
• Vocational Action: Inspect cable routing, colour coding, earthing, and labelling.
• Example: “Cables properly clipped; breakers in distribution board labelled correctly; earthing visible.”

Step 5: Perform Functional / Electrical Testing

• Objective: Verify system performance and safety.
• Tests Performed: Insulation resistance, continuity, polarity, earth fault loop impedance.
• Vocational Action: Record readings, compare against BS 7671 thresholds.
• Example: Insulation resistance: 2.5 MΩ (Pass); Continuity test: Pass.

Step 6: Document Findings in QA/QC Report

• Objective: Record inspection observations and test results.
• Vocational Action: Complete report template with: inspector name, date, standard references, findings, and non-conformities.
• Example: “Lighting circuit Level 2 inspected; breakers correctly installed; insulation tests recorded; minor labelling issue noted.”

Step 7: Identify Non-Conformities

• Objective: Highlight deviations from standards.
• Vocational Action: Record issues such as missing PPE, mislabelled breakers, or failed tests.
• Example: “Breaker labels missing on circuits L3 and L4; insulation test records incomplete.”

Step 8: Escalate Critical Issues

• Objective: Ensure immediate action for safety or compliance risks.
• Vocational Action: Notify supervisor or project manager; provide supporting evidence.
• Example: “Breaker mislabelling escalated to site manager; work halted until corrected.”

Step 9: Implement Corrective Actions

• Objective: Address non-conformities identified during inspection.
• Vocational Action: Correct labelling, re-test circuits, verify PPE compliance.
• Example: “Labels applied; insulation readings re-taken; all electricians reminded to wear PPE.”

Step 10: Verify Corrective Actions Completed

• Objective: Confirm that corrective actions meet standards and are effective.
• Vocational Action: Follow-up inspection and re-test.
• Example: “Level 2 circuits re-tested; insulation readings compliant; breaker labels verified.”

Step 11: Close Inspection & Record for Audit

• Objective: Complete audit-ready documentation.
• Vocational Action: File all templates, reports, and photos in project QA/QC records.
• Example: “Inspection report signed, dated, and archived; evidence uploaded to ISO 9001 audit folder”.

Guided Reflective & Analytical Questions

• Why is planning the inspection the first step in the QA/QC workflow?
• How does linking each step to UK legislation prevent incidents and noncompliance?
• What is the difference between QA preventive actions and QC verification steps in the flow-diagram?
• How should critical vs minor non-conformities be escalated and documented?
• Why is documenting all findings and corrective actions essential for ISO 9001:2015 audits?
• How could skipping the verification step compromise safety or legal compliance?
• Suggest improvements to increase efficiency while maintaining safety and compliance in the QA/QC process.

Learner Task

1. Create a visual flow-diagram for QA/QC inspection of a real or hypothetical electrical project.
2. Include all 11 steps from planning to audit closure.
3. Indicate decision points for minor vs critical non-conformities.
4. Annotate each step with the relevant UK standard or regulation.
5. Identify QA preventive measures and QC verification checks at each stage.
6. Reflect on how following this workflow prevents incidents, ensures compliance, and supports audit readiness.
7. Submit the completed diagram with a brief explanation for each step.
