Electrical Quality Control Checklist

Use this Electrical Quality Control Checklist as a template to conduct QA of wiring, connections, installations, and electrical safety measures.

1. Are all electrical works being performed according to site-specific safety regulations?

2. Is proper PPE (gloves, insulated tools, boots) available and worn by electricians?

3. Is the work area free from water, debris, and other hazards?

4. Are safety signs and lockout/tagout procedures in place during work?

5. Are live wires de-energized and properly isolated before inspection?

1. Are all electrical components (wires, breakers, panels) verified against project specifications?

2. Are materials stored in dry, protected areas to prevent corrosion or damage?

3. Are manufacturer certifications and batch numbers recorded for traceability?

4. Are cables and conduits stored properly to avoid bending, crushing, or exposure?

1. Are conduit runs properly aligned, supported, and secured at specified intervals?

2. Are cable trays and ducts clean, unobstructed, and compliant with the design layout?

3. Are wire types (e.g., copper, aluminum) and insulation ratings suitable for the application?

4. Are color codes and labeling consistent and compliant with local electrical codes?

5. Are grounding and bonding connections securely made with approved materials?

1. Are panelboards mounted level and accessible with clear space around them?

2. Are circuit breakers correctly sized and labeled per circuit designation?

3. Is internal wiring neat, secure, and terminated using proper torque values?

4. Are bus bars clean, aligned, and free from signs of overheating?

5. Are protective covers installed after verification?

1. Are electrical devices (outlets, switches, lights) securely mounted and connected?

2. Are terminations checked for tightness, polarity, and insulation stripping accuracy?

3. Are enclosures sealed and weatherproofed (if applicable)?

4. Are junction boxes accessible, labeled, and not overfilled beyond capacity?

5. Are flexible cables and connectors used only where necessary and properly secured?

1. Are continuity and insulation resistance tests conducted and recorded?

2. Are polarity and phase rotation checks completed?

3. Are earth resistance and loop impedance tests within acceptable limits?

4. Is functional testing performed on lighting, control systems, and powered equipment?

5. Are test results reviewed and approved before energizing circuits?

1. Are installation drawings updated to reflect actual wiring (as-built)?

2. Are inspection checklists, permits, and approvals filed and signed off?

3. Are quality control records maintained for each system or area tested?

4. Is a handover pack prepared with warranties, manuals, and test certificates?

5. Are corrective actions tracked and closed out in case of defects?
