5. Acceptance Criteria

• Compliance with Standards: All work must comply with national codes and standards (NEC, IEC, local regulations).
• Functionality: All electrical systems must be fully functional, including power, lighting, and emergency systems.
• Safety Standards: Electrical installations must meet safety standards to avoid risks of electric shock or fire hazards.
• Documentation: All tests must be documented, and certificates must be provided to confirm compliance.

---

6. Documentation and Reporting

• Inspection Reports: Detailed reports from inspections and tests.
• Test Certificates: For each major component and system (e.g., insulation resistance certificates, earthing test certificates).
• Sign-offs: All inspections and tests must be signed off by the responsible parties, such as the electrical engineer, commissioning engineer, and quality control inspector.
• As-Built Drawings: Updated drawings reflecting actual installations and modifications.

---

7. Health, Safety, and Environmental Considerations

• Lockout/Tagout: Ensure lockout/tagout procedures are followed during all electrical testing.
• Personal Protective Equipment (PPE): Workers must wear appropriate PPE such as insulated gloves, helmets, and safety boots during electrical work.
• Environmental Impact: Disposal of any hazardous electrical waste (e.g., damaged insulation or batteries) must be handled in accordance with environmental regulations.
