1.1. Identify the wiring methods in use and verify their suitability for the occupancy and conditions.
1.2. Verify that all conductors of a circuit are grouped together.
1.3. Check insulation values where conductors of different systems share common enclosures.
1.4. Check wiring methods for spacing from edges of framing and for protection from nails and screws.
1.5. Check for insulating bushings or grommets where NM cable is installed through metal studs or where insulated conductors 4 AWG or larger enter enclosures.
1.6. Check cover, fill, protection, and allowances for ground movement on underground conductors and raceways.
1.7. Verify that electrical raceways and cable trays are used exclusively for electrical conductors.
1.8. Check for continuity and completeness in metal raceways and enclosures.
1.9. Verify that wiring methods are securely fastened in place, supported independently of suspended ceilings, and not used as supports.
1.10. Check for continuity of grounded conductors in multiwire branch circuits.
1.11. Check for adequate length of free conductors in boxes.
1.12. Verify that boxes are installed at junction, splice, outlet, switch, and pull points.
1.13. Check conductor fill in raceways.
1.14. Verify that raceway systems are complete prior to installation of conductors.
1.15. Check vertical raceways for adequate conductor supports.
1.16. Verify that fire ratings have been restored at electrical penetrations.
1.17. Check installations of wiring in ducts, plenums, and other air- handling spaces for proper methods and materials.
