ELECTRICAL INSPECTIONS CHECKLIST-SERVICE GROUNDING AND BONDING
1.1. Determine what grounding electrodes are present on the premises.
1.2. Determine which other electrodes are required or used.
1.3. Verify that the grounding electrode conductor or conductors and bonding jumpers are properly sized.
1.4. Verify that the grounding electrode conductors are protected and secured.
1.5. Verify that grounding electrode conductor enclosures are properly bonded.
1.6. Verify that the grounding electrode conductor is either unspliced or spliced using appropriate methods.
1.7. Check for correct size and installation of any rod, pipe, or plate electrodes.
1.8. Verify the accessibility of grounding electrode conductor connections.
1.9. Check for proper grounding electrode conductor connections, including buried connections.
1.10. Verify that metal water pipe installed in or attached to a structure is bonded.
1.11. Verify that exposed structural building frames are bonded.
1.12. Check for proper size and length of bonding jumpers around water meters and the like.
1.13. Check the size, type, and installation of the main bonding jumper.
1.14. Verify that service raceways and enclosures are correctly bonded.
1.15. Check the size of service-equipment supply-side bonding jumpers.
1.16. Verify that the grounded service conductor size is adequate.
1.17. Check separately derived systems for proper grounding electrodes, grounding electrode conductors, and system bonding jumpers.
1.18. Verify that water pipe and structural metal building frames in the area served by each separately derived system are bonded.
1.19. Verify that an intersystem bonding termination has been provided.
1.20. Verify that where a wire-type EGC is also used as a grounding electrode conductor, it meets all applicable requirements for both grounding electrode conductors and EGCs.
