Grounding and bonding system maintenance checklists for the quarterly and annual rounds: 2 free lists, 9 items and 13 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against NEC (NFPA 70) and NETA acceptance and maintenance testing; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Grounding and bonding system quarterly maintenance checklistquarterly
- Every quarter, walked with the service and panel round since a compromised ground shows up as noise and nuisance trips there first. Run by: The electrician or maintenance tech on the quarterly electrical round.
- Grounding and bonding system annual maintenance checklistannual
- Once a year, scheduled with the testing firm's visit so the resistance-to-ground measurement can be witnessed and logged rather than taken on faith. Run by: The testing firm performs the ground-resistance measurement; the electrician observes, records the readings and inspects the accessible connections.
What most often fails on a grounding and bonding system
- A bonding jumper on a water main or gas line found removed after a plumbing repair and never reinstalled, so a bonded metal path is now floating.
- Corrosion building at an exterior ground clamp until the connection is more rust than metal, while the conductor above it still looks fine.
- A ground bar with lugs backed off or double-lugged past what the terminal allows, so several equipment grounds share a connection that isn't solid.
- A resistance reading written down with no reference to the prior year, so a ground that is slowly drying out and climbing goes unnoticed until it's out of range.
- The test performed only at the main electrode while a separately driven ground for a remote panel or antenna is never measured.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which grounding and bonding system maintenance rounds do these checklists cover?
- Grounding and bonding system quarterly maintenance checklist (quarterly): Every quarter, walked with the service and panel round since a compromised ground shows up as noise and nuisance trips there first. Grounding and bonding system annual maintenance checklist (annual): Once a year, scheduled with the testing firm's visit so the resistance-to-ground measurement can be witnessed and logged rather than taken on faith.
- Who runs the grounding and bonding system maintenance round?
- The electrician or maintenance tech on the quarterly electrical round. The testing firm performs the ground-resistance measurement; the electrician observes, records the readings and inspects the accessible connections.

- Which standards is grounding and bonding system work verified against?
- NEC (NFPA 70), published by the National Fire Protection Association; NETA acceptance and maintenance testing, published by the InterNational Electrical Testing Association. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (9 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
