Distribution Line Protective Grounding and Equipotential Verification

Inspection template for verifying temporary protective grounds, equipotential bonding, and work-zone controls before crews begin work on de-energized overhead or underground distribution lines under OSHA 1910.269 and related grounding/equipotential requirements.

Job Setup and De-Energized Work Authorization

• Work location, circuit, and structure identified on the job brief
• Clearance or switching order confirms the line is de-energized for the work scope
• All sources of backfeed, induced voltage, and stored energy identified
• Crew briefing completed on grounding plan and equipotential zone boundaries

Temporary Protective Grounds

• Grounding set installed at the approved location(s) per work plan
• Grounding conductors are connected to the line and to an effective grounding point
• Grounding clamps are fully seated, tight, and free of visible damage or contamination
• Grounding conductors are sized and arranged to minimize impedance and step/touch exposure
• Grounds are visible to the crew and not hidden by covers, vegetation, or equipment

Equipotential Zone and Bonding

• Equipotential zone established before work begins
• All workers in the zone are bonded or otherwise protected from potential differences
• Aerial device, truck, or other conductive equipment is bonded as required by the work plan
• Bonding jumpers are routed to prevent trip hazards, abrasion, and accidental disconnection
• No unbonded conductive objects are present within the work zone

Testing and Verification

• Absence of voltage verified at the work location using an approved test method
• Test instrument was verified before and after use
• Grounding and bonding continuity verified after installation

Deficiencies and Release to Work

• Any deficiency identified was corrected before work started
• Inspector documented final release to proceed with de-energized work
• Inspector signature
