Protective Grounds Testing Services
Comprehensive testing and inspection of personal protective grounding equipment to ensure worker safety during electrical de-energization and grounding operations.
Life-Saving Equipment for De-Energized Work
Protective grounding equipment is the last line of defense against accidental energization, ensuring workers are protected when performing maintenance on supposedly de-energized electrical systems.
Our testing services comply with ASTM F2249 standards, providing comprehensive electrical resistance testing, visual inspection, and mechanical verification to ensure your grounding equipment will perform when lives depend on it.
Protective Grounding Equipment We Test
Comprehensive testing for all types of personal protective grounds
Ground Sets & Assemblies
Complete protective grounding assemblies including cables, clamps, ferrules, and connectors used for equipotential bonding during de-energized work.
MACs (Manual Application Clamps)
Protective grounds with integrated rubber glove jumper handles for safe manual application on energized or potentially energized conductors.
Our Testing Process
Rigorous multi-stage testing ensures equipment reliability when it matters most
Receiving & Documentation
Each grounding assembly is logged with unique identification, photographed, and assigned a tracking number for complete traceability.
Visual Inspection
Thorough examination for cable damage, frayed strands, corroded connections, broken clamps, or any signs of deterioration per ASTM F2249.
Mechanical Testing
Verification of clamp operation, jaw alignment, spring tension, and ferrule integrity to ensure proper mechanical function.
Resistance Testing
Precision measurement of end-to-end electrical resistance using four-wire Kelvin measurement to verify low-resistance path integrity.
Pass/Fail Analysis
Results evaluated against ASTM F2249 standards and manufacturer specifications. Failing equipment is marked and documented.
Certification & Return
Passing equipment is labeled with test date and certification. Complete test records and certificates are provided.
Every Test Includes
Testing Requirements & Standards
OSHA Requirements
OSHA 1910.269 requires that protective grounding equipment be tested before first use and periodically thereafter.
- Before first use
- Before each use (visual inspection)
- When there is reason to suspect damage
- Following any repairs
ASTM F2249 Standard
Standard Specification for in-service testing of temporary protective grounding equipment used on de-energized systems.
- Resistance testing requirements
- Visual and mechanical inspection criteria
- Maximum acceptable resistance values
- Pass/fail criteria defined
Testing Intervals
Recommended Schedule to maintain compliance and worker safety.
- Heavy Use: Every 6 months
- Moderate Use: Annually
- Light Use: Every 2 years
- After Fault: Immediately
Resistance Testing Specifications
Per ASTM F2249, protective grounding assemblies must maintain low resistance to ensure effective fault current path:
