Ground Fault Protection Testing Checklist [FREE PDF]

Ground fault protection is a critical electrical safety requirement mandated by NFPA 70 (National Electrical Code) and OSHA 29 CFR 1910.333 to prevent electrocution and electrical fires caused by unintended current paths to ground. Ground Fault Circuit Interrupters (GFCIs) and Ground Fault Protection of Equipment (GFPE) devices must be periodically tested to confirm proper operation, as a failed GFPE device provides no protection while appearing functional. This checklist provides a structured f

Pre-Test Documentation and Safety Review

Review existing records and establish safe working conditions before initiating ground fault protection testing.

  • Is the most recent ground fault protection test record available and does it show the last test date within the required interval?
  • Has the equipment manufacturer's testing procedure been obtained and reviewed prior to beginning the test?
  • Is appropriate PPE (arc-rated, voltage-rated gloves, face shield) available and selected for the voltage class of the equipment being tested?
  • Have all affected downstream personnel and departments been notified of potential power interruption during GFPE testing?
  • Is a calibrated ground fault test set or injection current test device available with a current certificate of calibration?

GFCI Receptacle and Device Inspection

Physically inspect and functionally test all GFCI receptacles and devices in required locations.

  • Are GFCI-protected receptacles installed in all required locations (bathrooms, kitchens, outdoor, garages, crawl spaces, unfinished basements, boathouses, and within 6 feet of sinks)?
  • Does each GFCI receptacle respond correctly when the TEST button is pressed (outlet de-energizes and RESET button pops out)?
  • Does the GFCI receptacle successfully reset after tripping and confirm power restoration with a plug-in outlet tester?
  • Have all downstream outlets protected by a GFCI device (GFCI-protected outlets) been verified to also lose power during a GFCI trip test?
  • Are GFCI receptacle faces, covers, and wallplates in good physical condition with no cracks, burn marks, or signs of moisture intrusion?
  • Provide a photo of GFCI devices tested showing TEST/RESET button and condition of faceplate?

GFPE Service Entrance and Feeder Testing

Test ground fault protection of equipment at service entrances and feeders rated 1000A or more.

  • Is ground fault protection of equipment (GFPE) installed on solidly grounded wye electrical services of more than 150V to ground but not exceeding 600V phase-to-phase, for services rated 1000A or more?
  • Is the GFPE pickup current setting within the allowable range (not to exceed 1200A)?
  • Is the GFPE maximum time delay setting within the allowable limit (not to exceed 1 second for ground fault currents equal to or greater than 3000A)?
  • Has the GFPE been performance-tested by injecting primary current to verify correct operation of sensors, relays, and trip mechanisms?
  • Is a written record of the performance test results, including the test date and the name of the person who performed the test, maintained on-site?

Equipment Grounding System Verification

Verify the integrity of the equipment grounding conductor system that enables ground fault protection to operate.

  • Is the equipment grounding conductor (EGC) continuous from the equipment to the service grounding point with no breaks, splices without proper fittings, or corrosion?
  • Is the grounding electrode conductor properly sized per NEC Table 250.66 for the size of the service entrance conductors?
  • Is the measured ground fault loop impedance at the service entrance within limits that will allow GFPE to operate at its set pickup current?
  • What is the measured ground resistance at the grounding electrode system (target: 25 ohms or less per NEC 250.56)?
  • Are grounding electrode conductor connections at the electrode (ground rod, plate, or structural steel) tight, corrosion-free, and protected from physical damage?

Current Transformer and Ground Fault Relay Testing

Test the sensing components of the GFPE system including zero-sequence CTs and relay modules.

  • Are zero-sequence current transformers (CTs) installed with all phase conductors and the neutral conductor (if grounded at service) passing through the CT window?
  • Is the secondary wiring from the current transformers to the ground fault relay intact, properly routed, and free from damage or moisture?
  • Has the ground fault relay been tested using the relay's own self-test function or an external test signal per the manufacturer's procedure?
  • Does the ground fault relay indicator or display confirm no active ground fault alarms prior to testing?
  • What is the actual measured trip time of the GFPE relay at the set pickup current during primary injection testing?

Temporary Power and Construction Site GFCI Compliance

Verify GFCI protection requirements for temporary power systems and construction or maintenance work areas.

  • Are all 125V, 15A, 20A, and 30A receptacles used for temporary power on construction sites protected by GFCI devices or an assured equipment grounding conductor program?
  • Are portable GFCI cord sets or GFCI-protected extension cords used when connecting portable tools and equipment in wet or damp locations?
  • Are portable GFCI devices tested with an outlet tester before each day of use or after any event that could cause damage?
  • Are generator-powered temporary electrical systems bonded and grounded in accordance with NEC Article 250 and the generator manufacturer's requirements?
  • Are all temporary power panels and distribution boxes protected from rain, moisture, and physical damage with weatherproof enclosures rated for the environment?

Test Findings, Failures, and Corrective Actions

Document all test failures, deficiencies, and required corrective actions with responsibility assignments.

  • Did all GFCI devices tested pass the TEST/RESET functional test without failures?
  • Did the GFPE system at the service entrance pass the primary current injection test and trip within the specified time delay?
  • List all GFCI or GFPE devices that failed testing including location, device type, failure mode, and required corrective action?
  • Have interim protective measures (temporary GFCI protection, area barriers, work restrictions) been implemented for any locations where protection is deficient?
  • Provide overall test summary notes, unusual findings, recommendations for equipment upgrades, or changes to the testing program?
