Switchgear and Breaker Functional Test Record

Inspection template for documenting switchgear and power circuit breaker functional testing, including insulation resistance, contact resistance, trip timing, and primary injection results against ANSI/NETA acceptance criteria.

Test Record and Job Information

• Equipment identification recorded
  Record switchgear lineup, breaker identifier, voltage class, manufacturer, model, serial number, and location.
• Test date and test location recorded
  Document the date, facility, room, and specific equipment location where testing was performed.
• Qualified personnel performing test
  Identify the qualified person or testing company responsible for the inspection and test record.
• Reference standard and acceptance criteria documented
  Confirm the record references applicable ANSI/NETA acceptance values and the project or owner-specific test procedure.

Safety Preconditions and Test Readiness

• Lockout-tagout applied and verified
  Verify the equipment is de-energized, isolated, and controlled under lockout-tagout before testing.
• Absence of voltage verified
  Confirm absence of voltage on the circuit and test points before contact with conductors or terminals.
• PPE appropriate for arc flash and shock hazard
  Verify required PPE was selected based on the hazard assessment and was worn during the test.
• Test instruments calibrated and within date
  Confirm insulation resistance tester, micro-ohmmeter, timing equipment, and primary injection set are calibrated and in service.
• Work area secured and barricaded
  Verify the test area is controlled, access is restricted, and warning signs or barricades are in place.

Visual and Mechanical Inspection

• Breaker and switchgear enclosure free of damage or contamination
  Inspect for signs of overheating, corrosion, moisture intrusion, loose hardware, contamination, or physical damage.
• Insulators, bushings, and barriers in acceptable condition
  Check for cracks, tracking, carbonization, missing barriers, or other visible defects.
• Mechanical operation and racking mechanism functional
  Verify the breaker can be racked, opened, closed, and mechanically operated without binding or abnormal resistance.
• Control wiring, terminals, and auxiliary devices inspected
  Check control wiring, terminal tightness, auxiliary contacts, indicators, and interlocks for visible defects.
• Nameplate and breaker settings verified
  Confirm nameplate data, trip unit settings, and coordination-related settings match the approved design or test plan.

Insulation Resistance Testing

• Test voltage applied per procedure
  Record the insulation resistance test voltage used for the breaker or switchgear assembly.
• Phase-to-phase insulation resistance
  Record measured insulation resistance between phases and compare to ANSI/NETA acceptance criteria and project requirements.
• Phase-to-ground insulation resistance
  Record measured insulation resistance from each phase to ground and note any abnormal leakage or low readings.
• Insulation resistance results acceptable
  Confirm the measured values meet the minimum acceptance criteria for the equipment class and test procedure.

Contact Resistance and Continuity

• Micro-ohm test performed on main contacts
  Measure and record contact resistance of each pole or phase using a calibrated low-resistance ohmmeter.
• Phase resistance values balanced within acceptable tolerance
  Verify the resistance readings are reasonably balanced across poles and do not indicate a loose or damaged contact path.
• Continuity of control and trip circuits verified
  Confirm continuity of trip coils, close coils, shunt trip, and control circuit conductors as applicable.
• Contact resistance results acceptable
  Confirm the measured contact resistance values meet the project or ANSI/NETA acceptance criteria.

Trip Time and Primary Injection Testing

• Primary injection test performed
  Apply primary current to verify breaker trip operation and current path integrity.
• Trip time recorded
  Record the measured trip time for each pole or phase during primary injection or functional trip testing.
• Trip operation within acceptable limits
  Confirm the breaker trips within the acceptable time and functional limits specified by the manufacturer and ANSI/NETA criteria.
