Separable Connector AC Withstand Test (IEEE 386)

Inspection template for recording the one-minute AC withstand test on loadbreak and deadbreak separable connectors and bushings in accordance with IEEE 386 as part of routine accessory testing.

Test Record and Unit Identification

• Test date and time recorded
• Unit identification, catalog number, and serial number recorded
• Connector type identified
• Rated voltage class recorded

Safety Preconditions and Work Readiness

• Test area controlled and barricaded
  High-voltage test area is restricted to authorized personnel and clearly barricaded.
• Appropriate PPE worn for energized test setup
  Verify arc-rated PPE, voltage-rated gloves where required, eye/face protection, and other task-specific PPE per site procedure and OSHA 1910 Subpart I / NFPA 70E.
• Test equipment verified in calibration status
  AC test set, voltmeter, timer, and any monitoring devices are within current calibration or verification interval.
• Work instructions and IEEE 386 test procedure available

Visual Condition and Test Setup

• Connector and bushing surfaces clean, dry, and free of visible damage
  Inspect for cracks, tracking, contamination, swelling, punctures, carbonization, or other non-conformance before energizing.
• Test leads and terminations properly connected
  Verify secure connections, adequate spacing, and no exposed unintended conductors.
• Grounding and discharge provisions in place
  Confirm proper grounding, discharge tools, and safe de-energization steps are available before and after the test.
• Ambient conditions suitable for test
  Record relevant conditions such as temperature, humidity, contamination, or other factors affecting the test.

AC Withstand Test Parameters

• Applied test voltage recorded
  Record the actual AC withstand voltage applied during the test.
• Test duration recorded
  IEEE 386 routine record for a one-minute AC withstand test.
• Test frequency recorded
  Record the test frequency used by the AC withstand source.
• Test configuration selected

Results, Deficiencies, and Sign-Off

• No flashover, puncture, or breakdown observed during test
  Any flashover, puncture, insulation breakdown, or abnormal discharge is a critical non-conformance.
• Leakage current or abnormal behavior recorded
  Record leakage current, corona, audible discharge, or other observed abnormalities if applicable.
• Test result disposition
• Inspector signature
