Job description

Position Summary

The Quality Technician – Assembly is responsible for executing final electrical and mechanical testing and inspection on completed switchgear, power distribution, and related assemblies prior to shipment. This role is the last line of quality verification at Assembly, ensuring all units pass functional, electrical safety, and workmanship requirements before release. The Quality Technician operates and documents results for hi-pot, insulation resistance, breaker trip, and control wiring tests and executes final visual and mechanical inspections. Supports the QC Inspector with in-process inspection activities and nonconformance documentation as workload allows.

Key Responsibilities

Final Electrical Testing & Verification

• Execute final electrical testing per applicable test procedures and checklists, including:
• Hi-pot (dielectric withstand) testing at specified test voltages; verify no flashover or excessive leakage current
• Insulation resistance testing
• Breaker trip and ground fault testing
• Current transformer turns ratio testing per specified acceptance criteria
• Control wiring point-to-point continuity verification per schematic
• Functional testing of control power, breaker components, and associated control circuits per applicable procedures
• Troubleshoot and diagnose test failures, including identifying root causes of electrical faults, wiring errors, or component issues, and elevate findings to the QC Manager.
• Operate, maintain, and verify calibration status of test equipment; record calibration dates on each test report
• Record all test results, measured values, and pass/fail determinations accurately on the test report; upload completed documentation per document control procedures

Final Visual & Mechanical Inspection

• Perform visual and mechanical inspection checks per applicable QC procedures, including hardware installation and torque, phase labeling, control wiring anchorage, component and lug verification against BOM, and breaker function checks
• Document inspection results and note any discrepancies for disposition
