• Troubleshoot AC and DC motors, motor-control systems, MCCs, contactors, relays, circuit breakers, transformers, switchgear, and industrial power-distribution equipment.
• Use schematics, one-line diagrams, ladder diagrams, wiring diagrams, PLC programs, OEM documentation, and field measurements to identify and resolve equipment failures.
• Perform root-cause analysis of recurring or catastrophic equipment failures and recommend corrective actions.
• Identify obsolete, unreliable, or problematic equipment and recommend repair, retrofit, or upgrade solutions.
• Perform approved field modifications to electrical wiring, control circuits, PLC programs, VFD configurations, and control-system settings.
• Verify proper system operation following repair, modification, or commissioning.
• Provide technical direction and mentorship to field technicians, electricians, and junior engineers.
• Coordinate troubleshooting, repair, and commissioning activities with customers, operations personnel, engineering teams, vendors, and OEM technical support.
• Maintain detailed service documentation, including failure symptoms, diagnostic findings, root cause, repairs performed, components replaced, parameter changes, and recommendations.
• Provide customers and management with clear technical explanations and service recommendations.
