Job Description

Description:

The Electrical Field Service Technician installs, troubleshoots, tests, maintains, and documents electrical systems tied to generators, switchgear, transformers, control panels, auxiliary power units, and temporary or permanent site power equipment. This role is field-based and supports shop preparation, customer-site execution, commissioning support, rig up, rig down, and service work.

Power Generation Field Service

• Support diesel, natural gas, and packaged generator systems in the field.

• Assist with generator startup, commissioning, function checks, inspections, corrective work, and service readiness checks.

• Inspect batteries, chargers, alternator wiring, controllers, heaters, E-stops, alarms, shutdown circuits, and customer interface wiring.

• Support ATS, switchgear, transformer, panelboard, and temporary power system work based on training and authorization.

• Help set up and support load bank testing, including cable routing, connection checks, monitoring, and test documentation.

Site Rig Up and Rig Down

• Mobilize and demobilize generators, auxiliary power units, cable, grounding equipment, distribution gear, panels, skids, tooling, and consumables.

• Install temporary and semi-permanent electrical systems using conduit, flexible conduit, cord sets, cable tray, junction boxes, panelboards, disconnects, and control wiring.

• Lay out cable routes, protect cables from damage, maintain walking paths, and keep equipment access clear.

• Install grounding and bonding conductors, ground rods, jumpers, clamps, and terminations under IES procedures and site requirements.

• Verify equipment is staged, secured, labeled, documented, and ready for safe operation before turnover.

Electrical Installation, Testing, and Troubleshooting

• Pull, route, dress, label, terminate, and test low-voltage power wiring, control wiring, instrumentation wiring, and communication cabling.

• Perform continuity checks, insulation resistance checks, polarity checks, torque checks, phase rotation checks, and point-to-point verification.

• Read electrical drawings, wiring diagrams, schematics, one-lines, panel layouts, terminal schedules, and manufacturer manuals.

• Troubleshoot start circuits, E-stop circuits, relays, fuses, breakers, sensors, wiring harnesses, battery systems, chargers, alarms, shutdowns, and communication faults.

• Document findings with photos, measurements, test results, correction steps, redlines, and open punch items.

Safety, Quality, and Customer Communication

• Complete JSA, LOTO, pre-task planning, permits, and customer safety paperwork before work begins and when conditions change.

• Follow IES and customer safety rules for electrical work, PPE, driving, fall protection, rigging, hot work, stop work, and incident reporting.

• Maintain a clean work area, protect customer property, return unused materials, and control waste, scrap cable, fluids, and packaging.

• Communicate job status, delays, risks, and material needs to the supervisor before they become schedule problems.

• Represent IES professionally with customers, vendors, inspectors, OEM technicians, and other contractors.

Work Schedule and Travel Expectations

• Field schedule depends on customer workload, project schedule, and crew assignment. Work may include 10-hour, 12-hour, 14-hour, or 16-hour days where legal and approved.

• Technicians may support short-term rig up and rig down projects, long-term customer support rotations, shop preparation, commissioning, emergency response, and planned maintenance windows.

• Frequent travel, overnight stays, overtime, nights, weekends, holidays, and emergency callouts may be required.

• Reliable attendance matters. Field crews depend on each technician arriving fit for duty, prepared, and ready with required PPE, tools, and documentation.

Physical and Work Environment Requirements

• Lift and carry up to 50 lb. regularly and heavier items with mechanical help or team lift.

• Stand, walk, bend, kneel, climb, crawl, reach, grip tools, work from ladders or lifts, and access generator enclosures, skids, trailers, containers, and equipment rooms.

• Work outdoors in heat, cold, rain, wind, mud, dust, high noise, poor lighting, and congested industrial sites.

• Wear PPE for extended periods, including FR clothing, hard hat, safety glasses, hearing protection, gloves, fall protection, respirator when required, and arc-rated PPE when assigned.

• Work around energized or potentially energized equipment only when qualified, authorized, briefed, and protected by applicable electrical safety procedures.
