Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Electric Motor, Power Tool, and Related Repairers

Inspecting, servicing, and repairing mobile facility generators transfers directly to the generator-repair portion of this occupation.

How to prepare: Take a hands-on motor and generator repair course focused on electrical measurements, component rebuilding, and reassembly.

What the civilian work involves
  • Inspect and test equipment to locate damage or worn parts and diagnose malfunctions, or read work orders or schematic drawings to determine required repairs.
  • Measure velocity, horsepower, revolutions per minute (rpm), amperage, circuitry, and voltage of units or parts to diagnose problems, using ammeters, voltmeters, wattmeters, and other testing devices.
  • Repair and rebuild defective mechanical parts in electric motors, generators, and related equipment, using hand tools and power tools.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Maintaining and repairing mobile facility electrical equipment provides a foundation for commercial and industrial equipment repair.

How to prepare: Complete a practical industrial electronics troubleshooting course that includes fault diagnosis and post-repair equipment testing.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Set up and test industrial equipment to ensure that it functions properly.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
