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

Intermediate maintenance of generators and constant speed drive units transfers directly to the generator repair portion of this occupation.

How to prepare: Seek supervised motor and generator repair-shop practice in inspecting worn parts, measuring electrical performance, and reassembling units to specified ratings.

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 Installers and Repairers, Transportation Equipment

Maintenance of control units, voltage regulators, inverters, and converters provides relevant component-repair experience for transportation electrical systems.

How to prepare: Complete hands-on training in wiring and relay diagnosis for the transportation equipment you intend to service.

What the civilian work involves
  • Inspect and test electrical systems and equipment to locate and diagnose malfunctions, using visual inspections, testing devices, and computer software.
  • Reassemble and test equipment after repairs.
  • Adjust, repair, or replace defective wiring and relays in ignition, lighting, air-conditioning, and safety control systems, using electrician's tools.
