Civilian Career Paths

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.

Electricians

Military installation and maintenance of interior electrical systems and equipment directly overlap with civilian electrical installation and maintenance work.

How to prepare: Submit documented military electrical experience to an apprenticeship sponsor for assessment of credit and remaining training gaps: most electricians complete a 4- or 5-year apprenticeship, but military experience and testing may qualify you for a shortened program. A high school diploma or equivalent is required, and most states require licensing and an examination covering the National Electrical Code and state and local codes.

What the civilian work involves
  • Prepare sketches or follow blueprints to determine the location of wiring or equipment and to ensure conformance to building and safety codes.
  • Place conduit, pipes, or tubing, inside designated partitions, walls, or other concealed areas, and pull insulated wires or cables through the conduit to complete circuits between boxes.
  • Assemble, install, test, or maintain electrical or electronic wiring, equipment, appliances, apparatus, or fixtures, using hand tools or power tools.
