Current service use not established

This code is listed in the directory. Inclusion alone does not confirm current service use.

A Navy Enlisted Classification: a skill designation sailors hold in addition to their rating. Part of the Construction Electrician rating

Overview

An advanced construction electrician applies foremanship and advanced electrical theory to plan installations and troubleshoot electrical systems to the component level. The electrician installs and maintains airfield lighting, transmission systems, power plants, interior wiring, and lighting systems, and locates and splices cable faults.

Core Skills

  • Airfield lighting installation and maintenance
  • Cable fault location and splicing
  • Electrical power plant operation and maintenance
  • Component-level electrical troubleshooting

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.

Electricians

Planning and installing interior wiring and lighting, splicing cables, and troubleshooting electrical components directly overlap with civilian electrical installation and repair.

How to prepare: Submit your military electrical training and experience records to an apprenticeship sponsor for assessment toward a typically 4- or 5-year apprenticeship; shortened training depends on experience and testing. Entry requires a high school diploma or equivalent, apprenticeship requirements vary by state and locality, and most states require an examination and license, with independent journey-level work subject to local or state licensing requirements.

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.

Hydroelectric Plant Technicians

Operating and maintaining military electrical power plants provides a foundation for monitoring generating equipment and addressing plant malfunctions.

How to prepare: Take hydroelectric operations training focused on turbines, water-control equipment, and generating-unit start and stop procedures to bridge from electrical power plant experience.

What the civilian work involves
  • Monitor hydroelectric power plant equipment operation and performance, adjusting to performance specifications, as necessary.
  • Identify or address malfunctions of hydroelectric plant operational equipment, such as generators, transformers, or turbines.
  • Start, adjust, or stop generating units, operating valves, gates, or auxiliary equipment in hydroelectric power generating plants.
Civilian tools and software (examples)
  • Computerized maintenance management system CMMS
  • Distributed control system DCS
  • Supervisory control and data acquisition SCADA software

Notes & Sources

  • Electricians may need continuing education to maintain their licenses.
