Overview

An LSD 41/49 Class Electric Plant Maintainer performs organizational level preventive and corrective maintenance, system alignment, troubleshooting, and fault isolation within the electric plant. This maintainer follows technical manuals and Engineering Operational Sequencing System procedures to maintain the system with little or no intermediate or depot level assistance.

Core Skills

  • Electric plant troubleshooting and fault isolation
  • System alignment using sequenced operating procedures
  • Plant maintenance with limited depot support

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.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Electric plant preventive and corrective maintenance, troubleshooting, and fault isolation transfer directly to diagnosing and repairing industrial electrical equipment.

How to prepare: Build a troubleshooting work sample from a non-sensitive maintenance example, showing the fault symptoms, technical-manual checks, corrective action, and verification of proper operation.

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

Hydroelectric Plant Technicians

Shipboard electric plant fault isolation and procedure-based system alignment provide a foundation for addressing equipment malfunctions and adjusting plant performance in hydroelectric facilities.

How to prepare: Take introductory hydroelectric operations training that covers generating-unit controls, valves, gates, and auxiliary equipment to address the plant-specific operations gap.

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
