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.

Overview

A mobile electric power plants intermediate maintenance technician performs on-equipment repairs and intermediate maintenance on mobile electric power plants. The technician troubleshoots and repairs motors, generators, voltage and frequency control systems, fault indicators, rectifiers, oscillators, magnetic amplifiers, and related control circuits.

Core Skills

Voltage regulation and protection circuit troubleshooting
Frequency control and fault indicator repair
Rectifier, oscillator, and magnetic amplifier repair

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

Troubleshooting and repairing MEPP electric motors, generators, and control circuits transfers directly to motor and generator repair work.

How to prepare: Arrange supervised shop practice in motor disassembly, mechanical rebuilding, and reassembly to specified ratings to complement your electrical troubleshooting experience.

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.
Reassemble repaired electric motors to specified requirements and ratings, using hand tools and electrical meters.
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.

Power Plant Operators

MEPP generator maintenance and troubleshooting of voltage, frequency, and fault indicator systems provide a foundation for monitoring generating equipment and recognizing operating problems.

How to prepare: Seek an operator-trainee program with supervised practice in generator output matching and plant startup and shutdown procedures to bridge from equipment repair to plant operation.

What the civilian work involves

Control generator output to match the phase, frequency, or voltage of electricity supplied to panels.
Monitor power plant equipment and indicators to detect evidence of operating problems.
Start or stop generators, auxiliary pumping equipment, turbines, or other power plant equipment as necessary.
