Electrical Equipment Repairing
TS-72 April 1994
WORK COVERED

This standard is for grading nonsupervisory jobs involved in troubleshooting, testing, installing,
repairing, overhauling, modifying, and maintaining electrical devices, equipment, and
components such as automatic alternator synchronizing equipment, amplidyne control units,
voltage regulating equipment, generators, actuators, switching and control panels, junction
boxes, AC and DC motors, electrical harnesses, transformers, and power amplifiers. Typically,
the equipment and components serviced have been removed from aircraft, ships, ground support
or industrial equipment, tracked or wheeled heavy duty vehicles, missiles, etc. The work
requires knowledge of electrical circuitry, formulas, and principles and their application to the
devices, equipment, components, and systems repaired. In addition, some work may require
knowledge of electronic circuitry and theory and general mechanical skills and knowledge.

This standard cancels and supersedes the Job Grading Standard for Electrical Equipment
Repairer, 2854, issued in August 1974.

WORK NOT COVERED

This standard does not cover work that primarily involves:

- Work involved in installing, maintaining, troubleshooting, and repairing electrical wiring
systems and associated fixtures, controls, and equipment in industrial, institutional,
office, and residential buildings, and on ships. (See
Job Grading Standard for Electrician
Series, 2805
.)

- Work involved in installing, maintaining, troubleshooting, overhauling, and repairing aircraft
electrical systems and equipment on board aircraft. (See
Job Grading Standard for
Aircraft Electrician Series, 2892
.)

- Work involved in installing, maintaining, troubleshooting, overhauling, and repairing
electronic systems and equipment. (See
Job Grading Standard for Electronics Mechanic
Series, 2604
.)

- Work involved in installing, maintaining, testing, and repairing an electrical power plant or
overhead and underground primary electrical distribution systems. (See
Job Grading
Standard for High Voltage Electrician, 2810
.)

- Work involved in servicing custodial equipment such as waxing machines, vacuum cleaners,
power scrubbing machines, and wall washing machines. (See series definition for

Custodial Equipment Servicing, 4808
.)

- Work involved in maintaining, adjusting, sharpening, and repairing a variety of tools, safety
equipment, and portable power equipment such as hand-held electric power tools that are
issued from shop toolroom and equipment areas to production and maintenance workers.

TITLES

Jobs graded by this standard at grade 9 and above are titled Electrical Equipment Repairer.

Jobs graded by this standard below grade 9 (other than helper and intermediate jobs) are titled
Electrical Equipment Worker.

GRADE LEVELS

This standard does not describe all possible grades at which jobs might be classified. If jobs
differ substantially from the skills, knowledge, or other work requirements described in the
standard, they may be graded either above or below the grade levels described based on sound
job grading methods.

HELPER AND INTERMEDIATE JOBS

Helper jobs are graded by the Office of Personnel Management
Job Grading Standard for Trades
Helper Jobs
.

The grade 7 level described in this standard DOES NOT apply to jobs that are part of a planned
program of training and development of skills for advancement to a higher grade. Such trainee
jobs are covered by the Office of Personnel Management "
Job Grading Standard for Intermediate
Jobs
." Grade 9 in this standard is to be used as the "full performance" level or grade in applying
the Intermediate Job Grading Table.

NOTES TO USERS

Ongoing technological advancements in the field of electronics have had and will continue to
have an impact upon electrical components and devices commonly found in electrical
equipment. As a consequence, work within this occupation, in certain work situations, may
require knowledge of electronic principles ranging from a practical understanding to a
knowledge of general electronic theory. For example, when electro-mechanical controls have
been superseded by electronic technology, often the electronic-based devices are so limited in
scope of operation and complexity of design that adjustment and repair can be done in
accordance with detailed instructions for which little electronics knowledge is required.
Typically such work would be graded by the
Job Grading Standard for Electronics Mechanic,
2604
, at or below grade 8. In other cases, the overall complexity of the unit may be greater, but
the electronics knowledge generally does not exceed the grade 10 level as described in the
Electronics Mechanic standard. That is, the electronic devices worked on are generally a part of
a self-contained and functionally independent unit that would not exceed the complexity
described at the grade 10 level in that standard. In accordance with the
Federal Wage System
mixed job (occupation/grade) job grading policy
, if both the electrical and electronics work are at
the same grade and the electrical work is paramount, the job would continue to be classified to
U.S. Office of Personnel Management

TS-72 April 1994
the 2854 or other appropriate nonelectronics series. Only when electronics knowledge is
paramount and/or the work involves installing, troubleshooting, maintaining, and repairing
electronics equipment and complete operational systems of the complexity described at grade 11
level in the
2604
or other appropriate electronics standard, should it be placed in an appropriate
electronics series.

For a detailed discussion of the impact of technological development in electronics and a
discussion of computer-controlled automatic test equipment (ATE), refer to the

ELECTRICAL EQUIPMENT REPAIRING, GRADE 7

General
: Grade 7 electrical equipment workers apply established work methods and
procedures to perform limited diagnostic checks and to disassemble, repair, reassemble, and test
electrical equipment and components that have been removed from ground support or industrial
equipment, tracked or wheeled heavy duty vehicles, missiles, aircraft, ships, etc. Many of the
components serviced at this level may be more mechanical than electrical and contain only a few
switches and wires. Following prescribed procedures, they disassemble equipment such as
motors and generators and make electrical and mechanical repairs by replacing or adjusting parts
such as coils, armatures, bearings, switches, wiring or insulation, and gears. They assemble,
repair, modify, replace, and install electrical quick change assembly components such as
electrical cables and wiring harnesses associated with engine and transmission components and
test the completed products. They use a variety of test equipment such as voltmeters,
ohmmeters, multimeters, growlers, meggers, and specialized test sets to test for shorts,
continuity, and defective wiring and connections. They use standard hand tools and micrometers
to check for extensive wear of bushings, bearings, and gears. They assist higher grade workers
on assignments involving equipment and components of greater complexity than those described
above by performing discrete tasks such as routine disassembling, repairing, and reassembling
the simpler components and then bench testing them.

Skill and knowledge
: Grade 7 electrical equipment workers have a practical knowledge of
electrical and mechanical principles, and familiarity with pneumatic and hydraulic trade
practices. They know how to locate and repair malfunctions and test completed work. They
apply knowledge of wire color codes, symbols, layout sheets, wiring diagrams, schematics,
technical orders, and manufacturers' specifications to complete assignments. They require a
working knowledge of various types and sizes of wires, connectors, and plugs.

Electrical equipment workers at this level use mechanical skills to replace and adjust bearings,
brushes, coils, and gears in completing repairs. They are skilled in the operation of common
electrical test devices such as ohmmeters, voltmeters, growlers, and meggers to perform ba
