WORK PROCESS SCHEDULE
ELECTRICAL TECHNICIAN
O*NET/SOC CODE: 17-3023.00 RAPIDS CODE: 0155
DESCRIPTION: Applies electrical theory and related knowledge to test and modify developmental or operational electrical machinery and electrical control equipment and circuitry in industrial or commercial plants and laboratories: Assembles and tests experimental motor-control devices, switch panels, transformers, generator windings, solenoids, and other electrical equipment and components according to engineering data and knowledge of electrical principles. Modifies electrical prototypes to correct functional deviations under direction of ELECTRICAL ENGINEER. Diagnoses cause of electrical or mechanical malfunction or failure of operational equipment and perform preventative and corrective maintenance. Develops wiring diagrams, layout drawings, and engineering specifications for system or equipment modifications or expansion, and directs personnel performing routine installation and maintenance duties. Plans, directs, and records periodic electrical testing, and recommends or initiates modification or replacement of equipment which fails to meet acceptable operating standards.
ON-THE-JOB TRAINING:
The Electrical Technician apprentice program shall be considered completed when the apprentice has satisfactorily completed approximately 6 years of specified on-the-job training and related study, not to exceed 12,000 hours.
Under the supervision of a higher level technician, supervisor, or an electrical engineer, working from schematic and wiring diagrams, a description of the process being controlled, and/or a discussion of the operational problems occurring in the system, and upon the completion of the training, the technician trainee shall be capable of performing the following duties:
1. Make the necessary analysis to pinpoint the trouble area, and on small, less complex low-voltage systems take the necessary steps to isolate, locate, and correct the malfunction.
2. On more complex control systems involving high-cost equipment or where mandated equipment or high-voltage systems may be involved, perform analysis and study of the problem as in (1) above, but before proceeding with any corrections or energizing of equipment, must review entire problem with the supervisor and obtain further direction.
3. Select, install, and utilize the basic instruments necessary to pinpoint trouble areas in various control systems of limited complexity or to verify the performance of such properly operating systems.
4. Make analysis of system such as in (1) above to assure that the operation of all
components is within proper rating and to perform the necessary load study and
other calculations, as required.
5. Make up equipment or prepare sketches to have others make up devices, components, and hardware such as A.C. or D.C. power supplies, special panels, transformers, contactors, motor starters, etc. Also, may modify, alter, or adapt equipment as above to give predetermined operating characteristics. Work, such as described, is built up for systems, subsystems, and special equipment such as vacuum chambers, angle-of-attack devices, sting and Schlieren controllers, camera controls, instrumentation and recording devices, and other equipment.
6. Disconnect, disassemble, check-out, reassemble, or install precision electrical control devices and adapt and modify circuitry and electrical hardware and components to give desired and specified operating parameters.
