Electrical Maintenance Worker 3 (High Voltage) Open

City of Cincinnati•Ohio 45202, OH

About The Position

This employee, in departments other than Traffic Engineering, performs Substation Maintenance Technician work on voltages up to 138,000 volts. The position may direct the work of others on difficult and complex electrical assignments, including high-voltage work. Duties involve advanced technical knowledge of electrical controls and complex devices, including layout, installation, maintenance, repair, replacement, adjustment, inspection, cleaning, testing, and troubleshooting of electrical and electromechanical systems and components. The employee troubleshoots electrical, hydraulic, and pneumatic controls and low-voltage control wiring on equipment and tools. Work may take place in buildings, grounds, shops, or the field, including confined spaces and locations at unusual heights. The role uses and analyzes thermography and works with Variable Frequency Drive units and equipment operating at 5,000 volts or more, including single- and three-phase wiring, machinery, distribution systems, switchgear, transformers, substations, control circuits, and related components. Related duties may be assigned. Applicants must have five years of full-time, paid electrical trade experience, including at least two years maintaining, installing, or troubleshooting medium-voltage equipment above 1,000 volts. Eligible electrical apprenticeship, high-school-level trade school, or accredited college-level electrical/electronic programs may substitute for one year of the five-year experience requirement, but not for the medium-voltage experience. A valid driver’s license is required; a commercial driver’s license may be required for some assignments. The role requires the ability to work with high voltage, in confined spaces, and at heights, as well as to handle heavy equipment and perform precise work. Depending on assignment, employees must be willing to work irregular, rotating, split, or night shifts and respond to emergency calls. Applicants must be U.S. citizens or hold a valid permanent resident card at appointment. A criminal background investigation is conducted.
