An Electrician Senior is the advanced level of electrical work installing, repairing, testing and maintaining complex electrical systems including high-voltage service (13,000 volts or more), equipment, fixtures, and control devices.  Employees in this classification do not supervise other positions but may provide guidance and direction to lower-level Electricians, semi-skilled or unskilled maintenance workers.

Employees in this classification receive general supervision from a maintenance supervisor or other supervisory position.  Employees may be subject to call-in on a 24- hour basis.  The work may be performed in extremes of heat and cold and employees may be exposed to noisy, dirty and uncomfortable conditions.  The work may require the use of protective equipment such as safety goggles, face shields and gloves when drilling into metal, masonry or concrete; masks and respirators when working around asbestos; and insulated rubber gloves and sleeves when working around high voltage lines.  The work may require working in confined spaces at different heights and moving objects in excess of 50 pounds.
