Electrical and Electronics Installers and Repairers

Electrical and Electronics Installers and Repairers typically perform the following tasks: • 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. • Repair and rebuild defective mechanical parts in electric motors, generators, and related equipment, using hand tools and power tools. • Lift units or parts such as motors or generators, using cranes or chain hoists, or signal crane operators to lift heavy parts or subassemblies. • Record repairs required, parts used, and labor time. • Disassemble defective equipment so that repairs can be made, using hand tools. • Adjust working parts, such as fan belts, contacts, and springs, using hand tools and gauges. • Lubricate moving parts. • Read service guides to find information needed to perform repairs. • Inspect electrical connections, wiring, relays, charging resistance boxes, and storage batteries, following wiring diagrams. • Scrape and clean units or parts, using cleaning solvents and equipment such as buffing wheels. • Weld, braze, or solder electrical connections. • Verify and adjust alignments and dimensions of parts, using gauges and tracing lathes. • Steam-clean polishing and buffing wheels to remove abrasives and bonding materials, and spray, brush, or recoat surfaces as necessary. • Set machinery for proper performance, using computers. • Test equipment for overheating, using speed gauges and thermometers. • Reface, ream, and polish commutators and machine parts to specified tolerances, using machine tools. • Maintain stocks of parts. • Cut and form insulation, and insert insulation into armature, rotor, or stator slots.
