Duties

Electrical and electronics installers and repairers typically do the following:

  • Prepare cost estimates for clients
  • Refer to service guides, schematics, and manufacturer specifications
  • Repair or replace defective parts, such as motors, fuses, or gaskets
  • Reassemble and test equipment after repairs
  • Maintain records of parts used, labor time, and final charges

Modern manufacturing plants and transportation systems use a large amount of electrical and electronics equipment, from assembly line motors to sonar systems. Electrical and electronics installers and repairers fix and maintain these complex pieces of equipment.

Because automated electronic control systems are becoming more complex, repairers use software programs and testing equipment to diagnose malfunctions. Among their diagnostic tools are multimeters - which measure voltage, current, and resistance - and advanced multimeters, which measure the capacitance, inductance, and current gain of transistors.

Repairers also use signal generators, which provide test signals, and oscilloscopes, which display signals graphically. In addition, repairers often use hand tools such as pliers, screwdrivers, and wrenches to replace faulty parts and adjust equipment.

The following are examples of types of electrical and electronics installers and repairers:

Commercial and industrial electrical and electronics equipment repairers adjust, test, repair, or install electronic equipment, such as industrial controls, transmitters, and antennas.

Electrical and electronics installers and repairers of transportation equipment install, adjust, or maintain mobile communication equipment, including sound, sonar, security, navigation, and surveillance systems on trains, watercraft, or other vehicles.

Powerhouse, substation, and relay electrical and electronics repairers inspect, test, maintain, or repair electrical equipment used in generating stations, substations, and in-service relays. These workers also may be known as powerhouse electricians, relay technicians, or power transformer repairers.

Electric motor, power tool, and related repairerssuch as armature winders, generator mechanics, and electric golf cart repairers - specialize in installing, maintaining, and repairing electric motors, wiring, or switches.

Electronic equipment installers and repairers of motor vehicles install, diagnose, and repair sound, security, and navigation equipment in motor vehicles. These installers and repairers work with a range of complex electronic equipment, including digital audio and video players, navigation systems, and passive and active security systems.

Electrical and electronics installers and repairers may also specialize, according to how and where they work:

Field technicians often travel to factories or a customer's site to repair broken down equipment. Because repairing components is a complex activity, workers usually remove and replace defective units, such as circuit boards, instead of fixing them. Defective units are discarded or returned to the manufacturer or a specialized shop for repair.

Bench technicians work in repair shops in factories and service centers, fixing components that cannot be repaired on a factory floor. These workers also locate and repair circuit defects, such as poorly soldered joints, blown fuses, or malfunctioning transistors.
