Job Task Planning and Organizing
  • Assemblers, fabricators and inspectors, industrial electrical motors and transformers have some variety in their work activities as they work with different types and models of industrial electrical equipment. Their work priorities and deadlines are set by leadhands and supervisors who give them assignments at the beginning of each shift. Within this framework, they have considerable scope to plan and organize their job tasks and the choices made in this regard greatly impact efficiency. They co-ordinate their work plans with co-workers to schedule access to shared tools and equipment. Inspectors co-ordinate their work plans with assemblers and electrical fitters and wirers to monitor production and perform quality control inspections. The day's work plan is often disrupted by mechanical and quality problems which must be resolved immediately. (3)

Decision Making
  • Decide how to label wires in a panel so that others may easily interpret the system, based on its logic. (1)
  • Decide which of several available methods will be used to repair motors considering such factors as the customers' budget and return deadline, availability of parts and tools and quality control standards. (2)
  • Decide whether to hold, ship or reject completed electric motors, transformers or control equipment based on whether they are in conformance with quality control standards. (3)

Problem Solving
  • The wrong part is listed on the schematic drawing. Determine whether you have sufficient background knowledge and experience to identify the correct part and proceed with the work, consulting co-workers or an engineer if additional expertise is required. (1)
  • There are production problems resulting from recurring shortages of lug bolts and related difficulties in finding comparable replacement bolts. It may be necessary to prepare and post an information board, showing samples of all lugs and the corresponding replacement part numbers, to provide assemblers and engineers with easy access to information. (2)
  • There is some difficulty in determining the root cause of motor failures. Find as much information as possible about the motor, by conferring with co-workers and looking up information in manuals and books, before performing various tests in a systematic fashion to diagnose the technical problem. (2)
  • It is evident that the design parameters outlined by the engineering department mean that the item won't fit in the assembly. Adapt the design by modifying the coil or making a new tank, ensuring that this doesn't modify the technical integrity of the equipment. (3)

Finding Information
  • Refer to a sequence of operations sheet to obtain assembly instructions. (1)
  • Speak with co-workers and the supervisor to find information on how to troubleshoot problems. (2)
  • Refer to schematic drawings to find electrical information about a motor or transformer. (2)
