The scale of these drawings ranges from millions of transistors on a small wafer of silicon to power distribution systems which span whole provinces. (4)
  • Scan electrical and electronic schematics to identify devices in circuits, understand how circuits operate and locate information such as voltages, polarities and component values. For example, electrical engineers may scan schematic diagrams of distributed control systems in manufacturing plants when planning modifications. The schematics show how the thousands of sensors and control elements are connected to central control system boards. The electrical and electronic schematics are often selected and viewed in relation to other documents such as manufacturing process flow charts or scale drawings of the plants. (4)
  • Use the information from documents found in lengthy technical reports and specification documents when evaluating, planning and improving electrical and electronic systems. These documents include complex tables, schedules, graphs, scale drawings, assembly drawings and schematics that detail and describe electrical, communication, manufacturing and processing systems. For example, engineers may select and analyze the most relevant information from tables with pictures, lists and characteristics of equipment and many pages of electrical schematics in order to analyze the results of reliability studies of electrical power systems and determine the need for corrective actions. (5)

Measurement and Calculation Math
  • Calculate the dimensions of buildings, equipment and components from scale drawings. For example, they may check architectural drawings to make sure rooms are large enough to accommodate electrical and electronic equipment. (2)
  • Set up, configure, calibrate and use specialized measuring equipment. For example, they may use vision systems to take precise measurements of moving equipment or oscilloscopes to measure voltages and frequencies in electrical circuits. (3)
  • Use advanced mathematics such as trigonometry and calculus to plot or describe waveforms as part of circuit design processes. (4)
  • Use a wide variety of electrical and electronic formulae. For example, they may calculate the inductance of coils in millihenries using an equation which relates inductance to coil radius, and length and the number of turns of wire in the coil. (4)
  • Use advanced mathematical methods, including modelling, to analyze complex electrical or electronic systems. For example, they may calculate the power required to meet the forecasted demand in given regions and determine the quantities and types of equipment required to produce it, or they may calculate the optimal flow of robotic function between equipment, machinery, conveyors and people to enhance production in rubber tire plants. (5)
Data Analysis Math
  • Describe complex electrical and electronic systems statistically to analyze the effects of system or environmental changes. For example, they may analyze pulp production data to find out when pulp mills started and stopped making pulp to determine if the stoppages are insurable claims. The data are presented as complex graphs which indicate trends in chip meter speed and the number of cooked wood chips produced. (3)
  • Analyze data to monitor industrial processes. For example, they may compare the speeds of equipment to desired standards to decide if motors need to run faster or they may conduct protection coordination studies to describe the performance of circuit breakers in industrial facilities. (4)

(3)
  • May estimate the demand placed on power grids, computer networks and phone systems. They analyze past trends and factor in other variables such as the introduction of new service to plan budgets for manufacturing processes and power generation projects worth several million dollars. (1)
Oral communication Help - Oral communication
  • Interact with co-workers, colleagues and suppliers to gather information, access subject matter expertise, brainstorm solutions, coordinate work and receive feedback on recommendations. For example, they may speak with electrical technologists and technicians about aspects of project implementation or interact with suppliers to find about the electrical equipment available for projects. (2)
  • Participate in group discussions. For example, at the end of projects they meet engineering team members to share experiences, review successes, plan for the future and note areas for improvement. (2)
  • Interact with clients to identify needs and to sell products, services or engineering solutions. Electrical and electronics engineers must ask the right questions and listen carefully to ensure that proposed solutions meet clients' needs. (3)
  • Make presentations to clients, colleagues and managers. For example, they make presentations to small client groups outlining proposed solutions to technical needs; to other engineers and professionals with whom they work to brief them on technical matters; and to management to justify investments in proposed projects. Presentations vary in length from fifteen minutes to several hours and include visual presentations, handouts and question and answer periods. (3)
  • May participate in national and international committees which develop and update standards. They may sit on standards committees organized by the Standards Council of Canada, the National Fire Protection Association, the Canadian Standards Association and the Underwriter's Laboratories of Canada. (4)
Thinking Help - Thinking Problem Solving
  • Encounter capacity problems in power, communications and information technology systems. For example, they may find that the capacities of electrical substations are exceeded because the demand for electricity is too high. They collect data to identify immediate solutions such as moving power lines to neighbouring substations to meet the demand. (2)
  • Face construction delays and complications due to poor or inadequate planning. For example, electrical engineers in some contexts may find that units of street lighting systems cannot be installed as designed because their bases would be on top of underground sewer lines. They relocate the base units to avoid the sewer lines and change the positioning and aim of the lights to achieve the desired light intensity. They note the changes on construction drawings. The ability to quickly solve small construction problems is important to keep jobs on time and on budget. (2)
  • Have difficulty meeting project deadlines when unforeseen circumstances arise. When technical difficulties or insufficient resources delay projects, they consult with co-workers and colleagues to reassess project goals and discuss their options. They may reduce the scopes of projects or renegotiate new deadlines with clients so that all planned activities can be completed. (2)
  • Discover errors in plans created by colleagues. For example, they may find that architectural floor plans for electrical and equipment rooms are too small to accommodate the required equipment. They consult with architects to ask them to rework the space. If additional space is not available, they may adapt space available elsewhere in the buildings. (3)
  • Have clients who do not accept their advice. For example, they may find that clients want to use inferior products to save money instead of the products they have recommended. They talk with the clients and point out why the recommended products are the only permissible options. Electrical and electronic engineers are guided by a code of ethics which must be followed at all times. (3)
  • Find that new equipment malfunctions. They may find that new industrial process equipment worth several million dollars does not work after being installed correctly. They check manuals to confirm that the equipment is set up properly and consult with colleagues, experts, help-line operators and equipment manufacturers to find the sources of faults. They conduct tests and engineering studies. They may also develop unique solutions to get the equipment working. (4)
  • Find that industrial operations and processes do not run well. For example, electrical engineers in food processing plants may discover that steam pressure readings in processing equipment are fluctuating inappropriately. The engineers work with instrument mechanics and plant operators to determine if pressure relief valve control systems are causing the problems or whether the plant steam loads are swinging. When the causes of the problems have been identified, the electrical engineers develop solutions to correct the fluctuations or reduce the effects. (4)
Decision Making
  • Decide not to authorize work which would be unsafe or environmentally damaging. For example, electrical engineers may insist that lighting be installed in parking lots for safety reasons even though clients do not support the added expense. (2)
  • Decide to temporarily stop projects when expenditures exceed organizational limits. For example, they may decide to halt projects and consult with top management to discuss causes, options and recommended actions when cost overruns exceed fifteen percent. (2)
  • Make decisions about equipment adjustment, repair and replacement. For example, electrical engineers in pulp and paper plants may decide to use variable speed drives to improve the pulp production process when the existing control valves wear out. They base their decisions on cost and reliability analyses for all replacement and repair options. Selecting the wrong equipment can reduce pulp production or cause injuries to production personnel. (3)
  • Decide which electrical codes, standards and guidelines apply when designing electrical systems for construction, manufacturing, processing and electrical generation projects. They consider the type, function and location of the projects to determine the guidelines that must be followed. Failing to follow required codes can result in unsafe electrical systems, work that has to be redone and the loss of the credibility for engineers and their organizations. (3)
  • Decide what equipment to buy or recommend for purchase for short-term or long-term projects. They follow established procedures and selection guidelines for equipment, considering costs and past experiences with similar equipment and similar installations. Selecting inappropriate equipment can result in safety concerns, lost productivity and financial loss for the clients' and the engineers' organizations. Decisions can only be reversed at significant cost, especially for larger equipment. (3)
Critical Thinking
  • Judge the validity and accuracy of contractors' claims for payment. They check to see if the claims are justified and, when the work itemized on claims seems beyond the terms of agreements, recommend that contractors' statements of work should be adjusted. (2)
  • Judge the suitability of equipment and systems. For example, they may evaluate suitability of programmable logic controllers when implementing new processes. They review the specifications for existing controllers in relation to the sequences of operations, temperatures and flows required for their particular applications. (3)
  • Evaluate the adequacy of intricate architectural and mechanical engineering plans which specify the planned interfaces between their respective systems. They use their specialized knowledge of electrical and electronic systems, experience and understanding of architecture and mechanical engineering to make the assessments. Errors in analysis can negatively affect projects, relationships with clients and the reputations of consulting firms and engineers. (3)
  • Evaluate the efficiency and ergonomics of manufacturing processes. For example, electrical and electronics engineers may assess the best way to design tire manufacturing processes. They assess how to get products in and out of the processes and how to arrange the work flow of robots moving tires through tight spaces. They consider tire flow, tracking requirements, safety, ergonomics of how operators interface with the machinery and the familiarity of maintenance staff with equipment. They must balance the need for operational efficiencies against safety concerns. Risks of poor judgement may include injuries, loss of production and increased costs to the companies as well as loss of credibility of the electrical and electronics engineers. (4)
  • Evaluate the reasonableness of clients' requests. They consider the need for the work, the feasibility of the work in terms of time and budget and the degree to which they think the work will satisfy clients' needs. They gather data by talking to clients, reviewing records and taking measurements. Electrical and electronics engineers usually lead the process of gathering data and developing consensus. Poor evaluation results in unsatisfactory projects and rejected proposals. (4)
  • Evaluate the completeness of electrical and electronic designs. For example, they approve and sign electrical and electronics schematics to indicate they will work and that they meet all required standards before they are forwarded to others for implementation. The schematics are complex illustrations of each of the proposed electrical systems. They include many features that must be checked for adherence to relevant codes such as the Canadian Electrical Code and the Institute of Electrical and Electronics Engineers Recommended Practices. Low quality, unsafe or unacceptable designs present risks and incur continuing costs until they are fixed. (4)
Job Task Planning and Organizing

Own Job Planning and Organizing

Electrical and electronics engineers set their own priorities and plan their daily work activities within the framework of project schedules and deadlines. They need to manage time effectively if they are to produce high quality work on time and within approved budgets. Their work is often interrupted by unpredictable factors such as last minute client changes and requests, equipment breakdowns and work delays caused by underestimation of project complexity, communication errors and many other factors that may interfere with expected results. They must be adept at revising schedules and priorities. They may log their consulting in fifteen minute segments to charge clients appropriately and to identify personal efficiency problems.
