Electrical Power Distribution: Part 2 - Drawings, Symbols & Studies

Oct 23, 2026

Uploaded by Asher

This SunCam online continuing education course trains learners to read electrical engineering drawings and interpret the symbols, notes, and information used in project development, construction, and system maintenance. It introduces major drawing types including single-line diagrams, three-line drawings, riser diagrams, schematics, wiring diagrams, and schedules, then explains common electrical power system studies. Short circuit, coordination, arc flash, and load flow studies are covered with their purposes and typical outcomes.

Types of electrical engineering drawings used in project development, construction, and system maintenance 2. Information that can be found on electrical engineering drawings 3. Symbols and notes used on electrical engineering drawings 4. Types of electrical engineering studies, their purposes and uses Introduction Engineering documentation comes in many forms such as plans, drawings, specifications, data sheets, brochures, data sheets, and the results of engineering studies. This course is an introduction to the information that is commonly found on electrical engineering drawings, the symbols used to represent the equipment, and the information and purposes of some of the more common electrical engineering studies. As an introductory-level course, it is good to be aware of the organizations that influence and govern codes and standards for the design, installation, and use of electrical equipment. Following is a list of organizations and institutions engaged in setting standards and codes that govern the design, manufacturing, installation, and/or testing of electrical equipment. The codes and standards from these organizations are commonly referenced on electrical engineering plans and specifications. IEEE – The Institute of Electrical and Electronic Engineers is a non-profit professional association. The IEEE produces a wide range of publications which include consensus-based standards. ANSI – The American National Standards Institute oversees standards and conformity assessment activities in the United States. ANSI facilitates and promotes voluntary consensus standards, conformity assessment systems, and safeguards their integrity. Electrical Power Distribution: Part 2 – Drawings, Symbols & Studies A SunCam online continuing education course 469.pdf IEC – The International Electrotechnical Commission is an international organization which publishes standards for electrical equipment. NEMA – The National Electrical Manufacturers Association establishes standards for the operating performance, characteristics, construction and testing of equipment to ensure standardization of electrical equipment. NFPA – The National Fire Protection Association is a global nonprofit organization devoted to eliminating death, injury, and property or economic loss due to fire, electrical and related hazards. They deliver information and knowledge through more than 300 consensus codes and standards, research, training, education, outreach, and advocacy. NFPA 70 – One of the codes published by the NFPA and is the benchmark for safe electrical design, installation, and inspection to protect people and property from electrical hazards. This is also known as the National Electric Code. NFPA 70E – One of the codes published by the NFPA that establishes requirements for safe work practices to protect personnel by reducing exposure to major electrical hazards. Originally developed at OSHA's request, NFPA 70E helps companies and employees avoid workplace injuries and fatalities due to shock, electrocution, arc flas

FAQs

What learning objectives does the course cover?
