This handbook provides practical, application-focused examples for electrical engineers. Each chapter is structured with a Use Case → Calculation Steps → Schedule → Standards format. Appendices provide ready-reference tables, symbols, acronyms, and checklists.

This handbook is designed as a practical, application-driven reference for electrical engineers, designers, and students. Instead of presenting abstract theory, each chapter focuses on a real-world use case. Calculations are explained step by step, schedules are provided where applicable, and references to electrical codes and standards are included.
This structure ensures that readers can quickly apply engineering principles to actual design problems, while also staying compliant with codes such as the NEC (National Electrical Code), IEC standards, and other relevant regulations.

This book has been prepared by the Practicing Engineers Network, a collective of professionals with several years of hands-on experience in electrical design, installation, and code compliance. The Network brings together licensed engineers, project managers, and field practitioners who have not only designed and overseen large-scale power distribution systems, but also trained aspiring engineers for professional licensure exams.

Members of the Practicing Engineers Network have worked across diverse sectors—commercial, industrial, and utility power systems—giving them a comprehensive understanding of the challenges engineers face both in practice and during exam preparation. Their collective expertise ensures that the content is not only accurate and aligned with the latest exam specifications, but also enriched with practical insights, problem-solving strategies, and real-world examples.

The goal of the Practicing Engineers Network is simple: to empower future Professional Engineers with the knowledge, confidence, and tools needed to pass the PE Electrical and Computer: Power Exam on the first attempt, while also fostering a deeper understanding of engineering concepts that will serve them throughout their careers.
