**This course is intended for students preparing for the Washington State Electrical Exam, and is not intended solely for continuing education credit. Please read through the COURSE INFORMATION AND EXPECTATIONS below prior to enrolling in this class.
Course Description:
- Day 1: The first day of this course focuses on essential calculation skills. Students will begin with a focused introduction to Power Law and Ohm’s Law, followed by hands-on instruction in applying Article 220 of the National Electrical Code (NEC) for basic dwelling unit load calculations. Emphasis will be placed on interpreting relevant NEC tables and practicing real-world problem-solving.
- Day 2: Building on the fundamentals covered in Day 1, the second day of this course prepares students for the more complex calculations found on the Washington State Electrical Exam. The class will begin with a brief review of Power and Ohm’s Law, and dwelling unit calculations, before progressing into commercial demand factors, Full Load Motor Current tables, overcurrent protection, and conductor ampacity considerations. Students will also work through detailed multi-family and commercial load calculation scenarios using the 2023 NEC.
To enhance exam performance, participants will receive guidance on effective test-taking methods and strategies, allowing attendees to assess their knowledge and identify areas for improvement.
All participants will receive supplemental materials—including handouts, practice exams, diagrams, examples, and worksheets—that may be brought into the exam.
