Why Every Electrician Should Know Ugly's Electrical References

Ugly’s Electrical References has been a trusted companion for electricians, apprentices, and engineers for decades. Here’s why it is invaluable for those preparing for the NEC exam:

1. Quick Access to Essential Information

The book provides a concise, easy-to-use format that helps electricians quickly find key formulas, wire sizing charts, conduit fill tables, and motor calculations. This efficiency is critical in an exam setting where time management can make or break your success.

2. Simplifies Complex Electrical Concepts

Instead of sifting through the NEC codebook’s extensive text, Ugly’s distills complex information into charts, diagrams, and quick-reference tables, making it easier to understand and apply during the exam.

3. Enhances NEC Code Familiarity

Although Ugly’s Electrical References is not a substitute for the NEC codebook, it complements it by summarizing key electrical codes and calculations in a practical, user-friendly manner. Frequent use of Ugly’s helps test-takers retain and recall critical NEC concepts faster.

4. Improves Exam Navigation Skills

Because the NEC exam is open-book, success depends on how well candidates navigate reference materials. Practicing with Ugly’s before the test helps develop efficient lookup skills, reducing time spent searching for answers during the exam.

Ugly’s Electrical References excels in this high-pressure environment for several reasons:

Its compact size (typically around 200 pages) makes it significantly faster to navigate than the complete NEC book
Information is logically organized with a detailed table of contents and index
Color-coded sections allow for quick reference during the exam
Essential tables, formulas, and diagrams are presented in a clear, easy-to-read format

Key Electrical Codes and Information Covered in Ugly's

NEC Code References and Interpretations

While Ugly’s Electrical References is not a substitute for the complete NEC, it effectively summarizes many of the most frequently referenced code sections, particularly those likely to appear on licensing exams. Some of the important NEC content you’ll find includes:

Article 110 – Requirements for Electrical Installations

Article 250 – Grounding and Bonding
Article 300 – Wiring Methods
Article 430 – Motors, Motor Circuits, and Controllers

The guide presents these complex code requirements in simplified, accessible language while still maintaining technical accuracy.

Essential Tables and Calculations

Perhaps the most valuable aspect of Ugly’s for exam purposes is its collection of tables that would otherwise require extensive searching in the NEC. These include:

Conductor ampacity tables with correction factors
Voltage drop calculations and tables
Conduit fill tables
Box fill calculations
Motor full-load current tables
Transformer calculations
Service and feeder load calculations

These tables are frequently referenced in exam questions, and having them readily accessible in Ugly’s can save crucial time.

Electrical Formulas and Applications

Ugly’s excels at providing practical applications of electrical formulas, including:

Three-phase power calculations
Power factor correction
Transformer sizing
Motor circuit design
Voltage drop calculations
Conduit bending calculations
Raceway fill calculations

The guide not only provides these formulas but also shows examples of how to apply them correctly, which is invaluable for the application-based questions common on the NEC exam.

ICC Exams That Use Ugly’s Electrical References

Several International Code Council (ICC) exams include Ugly’s Electrical References as an approved reference book. Understanding this resource is crucial for candidates pursuing electrical and building-related certifications. Some of these exams include:
