The four-hour examination provides an average of three minutes per question. Efficient code navigation and accurate interpretation are important preparation skills.

Open Book Test

The Missouri (Springfield) ICC Journeyman Electrician W17-MO-S examination is an open book test.

The published reference list identifies the 2017 National Electrical Code as the primary examination reference. Ugly's Electrical References, in any edition, is an allowed supporting reference.

Although reference materials are available during the examination, candidates must still understand the technical subjects being tested. Searching the NEC for every answer without prior preparation can consume valuable examination time.

Effective open-book preparation includes:

  • Learning how NEC chapters, articles, parts, and sections are organized.
  • Becoming familiar with Article 100 definitions.
  • Practicing how to locate branch-circuit and feeder requirements.
  • Reviewing conductor ampacity tables and their application.
  • Developing familiarity with grounding and bonding requirements.
  • Studying wiring methods and equipment installation provisions.
  • Practicing electrical calculations using familiar formulas.
  • Reading code exceptions and table notes carefully.
  • Developing a realistic question-by-question time-management strategy.

One useful method is to identify the key technical subject before opening a reference. For example, a question involving conductor ampacity may lead you toward conductor requirements and applicable tables, while a question involving a motor circuit may require reviewing specialized motor provisions.

The objective is to understand the electrical requirement, recognize the applicable installation conditions, and use the correct reference efficiently.
