With 210 minutes for 70 scored questions, candidates have an average of three minutes per question. Efficient NEC navigation and a strong understanding of electrical fundamentals can help you manage that time effectively.

Open Book Test

The Maryland Journeyperson Electrician (PSI) examination is an open book test. Candidates may use the approved National Electrical Code, 2020 Edition, during the examination.

The 2020 NEC is the only reference book permitted in the examination room. PSI does not supply this reference at the testing center.

The examination provider permits highlighting, underlining, and permanent indexing tabs in the approved code book. Handwritten notes, loose papers, attached materials, removable tabs, and study guides are not permitted.

Effective open-book preparation involves developing familiarity with NEC organization and understanding how different code articles relate to electrical installations.

Helpful preparation strategies include:

  • Learning the structure of NEC chapters, articles, sections, and tables.
  • Practicing the use of the NEC index and definitions.
  • Reviewing grounding, bonding, and overcurrent protection requirements.
  • Studying conductor ampacity and wiring methods.
  • Understanding branch-circuit, feeder, and service requirements.
  • Practicing electrical calculations and circuit relationships.
  • Recognizing equipment-specific installation requirements.
  • Developing efficient time-management habits.

An open-book examination still requires electrical understanding. Recognizing the subject of a question before consulting the code helps reduce unnecessary searching and supports more efficient problem-solving.

State licensing supports professional accountability and provides a regulated framework for qualified individuals performing electrical installations.

Reference Books

  • National Electrical Code (NEC), 2020 Edition
    Published by the National Fire Protection Association as NFPA 70, the 2020 National Electrical Code establishes technical requirements for electrical installations. It addresses wiring methods, conductor sizing, branch circuits, feeders, services, overcurrent protection, grounding and bonding, motors, controllers, special occupancies, equipment, and communication systems. The 2020 NEC is the approved reference for the Maryland PSI Journeyperson Electrician examination.

The National Electrical Code provides an essential framework for understanding electrical installations and technical requirements.

Important study areas include Article 100 for definitions, Article 110 for general installation requirements, Article 210 for branch circuits, Article 230 for services, Article 240 for overcurrent protection, Article 250 for grounding and bonding, Article 300 for wiring methods, and Article 310 for conductors.

Become familiar with the organization of these provisions and how they relate to practical electrical work.

Studying the NEC alongside online practice questions can help improve both technical understanding and reference-navigation skills.
