Open Book Test

The Washington DC Master Electrician examination is an open book test. The 2011 National Electrical Code and Ugly's Electrical References are identified as approved references for the exam.

An open book examination still requires thorough preparation. Candidates have a limited amount of time to answer 100 questions, so searching through a reference from the beginning for every answer is not an efficient strategy. Candidates should become familiar with NEC organization, article numbering, important tables, definitions, chapter structure, exceptions, and cross-references before the examination.

The highlighted and tabbed format helps support that preparation. Tabs provide recognizable navigation points for frequently referenced areas, while highlighting helps emphasize important material during repeated study. The goal is to reduce unnecessary searching and make it easier to return to key information when working through practice questions.

During preparation, practice identifying the subject of a question before opening the NEC. Decide whether the question concerns services, feeders, branch circuits, grounding, wiring methods, equipment, motors, or another category. From there, move to the appropriate NEC article and locate the specific section or table that controls the answer.

Ugly's Electrical References can also support preparation in areas involving formulas, electrical theory, calculations, conversions, conductor information, transformers, motors, and other commonly used electrical data. Knowing which reference is best suited for a particular type of question can help candidates use their exam time more effectively.

Test Information and Study Materials

General Knowledge and Plan Reading: Review electrical principles, terminology, symbols, plans, specifications, and the ability to interpret information presented in electrical drawings. Master Electrician candidates should be comfortable moving between practical trade knowledge and code requirements.

Services and Service Equipment: This category represents 16% of the published examination outline. Study service conductors, service equipment, disconnecting means, overcurrent considerations, service calculations, installation requirements, and related NEC provisions.

Feeders: Review feeder conductor requirements, ampacity, load calculations, overcurrent protection, and applicable installation provisions. Although feeders represent a smaller percentage of the exam, they remain part of the published outline.

Branch Circuits and Conductors: Another 16% of the exam focuses on branch circuits and conductors. Candidates should review branch-circuit requirements, conductor ampacity, conductor sizing, insulation, temperature limitations, adjustment factors, correction factors, and related protection requirements.

Wiring Methods and Materials: At 19%, this is the largest individual examination category. Study raceways, cables, boxes, fittings, conductor installation, permitted uses, installation restrictions, raceway fill, box fill, and other wiring-method requirements.

Equipment and Devices: Review electrical equipment requirements, device applications, installation rules, and code provisions related to commonly installed electrical equipment.

Control Devices: Candidates should understand the basic operation and application of electrical control devices and know where applicable NEC requirements can be found.

Motors and Generators: Review motor conductor sizing, overload protection, short-circuit and ground-fault protection, disconnecting means, controller requirements, generator provisions, and associated calculations.

Special Occupancies, Equipment, and Conditions: Study the NEC chapters covering installations that require rules beyond general wiring requirements. Candidates should practice recognizing when a question involves a special occupancy, special piece of equipment, or special condition so they can move to the correct NEC article efficiently.

A productive study strategy combines code navigation with practice-oriented review. Instead of only reading the NEC from beginning to end, select a subject from the examination outline and answer questions that require you to locate the applicable code section. Use the tabs to reach the appropriate part of the book, then read enough surrounding language to understand the full requirement.

Calculations should also be practiced separately. Work through service, feeder, conductor, motor, and other electrical calculations while becoming comfortable with the formulas and tables involved. Ugly's Electrical References can be useful when reviewing commonly used formulas and electrical data.
