CITS Electrician (Theory) study guide
CITS Electrician (Theory) · Work through your exam, one topic at a time.
The CITS Electrician (Theory) examination is a knowledge-based assessment for electricians and electrical trainees who need to demonstrate that they understand the principles behind the work they perform in the field. It suits apprentices preparing for advancement, experienced tradespeople seeking formal recognition, and technicians moving into roles where documented electrical knowledge is expected. The CITS Electrician (Theory) study guide has 8 sections and about 1,930 words.
01Electrical Safety and Codes
This domain tests how you recognize electrical hazards, apply safe work procedures, and use code requirements as design and inspection criteria rather than memorized trivia. Expect questions on isolation, arc-flash and shock risk, bonding, clearances, and protective devices.
280 words, about 1 min02Electrical Theory and Fundamentals
This domain tests Ohm’s law, power relationships, series and parallel circuits, AC impedance, power factor, three-phase quantities, transformers, and basic machines. Questions often require selecting the right formula and keeping units consistent.
238 words, about 1 min03Wiring Methods and Materials
This domain tests conductor selection, insulation and temperature ratings, ampacity, derating, raceway and box fill, support, bending, connectors, and suitability for wet, damp, or hazardous locations. The exam expects code-based method selection, not just “it fits.” Start with the conductor ampacity from the applicable table, then apply ambient-temperature correction and conductor-adjustment factors.
247 words, about 1 min04Installation and Maintenance
This domain tests planned installation, mechanical integrity, correct terminations, clearances, preventive maintenance, and equipment condition assessment. The focus is on work that remains safe and reliable after commissioning.
229 words, about 1 min05Electrical Systems and Equipment
This domain tests distribution equipment, transformers, switchgear, motors, starters, variable-frequency drives, generators, UPS systems, protection coordination, and grounding. Expect questions on equipment function and correct application rather than deep design.
233 words, about 1 min06Testing, Troubleshooting, and Diagnostics
This domain tests instrument selection, safe measurement, insulation and continuity testing, fault finding, and interpretation of readings. Good diagnostics compare expected values with measured values and isolate one variable at a time.
251 words, about 1 min07Regulations and Standards
This domain tests the difference between law, code, and standards, plus permits, inspections, licensing, adoption dates, local amendments, and special locations. The exam expects you to identify the governing requirement and the authority having jurisdiction.
229 words, about 1 min08Professional Practice and Documentation
This domain tests drawings, schedules, work orders, test records, as-built updates, labelling, handover, and professional communication. The goal is traceable work: another competent person can understand what was installed, tested, and changed.
