• Special Conditions – approximately 12 to 14 questions
• Communication Systems – approximately 10 to 12 questions

Wiring Methods and Materials is one of the largest code areas, followed by Wiring and Protection. Candidates should be able to apply Chicago-specific electrical requirements rather than relying only on general National Electrical Code knowledge.

Open Book Test

The Chicago Supervising Electrician Examination is an open book test, but the open-book policy is limited.

The current examination rules state that the 2018 Chicago Electrical Code is the only book a candidate is permitted to bring into the examination. The copy must be clean and printed. Tabs may be used to mark sections of the code, but notes, highlighting, and other changes to the published text are prohibited.

Continental Testing Services also provides a reference document containing changes made after publication of the 2018 Chicago Electrical Code. A clean copy of that document is provided to candidates at the examination, and candidates may also use the study version during preparation.

The other books in this package are study references. They are intended to help candidates prepare for electrical principles, calculations, OSHA safety, and municipal requirements, but they are not additional books that candidates may bring into the testing room under the current CTS rules.

Candidates should therefore use the Chicago Electrical Code extensively during preparation and build speed with its organization. Familiarity with articles, sections, tables, definitions, wiring requirements, special occupancies, and equipment provisions can help candidates manage a 150-question examination within the four-hour time limit.

State Requirements

The Supervising Electrician credential is a City of Chicago license. It is tied to electrical work performed under Chicago's licensing and electrical-code requirements rather than a general statewide Illinois electrician license.

Current examination requirements identify only two testing categories: Supervising Electrician and Supervising Low Voltage Electrician. This product is designed for the full Supervising Electrician examination, not the separate low-voltage examination.

Applicants for the Supervising Electrician examination must be at least 21 years old and must demonstrate a minimum of two years of cumulative qualifying electrical work experience.

For experience obtained through a Chicago electrical contractor, the verification documentation must establish the applicant's dates of employment, describe duties and responsibilities, and be supported by the appropriate licensed supervising electrician and electrical contractor information.

Applicants whose qualifying experience was obtained in a jurisdiction that does not license or register electrical contractors or does not require electrical wiring permits may be required to provide verification from that jurisdiction together with a detailed work history.

Passing the examination is one part of obtaining the license. Candidates must also complete all application, documentation, and licensing requirements established by the City of Chicago.

Test Information and Study Materials

A strong preparation plan should reflect the fact that 125 of the 150 questions are devoted to the Chicago Electrical Code. Candidates should spend substantial time navigating the 2018 code and understanding how Chicago requirements differ from general NEC provisions.

Wiring Methods and Materials represents approximately 22 to 25 questions. Review raceways, conductors, cable applications, boxes, fittings, support methods, protection from physical damage, installation requirements, and material restrictions.

Wiring and Protection contains approximately 18 to 22 questions. Study branch circuits, feeders, services, overcurrent protection, grounding and bonding, load calculations, conductor sizing, and related requirements.

Equipment for General Use contains approximately 12 to 14 questions. Review motors, transformers, appliances, luminaires, switches, receptacles, equipment connections, and other commonly installed electrical equipment.

Special Occupancies and Special Conditions each account for approximately 12 to 14 questions. Candidates should be familiar with code requirements for specialized buildings, hazardous locations, emergency systems, standby systems, and other installations governed by special provisions.

Special Equipment contains approximately 12 questions. Study equipment-specific requirements and know how specialized installations differ from standard wiring applications.

Communication Systems contributes approximately 10 to 12 questions. Review applicable requirements for communication wiring and related low-voltage systems within the Chicago Electrical Code.

The Electrical Principles and Practices section requires technical knowledge beyond direct code lookup. Candidates should review Ohm's law, electrical units, alternating current, power relationships, three-phase calculations, conductor resistance, voltage drop, transformers, delta and wye systems, power factor, and blueprint interpretation.

The official sample questions demonstrate the mathematical level candidates may encounter. Topics include three-phase generator current, voltage drop in conductors, electrical units, transformer relationships, conductor characteristics, and code application.

OSHA regulations and workplace safety account for approximately 6 to 8 questions within Electrical Principles and Practices. Review construction electrical safety, fall protection, personal protective equipment, ladders, scaffolds, tools, hazardous conditions, and general employer safety responsibilities.

The selected Chicago municipal-code provisions should also receive focused study. Approximately 8 to 10 questions are assigned to Titles 2, 4, and Chapter 13 material. Candidates should become familiar with the organization of this supplement and the responsibilities it establishes.

Because candidates may bring only the clean 2018 Chicago Electrical Code into the examination, study sessions should gradually transition from using all references to working primarily with the code book. Use the American Electrician's Handbook and OSHA material to learn concepts, then practice applying that knowledge without depending on those books.

Timed practice is useful because 150 questions in four hours provides an average of approximately 1.6 minutes per question. Candidates should identify straightforward code questions quickly, avoid spending excessive time on a single calculation, and maintain a steady testing pace.

Practice code navigation using the same tabbing approach permitted at the examination. Organizing tabs by major code divisions can help candidates move efficiently among wiring methods, protection, equipment, special occupancies, and communication systems without violating the no-highlighting and no-notes rules.
