How the GAEC Exam Is Structured
The Georgia Electrical Contractor License Exam (Class II Unrestricted) - administered by PSI on behalf of the Georgia State Board of Electrical Contractors - is built from 140 scored multiple-choice questions plus 22 unscored beta questions that PSI uses to evaluate future exam content. Candidates won't know which questions are scored and which are experimental, so every question deserves full attention.
The test is split into two 4-hour parts, and you'll need a final scaled score of 70 to pass. Because the exam is open book, your ability to navigate approved references quickly under time pressure matters almost as much as your raw electrical knowledge. Permanent tabs, highlighting, and underlining in your code books are allowed, but handwritten notes are prohibited, and only a silent, nonprogrammable calculator is permitted at your station.

Domains 1-4: Laws, Regulations, and Administration
The first four domains are grouped conceptually because they test your understanding of the regulatory and business environment surrounding Georgia electrical contracting, rather than pure wiring theory. Combined, they represent 21.43% of the scored exam - smaller individually, but not safe to skip.
Domain 1: Comply with Laws (7.14%)
Candidates must understand the statutory framework governing electrical contracting in Georgia, including how the Georgia State Board of Electrical Contractors operates within the Georgia Construction Industry Licensing Board.
- Licensing law scope and applicability
- Board authority and enforcement provisions
- Consequences of unlicensed contracting
Domain 2: Comply with Regulations (6.43%)
This domain focuses on the administrative rules that implement the licensing law, distinct from the statute itself.
- Board rules on license classifications
- Continuing education and renewal rule requirements
- Rules affecting supervision and unrestricted Class II scope
Domain 3: Comply with Administrative Requirements (4.29%)
Smaller in weight but heavy on procedural detail - how paperwork, permits, and documentation move through the system.
- Permit application processes
- Recordkeeping obligations
- Inspection scheduling and documentation
Domain 4: Plan and Organize Work (3.57%)
The smallest domain by weight, covering project-level planning judgment rather than code specifics.
- Sequencing work to meet code and safety requirements
- Coordinating with other trades on a jobsite
- Resource and material planning basics
Key Takeaway
Domains 1-4 total roughly a fifth of the exam. Don't over-invest study time here at the expense of the high-weight technical domains, but don't skip them either - every point counts toward the 70-point scaled score.
Domains 5-10: The Technical Core
The remaining six domains make up nearly 79% of the scored exam and test the hands-on knowledge you'd apply on a real Class II job - from basic circuit theory through specialized equipment and hazardous locations.
Domain 5: Maintain Basic Electrical Circuits (10%)
This is your foundation domain - Ohm's Law, series and parallel circuit analysis, and troubleshooting fundamentals that later domains build on.
- Voltage, current, resistance, and power calculations
- Series, parallel, and combination circuit analysis
- Basic fault-finding and continuity testing
Domain 6: Install and Maintain Electrical Controls and Devices (10.71%)
Covers the switching, protective, and control devices that govern how circuits are operated and protected.
- Overcurrent protection devices and their ratings
- Control relays, contactors, and switching devices
- Device installation and maintenance practices
Domain 7: Install and Maintain D-C and A-C Rotating Equipment (11.43%)
Motors and generators - how they're wired, protected, and maintained.
- Motor starting, running, and overload protection
- AC vs. DC rotating equipment characteristics
- Generator installation and interconnection basics
Domain 8: Install, Size, and Maintain Transformers (15%)
One of the three heaviest domains. Candidates must be comfortable with transformer theory and sizing calculations under open-book time pressure.
- Transformer sizing formulas and kVA calculations
- Single-phase and three-phase transformer connections
- Grounding and overcurrent protection for transformers
Domain 9: Install and Maintain Interior Electrical Systems (16.43%)
The single largest domain on the exam - this is where the bulk of your reference-navigation speed and code fluency will be tested.
- Branch circuit and feeder calculations
- Wiring methods and conductor sizing/ampacity
- Panelboard and service equipment installation
Domain 10: Special Equipment, Conditions, and Locations (15%)
Tied with transformers for second-highest weight - expect questions on hazardous locations, health care facilities, and other special-occupancy requirements.
- Hazardous (classified) location requirements
- Special occupancies and equipment
- Environmental and condition-specific installation rules
Sequencing Your Study by Domain Weight
Rather than studying domains in numerical order, allocate time proportional to their weight. A practical approach: front-load Domains 9, 8, and 10 since they carry the most points, then work backward through the mid-weight technical domains, and finish with the lighter legal/administrative domains as a review pass.
Interior Systems & Transformers
- Branch circuit and feeder calculations (Domain 9)
- Transformer sizing and connections (Domain 8)
Special Equipment & Rotating Equipment
- Hazardous locations and special occupancies (Domain 10)
- Motor and generator protection basics (Domain 7)
Circuits & Controls
- Circuit analysis fundamentals (Domain 5)
- Controls and protective devices (Domain 6)
Laws, Regulations & Admin
- Licensing law and Board rules (Domains 1-2)
- Administrative procedures and work planning (Domains 3-4)
Full Timed Practice
- Simulate the two 4-hour parts under exam conditions
- Drill reference-navigation speed for open-book questions

Registration, Fees, and Exam-Day Mechanics
Understanding the domains is only half the battle - you also need to navigate the application and testing process correctly. The current licensure-by-examination application fee is $110. Applications require work-experience documentation, affidavits or references, identity and lawful-presence documents, and a background check.
Under the licensing law effective July 1, 2026, the standard experience path requires four years of full-time electrical experience, including at least two years installing, altering, or repairing three-phase systems - directly relevant to how heavily Domains 7 and 8 weight rotating equipment and transformers. Education and U.S. Department of Labor-approved apprenticeship pathways are also available for candidates who qualify through those routes. Full eligibility details are covered in GAEC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Once approved, your exam authorization is valid for one year, and after two failed attempts a Board-approved review course is required before you can retest - plan your domain study accordingly rather than rushing an unprepared first attempt.
Licenses renew by June 30 of even-numbered years, requiring 8 continuing-education hours per cycle reported through CE Broker.

Why These Domains Match Real Georgia Electrical Work
The domain structure isn't arbitrary - it mirrors the day-to-day scope of an unrestricted Class II contractor. Heavy weighting on interior systems (Domain 9), transformers (Domain 8), and special locations (Domain 10) reflects the reality that licensed contractors are expected to handle everything from standard residential/commercial wiring to industrial transformer work and hazardous-location installations, without scope restrictions.
This breadth is also why the credential carries weight with employers who need contractors capable of running diverse jobs.
