Georgia Electrical Contractor Class I Exam —
10 MOST-TESTED EXAM COVERAGE AREAS
1. Georgia Laws, Licensing & Contractor Responsibilities — licensing rules, workers’
compensation, unemployment insurance, taxes, business requirements, permits, inspections,
and responsibilities of the electrical contractor.
2. OSHA, NEC, NFPA & Electrical Regulations — safe work practices, applicable OSHA construction
requirements, NEC requirements, NFPA standards, UL/NRTL listings, permits, and inspections.
3. Electrical Theory & Basic Calculations — voltage, current, resistance, power, Ohm’s Law, AC/DC
circuits, series and parallel circuits, conductor calculations, and basic electrical formulas.
4. Conductors, Cables & Wiring Methods — conductor types, ampacity, insulation, raceways,
cable systems, conduit fill, conductor identification, splicing, terminations, and protection.
5. Grounding & Bonding — grounding electrode systems, equipment grounding conductors,
bonding, grounding electrode conductors, service bonding, and fault-current paths.
6. Services, Feeders & Branch Circuits — service equipment, disconnects, overcurrent protection,
feeder sizing, branch circuits, panelboards, load calculations, and circuit protection.
7. Electrical Equipment & Installations — transformers, switchboards, panelboards, disconnects,
receptacles, switches, lighting equipment, appliances, and other electrical equipment.
8. Motors, Generators & Motor Controls — motor circuits, overload protection, disconnecting
means, controllers, starters, generators, and related wiring requirements.
9. Special Locations & Special Systems — wet locations, hazardous locations, garages, pools,
temporary installations, emergency systems, fire alarm-related requirements, and other special
installations.
10. Electrical Safety, Testing & Troubleshooting — lockout/tagout concepts, PPE, testing,
inspection, fault finding, voltage checks, continuity, equipment protection, and safe
troubleshooting.
1.
A Georgia electrical contractor begins work on a new project before obtaining the required electrical
permit. What is the best action?
, Page 2 of 148
A. Continue because the contractor holds a license
B. Obtain the required permit before starting regulated work
C. Ask the customer to approve the work verbally
D. Start the work and obtain inspection after completion
Answer: B
Rationale: Required permits should be obtained before regulated electrical work begins. Licensing does
not replace permitting requirements.
2.
A circuit has 120 volts and 10 amperes of current. What is the approximate resistance of the circuit?
A. 6 ohms
B. 10 ohms
C. 12 ohms
D. 120 ohms
Answer: C
Rationale: Using Ohm’s Law, R = V ÷ I. Therefore, 120 ÷ 10 = 12 ohms.

3.
During an inspection, an electrical inspector identifies a violation of the applicable electrical code. What
should the contractor do first?
A. Ignore the inspector
B. Correct the violation according to applicable requirements
C. Remove the inspector from the project
D. Cover the installation before another inspection
Answer: B
Rationale: Electrical installations must comply with applicable code requirements and inspection
findings should be corrected.
4.
A 120-volt load draws 15 amperes during normal operation. Approximately how much power does the
load use?
A. 125 watts
B. 180 watts
, Page 4 of 148
C. 1,800 watts
D. 18,000 watts
Answer: C
Rationale: Power equals voltage multiplied by current. 120 × 15 = 1,800 watts.
5.
A contractor needs to verify whether electrical equipment has been evaluated by an accepted testing
organization. Which marking is most useful?
A. UL or other NRTL listing
B. Contractor business card
C. Customer purchase receipt
D. Manufacturer advertising brochure
Answer: A
Rationale: UL and other recognized testing laboratories provide equipment evaluation and certification
markings.
