- Electrical Control Devices and Disconnecting Means (5 questions) — Controllers, disconnects, and the code rules governing when and how they're required.
- Swimming Pool, Spas and Fountain Equipment (18 questions) — The largest topic on the exam. Covers bonding, wiring, equipment placement, and GFCI requirements specific to water features.
How This Practice Exam Helps
Passing requires more than reading — you need to recognize how questions are worded under timed conditions. The full practice exam puts you in those conditions:
- Timed mode matches the real 240-minute limit so pacing isn't a surprise on exam day
- Score tracking shows your result immediately after each attempt
- Topic-by-topic breakdown identifies exactly where you're strong and where you need more work — especially useful for high-weight topics like Swimming Pool, Spas and Fountain Equipment (18 questions) and GFCI/Grounding (15 questions)
- 448+ question pool means no two attempts are identical, so retaking the full exam continues to build new knowledge rather than pattern memorization
