What the 2022 California Electrical Code (based on 2020 NEC) Covers
The 2022 California Electrical Code (based on 2020 NEC) is the foundation of the California electrician exam.

How to Prepare for the California Exam
Most successful candidates spend 60–100 hours studying over 4–8 weeks. Tab your NEC by article number so you can find answers in seconds, not minutes. Focus on voltage drop calculations (NEC 210.19 informational note), conductor ampacity tables (Table 310.12), and demand factor applications (Article 220). The Electrician Prep app includes 1,000+ NEC practice questions and a built-in voltage drop calculator — the same tools you'll use on the job.
