Missouri Electrician License — What to Know

Missouri does not have a statewide journeyman license. Kansas City and St. Louis have their own licensing processes.

What the 2020 NEC Covers

The 2020 NEC is the foundation of the Missouri electrician exam. Key articles you must know cold: Article 100 (Definitions), Article 210 (Branch Circuits), Article 220 (Load Calculations), Article 230 (Services), Article 240 (Overcurrent Protection), Article 250 (Grounding & Bonding), Article 310 (Conductors for General Wiring), and Chapter 9 (Tables). Calculation questions based on these articles typically make up 30–40% of the exam.

How to Prepare for the Missouri 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.
