Codes & Standards (NCEES-cited references)
Quick-reference index of the codes and standards the NCEES PE Power exam scores against (Oct 2025 edition). Lessons here are cross-listed from their canonical NCEES topic (2.E Grounding / 3.A Wiring methods / 3.D Shock and burns).
Chapters
A. NEC — NFPA 70-2020 (National Electrical Code)
NFPA 70-2020 — the customer-side premises wiring code. NEC Article 250 grounding + bonding, NEC Article 430 motor branch circuits + feeders.
B. NFPA 70E-2021 (Electrical Safety in the Workplace)
NFPA 70E-2021 — OSHA-referenced safety standard for energized work. 110.4 when allowed, 130.2 EEWP, 130.4 approach boundaries, 130.5 Arc Flash Boundary + IEEE 1584-2018 incident-energy analysis, 130.7(C)(15) PPE categories.
C. NESC — ANSI C2-2017 (National Electrical Safety Code)
ANSI C2-2017 — utility-side supply + communication lines. Rule 232 vertical clearances, Rule 232C voltage + altitude adders, Rule 234 building/pool clearances, Rule 235/236 climbing space, Part 4 MAD for live-line work. NCEES Oct 2025 exam uses the 2017 edition; our lesson cites the more-current C2-2023 (clearance values largely unchanged between editions).
