Electrician's Licensing Practice Exam 2026 - Free Electrician License Practice Questions and Study Guide

The correct choice relates specifically to the provisions and regulations regarding the installation and use of raceways in electrical systems. NEC Article 386 pertains to metallic wireways, which are designed for the protection and management of electrical conductors and related wiring. Article 388, on the other hand, covers non-metallic raceways, focusing on materials and methods used to support and protect wiring within a structure. Both articles provide crucial guidelines that help electricians ensure safe and compliant installations of both types of raceways, which is essential for maintaining the integrity of electrical systems.

The other articles mentioned do not address raceways in the same context. For example, Articles 400 and 402 deal with flexible cords, cables, and conductors, while Articles 210 and 250 focus on circuits and grounding systems. Articles 300 and 310 cover general wiring methods and conductors, respectively, but do not specifically target raceway systems. Understanding the application of each article helps electricians navigate installation practices that adhere to the National Electrical Code (NEC).
