NCCER Wireways, Raceways & Fittings Practice Test 2026 – Comprehensive Exam Prep

The term "environmental factors" in the context of raceways pertains to weather conditions and potential hazards that may affect the installation and performance of the raceway system. Choosing the correct materials and designing raceway layouts involves understanding these environmental factors to ensure that the system is durable, safe, and effective in various conditions. For instance, raceways installed outdoors may need to withstand moisture, extreme temperatures, or UV exposure, while those in industrial settings might face chemical exposure or the risk of physical damage. This understanding allows for informed decision-making regarding material choice, protective coatings, and installation techniques to effectively mitigate risks associated with a given environment.
