Under NEC, which article would you refer to for uses not permitted in certain locations?

The correct reference for uses not permitted in certain locations under the National Electrical Code (NEC) is found in Article 100, which outlines definitions and includes the specifics about different locations and the appropriate uses of equipment and installations. The name of this article indicates that it provides fundamental rules that govern where certain types of equipment and electrical installations can be used.

Article 500 pertains to hazardous locations, specifying what equipment and wiring methods are allowed in areas where there is a potential for explosive atmospheres. It deals with hazardous classifications and standards, but it is specific to locations that have inherent risks due to flammable materials.

Article 12 is not a recognized article within the NEC. Instead, it typically refers to standards and guidelines for specific installations.

Article 300 contains general requirements for wiring methods and materials which apply to all installations, without specifically addressing what is permitted or not permitted in particular locations.

The focus on uses not permitted in certain locations highlights the necessity of understanding which installations or equipment are safe according to specific environmental conditions, making the content within Article 100 essential for determining the limitations of electrical installations based on location.
