Wireway
A sheet-metal or nonmetallic trough with a hinged or removable cover, used for housing and protecting conductors, typically at junction points between multiple conduit runs.
Detailed Explanation
NEC Articles 376 (metal wireways) and 378 (nonmetallic wireways) cover installation requirements. Wireways are limited to 20% fill (cross-sectional area). They must be supported at intervals not exceeding 5 feet and within 3 feet of each outlet box or cabinet. Wireways are commonly used in industrial settings and above panelboards where many circuits originate, providing easy access to conductors through the hinged cover.
