Splices and Conductor Fill in Enclosures and Wireways

摘要

The conductor fill requirements for a conduit or an outlet box are calculated in the field on a regular basis. However, field people seldom determine the conductor fill requirements for a surface metal or non-metallic raceway (Article 352), a metal or nonmetallic wireway (Article 362), or the wire space for a cabinet or cutout box (Article 373. The calculation is neither difficult nor mysterious if a few simple rules within the National Electrical Code (NEC) are followed.
