Hi CQD, why does EMT have to be offset when going into a box? Thanks, Jayden Nolasco


Hello Jayden, there is no NEC® requirement for using a box offset in EMT when entering a box. However, there are supporting and securing requirements in Section 358.30(A)&(B). It could be difficult to use a traditional EMT strap to securely fasten EMT within 3ft of a box, especially larger sizes, without first bending an offset to accommodate entry into the box. Additionally, Section 300.10 requires metal raceways, and metal enclosures to be mechanically joined together to provide effective electrical continuity, without an offset the connector may not seat properly in the box opening, making it difficult to comply with this Section. Lastly, Section 110.12 requires installations to be done in a neat and workmanlike manner, using a box offset when installing EMT into a box, is one example of mechanical execution of work.
