Electrical Exam Term
Electrical Metallic Tubing (EMT)
A thin-walled, unthreaded metal raceway commonly used in commercial and residential construction for protecting electrical conductors.
Detailed Explanation
EMT is lightweight, easy to bend, and economical. It uses set-screw or compression fittings rather than threads. NEC Article 358 covers EMT installation requirements, including support intervals (every 10 feet and within 3 feet of boxes), maximum bending angles (360 degrees total between pull points), and prohibition in areas subject to severe physical damage or corrosive environments.
