Flexible Metal Conduit (FMC)

A spirally wound, interlocked metal raceway used where flexibility is needed for connections to equipment that vibrates or requires movement.

Detailed Explanation

FMC (commonly called 'Greenfield') is used for final connections to motors, light fixtures, and equipment in accessible locations. NEC Article 348 covers its installation. Liquidtight flexible metal conduit (LFMC) adds a plastic jacket for wet locations. FMC is limited in length and cannot be used as the sole equipment grounding conductor in most applications over 6 feet.
