What is the difference between flexible conduit and MC cable?

Flexible metal conduit (FMC) is commonly called “Greenfield.” The main difference between MC cable and FMC is that FMC doesn’t have the insulated wires pre-installed; you have to pull them through instead. It also allows you to add wires in the future, something you can’t do with MC cable.

Where is flexible conduit allowed?
