It is generally not recommended to run Romex (NM cable) through flex conduit, as Romex is designed for dry, protected locations and not for installation inside conduit. The combination can lead to heat buildup and may violate electrical codes, so it's best to use individual THHN/THWN wires in conduit instead. Always check your local electrical codes before proceeding.
