Great question! No — 6/3 NM‑B (Romex®) cannot be used underground, even if it is buried inside conduit. NM‑B is rated indoor/dry‑location only and is not approved for wet or damp locations, including underground conduit where moisture is always present. Please let us know if you need help in any other way by contacting us at consumersupport@southwire.com. Provide your feedback on BizChat
