Generally speaking, yes, outdoor wiring needs to be in conduit to protect it from physical damage. Type UF cable needs conduit when exposed, no need for conduit on the buried sections.
When should you run conduit?
Conduit typically is used only where circuit wires are exposed (or surface-mounted or buried) and therefore need protection from damage or moisture. Conduit offers protection to electrical wires that run in exposed locations.
Where is conduit required?
Available in either rigid or flexible forms, a conduit protects the wires and is used in exposed locations (such as along the exterior surface of a wall) as well as in unfinished areas (like basements, crawlspaces, and attics), and in surface-mounted installations outdoors.
Should I use PVC or metal conduit outside?
PVC conduit provides protection for electrical work that is buried underground. Out of the many conduit forms available, PVC conduit is considered best for outdoor applications.
What type of conduit should be used outdoors?
Nonmetallic conduit is typically made from PVC and is a good choice for outdoor residential applications. Blue electrical nonmetal tubing (ENT) is for indoor use only.
Does outdoor Romex need conduit?
Does Exposed Romex Need to Be in Conduit? When using any non-metallic wiring in an outdoor application, you should run the wiring through a conduit. Using a conduit is ideal because it is always better to add more protection to exterior wiring than not enough protection.

Is it OK to use Romex outside?
Romex is a type of electrical wire used in various applications. Romex wires cannot be used outdoors because, if it gets wet with water, gas, oil or another solvent, these liquids could penetrate the jacket and ruin the connection by getting in contact with the bare copper ground wire.

Where is the best place to use an electrical conduit?
Electrical conduit is metal or plastic pipe through which electrical wires are run. Either rigid or flexible, conduit protects the wires and is used in exposed locations, such as along the exterior surface of a wall.
