Whether an electrical wire needs to be in a conduit depends on various factors, including local building codes, the type of wire being used, the location of the wiring, and the conditions the wiring will be exposed to.
In general, electrical wiring in many areas must be enclosed in a conduit if it is installed in areas where it might be damaged, such as in underground or wet locations, or if it is exposed to physical damage. The conduit provides a protective barrier for the wire and helps to prevent electrical shocks or short circuits.
Additionally, electrical wiring in certain high-risk areas, such as hazardous or damp locations, may require special types of conduits that provide additional protection. For example, conduit made of metal provides better protection against electrical hazards than plastic conduit.
It is important to follow local building codes and safety regulations when installing electrical wiring, and to consult a licensed electrician if you are unsure about the requirements for your specific installation.
