    Does plastic conduit provide insulation ... or is it there for mechanical protection?

    Does the sheath of a cable provide insulation ... or is it there for mechanical protection?


     


    Cable sheath and plastic conduit> Electrical insulation and/or mechanical protection? That is the question.


    It is primarily for mechanical protection BUT also by virtue of its construction and material offers electrical insulation as well.
