Article 230.6 is pretty clear on what conductors are considered outside of the building. For 600V or less underground service conductors, according to 230.32, I could either install service entrance conductors per 230.6 OR per 230.43 which is NOT concrete encased. For over 600V (article 230.202) i am allowed to install per 300.37 which is NOT concrete encased. Could someone clarify 2" concrete encasement requirement, the way I see it is not required.
Is there a different requirement for a service conductor vs. service entrance conductor?
thank you
