THHN is a type of insulation temperature rated for at least 90 C. BX is a flexible outer jacketed cable with several insulated conductors inside it. My preference would actually be 10 gauge MC which is a metal clad flexible multiconductor cable which already has a full size ground wire in it. BX typically relied on the steel outer jacket with an internal flimsy aluminum drain wire to act as the ground. Thin wall conduit is also permited in commercial buildings and would be an excellent alternative as well.
Dedicated outlets, 10ga, and what else?
I asked my electrician for 10ga romex for my dedicated outlets, and am using Albert Porter's cryo'd hubbell outlet, but the electrician said since I'm living in a commercial building, I can't have romex. He suggested THHN (but also has I think BX available).
What would you suggest I go with... the THHN or BX? (I have no idea what either is!)
