The CIRCUMCENTER. The circumcenter is the center of the circle such that all three vertices of the circle are the same distance away from the circumcenter. Thus, the circumcenter is the point that forms the origin of a circle in which all three vertices of the triangle lie on the circle.
What you're calling outdoor Romex is actually called type UF (underground feeder) cable, it resembles Romex, but it's not. UF cable is THHN conductors plus a ground encased completely in PVC. Romex is a brand name for non-metallic paper bonded cable (NM-B, as printed on the jacket) with a PVC jacket.hat you're calling outdoor Romex is actually called type UF (underground feeder) cable, it resembles Romex, but it's not.

However, this wire count does not include an uninsulated wire that is used as a ground wire, which may or may not be mentioned but is almost always present in modern cabling.. For instance, if the cable lists 12-2 WG, it means there are two insulated 12-gauge wires (a black and a white wire), plus a ground wire.t is incorrect to use Romex to refer to NM cable generically, as the Romex name is a trademarked brand of the Southwire Company. In modern products, the color of the NM cable sheath (or jacket) indicates either the gauge of the current carrying conductors within it, or special properties of the sheathing itself.
