Multiple Choice

Secondary or service wire that contains two phase conductors wrapped around a single neutral conductor is referred to as:

This arrangement uses three conductors in one assembly: two insulated phase conductors wrapped around a single neutral conductor. That three-conductor configuration is what gives the term triplex. It’s the standard overhead service cable for delivering a single-phase service, with the two hot wires surrounding the neutral, often a bare conductor. Duplex would imply only two conductors, which doesn’t match the described three-conductor setup. Quadruplex would imply four conductors, which isn’t the case here. Doublet isn’t the common term used for this overhead service cable.
