In North American practice, for residential and light commercial buildings fed with a single-phase split 120/240 service, an overhead cable from a transformer on a power pole is run to the service entrance point. The cable is a three conductor twisted "triplex" cable with a bare neutral and two insulated conductors, with no overall cable jacket ...
The cable system in Mahanoy City became a sister company to Service Electric Cable TV & Communications, taking the name Service Electric Cablevision and serving Birdsboro, Hazleton, and Sunbury. John E. Walson, eldest son of John Walson, ran Service Electric Cable TV, Inc. for 38 years until his death in August 2012.
[1] Hot is any line or neutral conductor (wire or otherwise) connected with an electrical system that has electric potential relative to electrical ground or line to neutral. Ground is a safety conductor with a low impedance path to earth. It is often called the "ground wire," or safety ground. It is either bare or has green insulation. [1]
A three phase electric circuit terminated with a pothead Crossarms with two three phase electric circuits terminated with potheads. A pothead is a type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers.

The numbers of wire were in common use earlier than 1735 when the measurements were officially defined. [1] It is believed that they originally were based on the series of drawn wires, No. 1 being the original rod, and succeeding numbers corresponding with each draw, so that No. 10, for example, would have passed ten times through the draw plate .
In recent years, DIRT has demonstrated a trend of greater excavation damage incidents over time. [8] This report does not contain every single incident, as stakeholders voluntarily submit underground damages and near-miss reports, but it is the most complete repository of utility damages anywhere in the world.
The first 8000 series electric conductor alloy, still widely used in some applications, was developed and patented in 1972 by Aluminum Company of America . [8] This alloy, along with AA-8030 (patented by Olin in 1973) and AA-8176 (patented by Southwire in 1975 and 1980), performs mechanically like copper.
An electrical cable is an assembly of one or more wires running side by side or bundled, which is used as an electrical conductor to carry electric current. Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals , power , or both from one device to the other.
