Each overhead wire is connected to a bushing terminal from which the current passes through a rod down the center of the bushing to the interior of the housing, where it is connected to a wire from the conduit. Thus the device allows the overhead conductors to pass into the conduit while serving as a seal to keep out water.
The temperature rating of a wire or cable is generally the maximum safe ambient temperature that the wire can carry full-load power without the cable insulation melting, oxidizing, or self-igniting. A full-load wire does heat up slightly due to the metallic resistance of the wire, but this wire heating is factored into the cable's temperature ...
The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking with ridged, grooves or white stripes on the surface of lamp cord.

It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over ...
The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
The RV Industry Association argued in a Dec. 4 statement that because of a lack of certified zero-emission motorhome chassis, which is the vehicles' supporting frame, the rule could impact the ...
The undergrounding must be in National Parks or designated Areas of Outstanding Natural Beauty (AONB) to qualify. In 2021 work started on a project to bury 9 kilometres (5.6 mi) of 400kV overhead power lines running from near Winterbourne Abbas to Friar Waddon ( 50°40′08″N 2°30′50″W / 50.669°N 2.514°W / 50.669; -2.514 ...
