Hold the wires together so the ends match up and twist them together in a clockwise direction using lineman pliers. Make 1 or 2 turns to form a solid union being careful not to dig into the copper with the plier jaws.
A rigid, flat metal tape used to run electrical cable through a finished wall or ceiling. The rigid nature of the tape makes it possible to push it past most obstructions in the wall cavity by turning the reel to either side. See Run New Wiring for more about fishing cable.
Fit a nail guard into each notch, covering the new wires. Drive the plates down tightly making sure they are flush and not protruding from the stud surface.
In this example a new wall receptacle can be installed using an existing receptacle in an adjacent room. This can often be the easiest and most likely solution to access a source for a new receptacle or a switch to a new light fixture. Set the new outlet box in the same wall space as the existing one to simplify running the cable.
Carefully nail the molding just above and/or below the metal shield at each stud. Caulk the trim seams, fill the nail holes, and touch up the wall and molding paint.
Electric cable with spiral metal sheathing. Early armored cable, BX cable, carried two electric wires with no ground. The metal sheath served as the ground. Later versions carried an aluminum ground wire, wound in the spiral. Newer armored cable includes an insulated ground wire.
Two or more wires housed in a protective sheathing is referred to as electrical cable. Armored, UF and NM are all names for household electrical cable. Each cable type is available for different wire gauge. Standard household electrical cable ranges from 14 awg (american wire gauge) to 6 awg, with 14 having the smallest conductors and 6 having the largest. In household electrical systems 14 gauge wire is used for 15 amp circuits, 12 gauge for 20 amp circuits, 10 awg for 30 amps, 8 awg for 40amps and 6 awg for 50 and 60 amp circuits.
A current-carrying wire in an electrical circuit. There may be one or two hot wires in a household electrical circuit. These wires are always insulated and may be colored black or red, or in the case of some ceiling fans, the hot wire may also be colored blue.
