 Electrical Wiring Faults — Fire Hazards
A sizable fraction of ignitions of structures are due to electrical faults associated with wiring or with wiring devices.
Electrical failure was considered to be a short circuit or a low-resistance condition developed across the line;  experiments were not conducted to actually elicit ignitions.
In the US, the safety of wiring and wiring devices is generally assessed according to UL standards, but there exists almost no published material from UL that would document their studies of ignition mechanisms, nor to provide a basis for judging whether their test procedures have a traceable connection to field failure modes.

 Electrical wiring (United States) - Wikipedia, the free encyclopedia
Switch-leg is a wiring configuration in which the full-potential circuit is available at the fixture location, while one half of the circuit (hot in new installations, but often neutral in older knob-and-tube systems) is routed from the fixture location, through a switch, and back and into the fixture itself.
The phase wire for a switch "leg" is the white wire of a two insulated wire cable, the fl wire is connected to the light.
The National Electrical Code specifies that the fl conductor represent the hot conductor, with significant voltage to earth ground; the white conductor represent the identified or neutral conductor, near ground potential; and the bare/green conductor, the safety grounding conductor not normally used to carry circuit current.

 Electrical wiring - Wikipedia, the free encyclopedia
Electrical wiring in general refers to insulated conductors used to carry electricity, and associated devices.
Wiring systems in a single family home or duplex, for example, are simple, with relatively low power requirements, infrequent changes to the building structure and layout, usually with dry, moderate temperature, and noncorrosive environmental conditions.
Wiring in exposed areas, for example factory floors, may be run in cable trays or rectrangular raceways having lids.

Electrical wires are color coded to prevent wiring errors.
Attach the white wire to the chrome terminal, the fl wire to the brass terminal on the receptacle and to the box, if the box is metal.
New wiring can also be tied into a junction box, unless the wiring in the junction box is already at maximum capacity.

 Electrical Wiring
Don’t confuse the danger of working with electrical cables, wires and boxes that have yet to be connected to the circuit panel board, with the hidden dangers of energized electrical wiring that can arc and overheat causing a fire.
All of the wiring in a particular circuit must be matched to the size of the circuit breaker controlling the circuit.
Installing wire nuts and twisting conductors the right way may seem intuitive, but if done improperly these critical connections can be the source of electrical fires months or years from now.

 RV Wiring   (Site not responding. Last check: 2007-10-11)
The receptacle is wired with three wires from the breaker panel and requires a single, dedicated 30 amp breaker.
Please remember that this applies to ALL wire associated with RV wiring whether it is the wiring from the breaker(s) to the socket or receptacle, the umbilical from the RV to the socket or the wiring inside the RV.
After completing all the wiring and closing up the boxes, it is a good idea to test the outlet for proper wiring with a voltmeter or appropriate circuit tester.

And while most OE Detroit wiring is rated at 300 volts and covered with PVC insulation, Painless uses superior 600-volt, TXL-insulated wire capable of withstanding 257 degrees F ambient temperature (OE insulation is rated at 176 degrees).
A popular misconception is that electrical current flows through wire; it actually flows along the outer surface of the wire, not inside it.
Where wires pass through the firewall (or any other metal barrier), be sure to avoid (shorts caused by) abrasion with rubber grommets.

 Commercial Electrical Wiring to the 1999 NEC - CBC-CEW
Few, however, are aimed directly at commercial electrical wiring - the type of electrical construction that uses the most electricians, the greatest amount of materials, and for which the greatest amount of working drawings and specifications are prepared.
Electrical wiring systems for commercial buildings can vary considerably - from a few lighting fixtures and a couple of convenience outlets for a small, one-room vegetable stand (Figure 1-1) to extremely complex installations used in high-rise office or apartment buildings (Figure 1-2).
Therefore, when the electrical technician is called on to design or install a commercial electrical installation, there should really be no "strange" jobs once he or she has worked on a few commercial installations.
