22 awg solid core hookup wire 18ga, solid copper wire
The AWG gauge of a stranded wire represents the sum of the cross-sectional areas of the individual strands; the gaps between strands are not counted.
Nomenclature and abbreviations in electrical distribution[ edit ] Alternative ways are commonly used in the electrical industry to specify wire sizes as AWG.
Other types of armored or metallic cable types AC and MC have an aluminum casing that may be used as a ground conductor, for which it is not necessary to calculate an equivalent wire gauge.
A circular mil is the area of a wire one mil in diameter.
Some cables of this type may be flat to save copper. The color is a North American industry standard for cables made sinceand aids identification. The ground wire is typically the same gauge as the others, despite not being intended to carry large amounts of current for more than a few seconds in the event of a short circuit.
The number of strands and the AWG of a strand are separated by a slash. X" wire, where x is the positive integer AWG number. Stranded wires are specified with three numbers, the overall AWG size, the number of strands, and the AWG size of a strand. This sheath for 14 AWG cable is usually white when used for NM-B wiring intended for electrical distribution in a dry location, although older wire may be black.
Wire sized 1 AWG is referred to as "one gauge" or "No.

The higher voltage, used only in large non- residential buildings, allows more than twice as much electrical power in watts to be drawn through the same gauge of wire. Consecutive AWG wire sizes larger than No.
The insulated conductors are black, white, and red, usually supplying both and volts for clothes dryers. An older abbreviation for one thousand circular mils is MCM. Two conductor cable is available with black and red conductors only for this purpose; the outer sheath is likewise red.
It is always used for countertop appliance outlets in kitchens, and often for outlets in bathrooms for high-wattage hair dryers and other rooms.
The most common type of distribution cable, NM-B, is generally implied:
