Stranded wires are calculated by calculating the equivalent cross sectional copper area. A circular mil is the area of a wire one mil in diameter. Please first verify your email before subscribing to alerts.
ASTM B258 – 18
The most common type of distribution cable, NM-B, is generally implied:. Increasing gauge numbers denote decreasing wire diameters, which is b528 to many other non-metric gauging systems such as SWG.

Referenced Documents purchase separately The documents listed qstm are referenced within the subject standard but are not provided as part of the standard.
The ratio of these diameters is 1: Turns of wire is an upper limit for wire with no insulation.

Subscription pricing is determined by: In this case, it describes a wire which b2588 equal in cross-sectional area to the total of all the cross-sectional areas of the individual strands; the gaps between strands are not counted. Combining values of the two systems may result in nonconformance with the specification.
Combining values of the two systems may result in nonconformance with the specification. Mini Christmas lights were mostly 24 throughwhen that gauge was arbitrarily de-rated from 3 to 2. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.
An older abbreviation for one thousand circular mils is MCM. This standard is not b28 in any packages. Click here to download full list of books. Enter your account email address to request a password reset: Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically.

In particular, the maximum permissible overcurrent protection devices may set a lower limit. This standard is not included in any packages. High-purity oxygen-free copper can achieve up to It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Each system shall be used independently of the other. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This specification prescribes the standard nominal diameters and cross-sectional areas of American Wire Gage AWG sizes of solid round wires, used as electrical conductors, and xstm equations and rules for the asrm of standard nominal mass and lengths, resistances, and breaking or rated strengths of such wires.
