EMC-PSTC'ers,
Where can I find a table(s) or list(s) of the preferred wire sizes
(electrical and otherwise) used in Europe, Japan, and other countries on
the metric system? I'm looking for:
* Names/numbers of standards.
* URL's for wire-manufacturer's websites.
* URL's for distributors' catalogs.
* URL's for web pages on the subject.
* URL's for linecord manufacturer's web pages.
OR
* Anything of the sort that may lead me to this information.
Or can you tell me from your own experience which of the following (or
other?) gages are currently used outside the US? I've gone through
manufacturer's catalogs, searched the Internet, and looked through some
15 bookcases of electronics and metal-working books in my personal
collection without finding a definitive answer as to which metric wire
gages are currently used worldwide.
I am working on the ampacity (current-carrying capacity) appendix to my
new book, Robust Electronic Design Reference, which I am writing for
Kluwer. I also plan to put the wire gage information on dBi's web site,
to make it readily available so that I can get comments and corrections
via the Internet.
In the US we use American Wire Gage (AWG, also called Brown & Sharp
Gage, B&S) and even gages for the most part, which correspond to a
roughly 20% reduction in diameter for each step.
So far I have found tables that specify metric cross-sectional area in:
* Hitachi Electronic Wires and Cables catalog, 1991-- page 278 lists
JIS sizes for 0.035, 0.05, 0.1, 0.14, 0.18. 0.2, 0.3, 0.5, 0.75,
1.25, 2, 3.5, 5.5, 8, 14, 22, 38, 60, and 100 mm^2.
* Oleflex Cable Advanced Cable Technology catalog, 1984/1985-- page 54
lists European Cable Stranding for 0.14, 0.25, 0.34, 0.38, 0.5, 0.75,
1.0, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240,
300, 400, and 500 mm^2.
* IEC 950, 1996-- Table 11 lists sizes of conductors for power supply
cords of 0.75, 1.00, 1.25, 1.5, 2.5, 4, 6, 10, 16, 25, 35, and 50
mm^2.
I have found tables that specify metric diameters for solid wires:
* Querschnitt und Gewicht von Runddrahten aus Kupfer, date unknown--
page unknown lists Durchmesser (diameters) of 0.04, 0.05, 0.56, 0.06,
0.063, 0.07, 0.08, 0.09, 0.1, 0.112, 0.118, 0.125, 0.132, 0.14, 0.15,
0.16, 0.17, 0.18, 0.19, 0.2, 0.224, 0.236, 0.25, 0.265, 0.28, 0.3,
0.315, 0.335, 0.355, 0.38, 0.4, 0.425, 0.45, 0.475, 0.5, 0.53, 0.56,
0.6, 0.63, 0.65, 0.71, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.06, 1.12,
1.18, 1.25, 1.32, 1.4, 1.5, 1.6, 1.8, 2, 2.5, 2.65, and 3 mm.
* Metric wire gage-- gages 0.5 to 100 corresponding to diameters of
0.050mm to 10.0mm.
* German Wire Gage (GWG)-- gages 1 through 25 corresponding to
diameters of 5.5mm to 0.438mm.
I've also found tables based on diameters in inches:
* British Standard Wire Gage (SWG), also called New British Standard
(NBS), English Legal Standard, and Imperial Wire Gage.
* Birmingham Wire Gage (BWG), also called Stub's Iron Wire Gage.
* London Gage, also called the Old English Wire Gage.
* Twist Drill Gage.
* Stubs Steel Wire Gage.
* Steel Wire Gage (Stl.W.G.), also called Washburn & Moen (W&M),
Roebling steel wire gage, or American Steel & Wire Co.'s gage.
* Steel music wire gage.
* Music wire gage.
But some of my sources go back to the 1940's, so I don't know how far I
can trust them...
Thanks!
