Re: [802.3_RTPGE] Update: Implications of Wire size on maximum available load power

Yes, the standard metric wire sizes are not equivalent to American wire gauges.

Sterling-

That is as I understand it
BUT (I believe) that the most commonly used sizes are not precisely equivalent to the commonly used sizes in an AWG environment.

Metric wire sizes are specified by the cross-sectional area in mm^2. American wire sizes are specified by a gauge that can be cross-referenced to a cross-sectional area.

In Europe at least, wire sizes are specified using the metric system.

Yair-
I did not mean the cross sectional area in metric
I meant the wire sizes actually used in the auto industry world-wide.
I suspect those are based on metric sizes, not AWG

Geoff,

 

Did you look at the updated presentation that I have sent yesterday (rev-001). In page 11 and 12 , right after the AWG wire size line, there is copper area in mm^2, is that what you meant is missing or the other parameter regarding the wire?

Yair-
Your tables (pgs 11 & 12) should (at least) also include metric wire sizes (which I am assuming are used by most of the auto industry these days).  I know there are also Japanese wires sizes (also used by Korea).  I don't know if these show up in the auto industry.

Updates:

-Adding wire area in addition to AWG.

- Minor editorial updates

Hi All,

 

Please see attached  short summary of the above issue.

I'll appreciate any comments.
