Gerald, Doug, et al,
For my own convenience in collecting data from multiple sources, I'll often
compile it into
humongous tables. But you are right, these large tables are not a good way to
communicate the
data via E-mail. So I've split the table in yesterday's post into:
* Nominal diameter (inches) and cross-sectional area (circular mils) for round
wires, AWG 60 to 4/0.
* Nominal resistance (milliohms/foot) for round copper wires, AWG 60 to 4/0.
* Nominal resistance (milliohms/foot) for other round wires, AWG 44 to 4/0.
