<br>
This is the reference table I was using. They show 325 AWG and
325kCM refer to the same diameter cable but I should have used kcm
for clarity. <br>
<br>
If all insulation/temp rating is the same we are back to my
original question. Anyone else able to explain this? To be safe I
am leaning toward using the combined CM number to size for current
rather than 3 times the ampacity as that just makes no sense to
me. <br>

The "area" of the conductor will be 3 times and you would think
that the NEC Ampacity would also be 3 times<br>
that of one conductor. But one LARGE conductor with the same
area might not be as high as you think<br>
because of insulation. I would think that ampacity of 3 cables
in parallel would be 3 times. But probably<br>
not when you take a single cable of the 3X area out of the NEC
table. (I haven't looked at this to verify)<br>
<br>
Also, Larry, 325 AWG 750 AWG (gauge) wire is a bit too small
for this, don't you think ?<br>
<br>
I know... You mean circular mils...<br>
