flexible conductor rating & fill

[cmonin]

Can anyone help me with allowable ampacities and conductor fill for extra flexible copper conductors? I've found the following: COBRA WIRE & CABLE X-FLEX? E NUMBER (UL) BC5W2 OR MTW OR THW FT4 OR AWM 1232/1284/1338/10070 600V OR 10269 1000V VW-1 SR AWG SIZE LL NUMBER CSA TEW 105?C 600V OR AWM I A/B 105?C 600V O FT1 ROHS COMPLIANT MADE IN USA.
Q. Where can I find, or how can I determine, conduit fill requirements for this type cable installed in EMT. This is for a 75kw (55hp) motor that has been pre-fitted for a European type cable installation. We plan to use seal tight with extra flexible conductors for motor terminations. Thanks!

I would either measure the cable or call the manufacturer and find out what the cir. mil. is of the cable.

If you scrool down the nominal OD is listed for the various sizes.

Thanks guys. We used table 4 to determine the allowable conduit space as well as solving for total conductor space by multiplying conductor radius squared by pi and adding together.

Is that compliant?
