Conduit Capacity Chart
Important Note: This conduit capacity
chart is to be used as a general guideline.
Because local codes can vary from the
National Electrical Code, West Penn Wire
cannot be held responsible for this informa-
tion as it pertains to your installation. Proper
conduit fill is the sole responsibility of the
installer and it is your responsibility to see
that your installation will pass local codes.
* Permissible Area to be occupied (sq. in.) based on the NEC standard of 40% fill, which applies to three or more non-lead covered
cables installed in the same conduit.
