1. Cross-sectional area reduced due to 40N2F55 C-Box.
2. No. of conductors are reduced when using both channels for power.
3. 20% cable fill calculated to approximate reduction in cable capacity due to connectors
mounted within raceway and fittings that may restrict cross-sectional area.
4. 40% cable fill is the maximum designed cable fill based on TIA/EIA 569-A.
