*    Wire capacity limited to maximum of seven conductors due to 0.25" [6mm] material thickness of cover.

** Including one hot, neutral and ground wire from the receptacle.

*** 20% cable fill is calculated to approximate reduction in cable capacity due to connectors mounted with raceway and fittings that may restrict cross sectional area.

† 40% cable fill is the maximum designed cable based on a proposed revision to TIA/EIA 569-A.
