* 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.
