About Flat Cable

KwikLink flat cable is physically keyed to prevent wiring mishaps.
KwikLink cable is available in both heavy-duty and general purpose
versions. All variations of KwikLink cable are unshielded and contain four
conductors. Flat cable is used exclusively for the trunk line.

Class 1 (CL1) Heavy-duty Cable: Per NEC specifications for a Class 1
circuit (see Appendix A), the power source must have a rated output of less
than 30V and 1000VA. Based on the size of the flat cable conductors, the
maximum current through the network must be no more than 8A. Class 1
KwikLink cable is UL listed for 600V and 8A at 24V dc. Use Class 1 drops in
conjunction with Class 1 flat cable.

Class 2 (CL2) Heavy-duty Cable: More flexible than the CL1 cable, this
design adheres to NEC Article 725, which states that for a Class 2 circuit, the
power source must have a rated output of less than 30V and 100VA. In the
case of DeviceNet, running at 24V, the maximum allowable current is
100VA/24V or 4A. KwikLink CL2 cable is rated to 4A at 24V dc.
