* 75C wire (higher temperature rated wire acceptable with appropriate derating). Using a ferrule on a stranded conductor requires a correctly sized UL Listed ferrule (customer supplied) applied according to the manufacturers specifications. Ferrule ratings apply to copper wire only.
See Short-Circuit Current Ratings table for the tested upstream overcurrent protective devices necessary for achieving these SCCRs.
Torque rating for dual wire and ferrule application is 30.5 Nm (270 Lb-in).
Configuration includes hex screws.
