*Note: Wire size specifications for conductors are listed as AWG or kcmil. For stranded conductors, the use of ferrules requires a correctly sized UL Listed ferrule applied according to manufacturer specifications. Ferrule ratings apply to copper wire only. Torque values are in Nm (Lb-in). SCCR values are dependent on the application of an upstream current-limiting overcurrent protective device. See Short-Circuit Current Ratings table for specific fuse requirements.
