Torque requirements

The LINE, LOAD and NEUTRAL lugs that are provided in the D325NTR, Series E1 safety switch are suitable for use with either (1) #1 AWG - 600 KCMIL or (2) #1/0 AWG - 250 KCMIL wires. However, the available wire bending space provided in the switch restricts the use to (2) #1/0 AWG - 250 KCMIL. When using this configuration, the wire binding screw should be torqued to 340 Lb- In. The service ground lug is suitable for (1) #1 - 4/0 AWG conductor and should be torqued to 180 Lb-In. This information is documented on the wiring diagram of the switch, which is located on the rear of the front cover.
