typical motor winding configurations.
Line Connected Soft Starter Power Wiring Diagram
The following table lists the maximum wire sizes and number of conductors required per
phase for mechanical and compression type lugs. Due to difficulties bending large diameter
conductors, the maximum single conductor gauge is limited to 350 kcmil.
Power terminal wire connectors are not shipped with the product. To maintain the agency
certifications/listings, Eaton recommends using the wire connectors (lugs) in the table below.
Customers may select lugs that are commercially available and suitable for use, from industry
standard sources that meet the general specifications in the table below. Refer to Appendix D
for alternate lug cross reference tables.
Note: When securing the lugs onto the bus bars of the soft starters, use a suitable tool such
as another wrench to counteract the bolt torque and prevent excessive side loads
being placed on the supports.
