Control Wire Tap Lugs

Control wire tap lugs are used in applications requiring connection to a small wire (22-14 AWG) for control circuits. This is accomplished by crimping the wire to a standard wire crimp terminal (not included) and fastening the terminal to the circuit breaker lug.
Note: To order as a factory-installed device on FI, KI, LC, LI, LXI, LX or LC circuit breakers, add suffix number 8041 to circuit breaker catalog number, e.g., KIL362258041.

Power Distribution Connectors (PDC) for Circuit Breakers—for Field Replacement of Mechanical Lugs

Can be used for multiple load connections on one circuit breaker. Use in place of standard distribution blocks to save space and time.

Field-installable kits, including tin-plated aluminum connectors and all necessary mounting hardware are available for Square D FA, LA and Q4-frame molded case circuit breakers.

Connectors are UL Listed:

  • For use on load end of circuit breaker only.

  • For use in UL508 Industrial Control applications only.

  • For use in UL 1995/CSA C22.2 No. 236 heating and cooling equipment.

  • For copper wire only.

Footnotes

  1. Unless otherwise specified, wire sizes apply to both aluminum and copper conductors.
  2. For use in the OFF end only, when the OFF end is the load end.
  3. Use suffix 8002 for factory-installed Cu lugs.
  4. Use fully-insulated 0.250 inch slip-on connectors.
  5. See instruction bulletins for recommended tools.
  6. These lug kits cannot be used on I-Line™ circuit breakers.
  7. All P-frame circuit breakers require terminal pads for mounting lugs of any type.
  8. Not for use with I-Line circuit breakers.
  9. When using fine stranded wire, increased cross sectional area may cause maximum wire size to be reduced.
  10. OFF end only when OFF end is the load end.
