5 May 8 Amperes -91 Line and Load Terminals Eaton s Cutler-Hammer line and load terminals provide wire connecting capabilities for specific ranges of continuous current ratings and wire types. All terminals comply with Underwriters Laboratories Standards UL 486A and UL 486B and CSA Standard C.2 No., or Electrical Bulletin 11. Unless otherwise specified, circuit breaker line and load terminals are shipped separately for field installation. The bottom of the standard TAKB terminal contains a recess which is positioned over the circuit breaker terminal conductor. Ordering Information circuit breakers use Cu/AI terminals as standard. When optional copper-only terminals are required, order by. Specify if factory installation is required. Table Line and Load Terminals Maximum Amperes Terminal Body Material Note: No dual lugs.
