11 July s L-11 Line and Load Terminals Line and load terminals provide wire connecting capabilities for specific ranges of continuous current ratings and wire types. All terminals comply with Underwriters Laboratories, Inc., Standards UL486A and UL486B and CSA Standard C22.2 No. 65. Unless otherwise specified, L-frame circuit breaker line and load terminals are shipped separately for fieldinstallation. Line and Load Terminals The wire connecting terminal is secured with two pan-head, slotted screws and lock washers which can be checked for the correct torque loading or retightened from the front of the circuit breaker before installation of the conductors. (Applies to all styles.) The circuit breaker line/load terminal conductors are positioned in the conducting holes in the wire connecting termi nal and are secured with recessed socket screws which are tightened to the correct torque loading from the front of the circuit breaker. Ordering Information L-frame circuit breakers use Cu/AI terminals as standard. When optional copper terminals are required, order by Catalogue number. Specify if factory installation is required.
