Abstract
Line and load lugs are fixedly attached to each pole of a multi-pole molded case circuit breaker without requiring screws. The lugs are positioned within the line and load lug compartments at opposing ends of the breaker by grooves formed along the sides of the lugs and rails formed within the internal surfaces of the compartments. A lug support cap fitted to the bottom of each line and load lug interacts with detents formed on the inner surfaces of the compartments to securely retain the line and load lugs within the compartments.
