A circuit breaker (10) including a stationary line bus assembly (47). The stationary line bus assembly (47)comprises a bus body (124) supported by support legs (132) with the bus body (124) having a first longitudinal end portion (125) and a second longitudinal end portion (126), with each end portion terminating at a common end portion (127). The second end portion (126) includes a stationary contact bus (46) in a spaced relationship from the first end portion (125). A line terminal (18) is mounted on the first longitudinal end portion (125) and a contact (44) is attached to the second longitudinal end portion (126). In one embodiment, a bus support (130) is attached to the bus body (124) in the space between the first end portion (125) and the second end portion (126) and separated from the support legs (132) of the bus body (124) by an insulating barrier (134). The stationary bus support (130) can have several configuration.
