Pole unit guide

摘要

A guide assembly for a switchgear assembly is provided. The guide assembly includes an elongated support member and a passage. The support member is coupled to and extends from a housing assembly rear sidewall. The support member extends in the circuit breaker assembly direction of travel. The passage is disposed on the circuit breaker assembly base and also extends in the circuit breaker assembly direction of travel. The support member is substantially aligned with the passage. In this configuration, as the circuit breaker assembly moves between a withdrawn position and an installed position, the support member moves between a first position, wherein the support member is not disposed in the passage, and a second position, wherein the support member is partially disposed in the passage. When the support member is in the second position, the support member bears a portion of the weight of the circuit breaker assembly base.
