A gas circuit breaker includes a grounded tank corresponding to each one of the plurality of phases, a bushing, an upper housing, and a lower housing, those mounted on a base that is supported by a frame. The grounded tank and the upper housing are located on a plane. The lower housing is connected to the grounded tank with a connecting unit such that the lower housing can be moved from a first position for operation lower than the plane to a second position for transportation substantially on the plane.
