Each switching unit has a movable cart, the circuit breaker mounted on the cart, and a frame assembly. Two terminals are disposed on the back of the circuit breaker, one connected to a fixed electrode and the other connected to a movable electrode of the circuit breaker. The two terminals are connected to the communication bus and to the first or second leader bus through air bushings.
