A circuit breaker has ferrule type line and load terminals which clip on to portions of, respectively, input and output current buses for the breaker to permit the breaker by a mere plug-in action to be fastened to those two buses. The output current bus is provided by an adapter comprising a molded plastic case having at its top a receptacle for an end lug on a cable for distributing current from the breaker to a load, and having at its bottom a cylindrical metallic contact to which the load terminal of the breaker is or may be clipped. A metallic bus strap extends in the case from that contact to terminal means in the receptacle for connecting the upper end of the strap to such lug. The case has formed on the outside thereof a horizontal guideway into which the input current bus may be slid to thereupon be held insulated from, and fixedly fastened with, the output current bus strap in the adapter.
