ABSTRACT:
A circuit breaker structure characterized by a multi-pole circuit breaker which is adapted for quick removal and/or replacement of a circuit breaker having at least two horizontally spaced poles, each pole comprising two vertically spaced incoming and outgoing terminals or disconnecting contact assemblies, each terminal comprising a plurality of horizontally spaced terminal members or fingers which are vertically disposed, the terminals being adapted to connect with a plurality of spaced incoming and outgoing bus conductors comprising upper and lower sets of conductor members or fingers which are interengageable with the terminal fingers of the corresponding terminals, each set of upper and lower incoming and outgoing terminals having aligned apertures, each set of upper and lower incoming and outgoing conductor fingers having aligned slots, a first insulated bolt and nut assembly extending through the aligned apertures of the upper set of terminal fingers and having insulating spacers between horizontally spaced terminals, and a second insulated bolt and nut assembly extending through the apertures of the lower set of terminal fingers and having insulating spacings between each terminal, whereby upon tightening of the bolt and nut assembly, the terminal fingers and conductor fingers are retained in tight electrically conductive surface-to-surface contact with each other.
