ABSTRACT:
The following specification describes a panelboard assembly comprising a plurality of modular insulators having spaced integrally formed resilient mounting rails for supporting a circuit breaker housing above the panelboard bus bars. Each circuit breaker is connected to a bar carrying current of one phase and on tripping may generate ionized arc gases that exit the arc chute passage and engage a bus bar carrying current of another phase. A thermoplastic insulating material is interposed in the path between the arc chute passage and a bus bar carrying current of another phase. A bend is also introduced in the bus bars intermediate their ends to force an insulating member interposed between the bus bars and a cabinet wall against the cabinet wall.
