Circuit breaker support saddle with removable phase barriers

Claim 1

A modular phase barrier assembly including a molded plastic circuit breaker support saddle comprising: a molded plastic circuit breaker support saddle having insulative phase barrier members thereon supporting main bus conductors and branch strap conductors; each phase barrier member comprising a molded plastic support defining a top surface, a bottom surface and a pair of opposing ends, said plastic support having access means through both of said surfaces for passage of a molded case circuit breaker connector stab; a plurality of planar walls integrally formed within said plastic support and extending upwards from said top surface to provide electrical insulation between a plurality of branch strap conductors when mounted on said top surface; a plurality of post means integrally formed within said plastic support for guiding and supporting said branch strap conductors on said top surface; rail means integrally formed within said plastic support and extending from said bottom surface and attaching said plastic support to corresponding support track means extending from a top surface of said plastic circuit breaker support saddle, said rail means and said track means further provide electrical insulation between said main bus conductors and said branch strap conductors; and a step integrally formed at one of said support ends for receiving an end integrally formed in a separate plastic support whereby a plurality of said plastic supports and said separate plastic supports can be abuttingly assembled together on said plastic circuit breaker support saddle.
