Abstract

The following specification describes a panelboard assembly comprising a plurality of modular insulators each having an integrally formed resilient bead for engaging a circuit breaker housing recess to support a circuit breaker. A tongue on each insulator assists in disengaging the circuit breaker from the bead. Longitudinally extending bus bars are supported by the insulators in heat transmitting relationship to the metal wall of an enclosure. The insulators have long surface paths between adjacent bus bars and bus stabs to prevent electrical leakage. A neutral assembly in close space saving relationship to the bus bars and for convenient wiring is provided together with partition walls between phase bus bars and between individual bus stabs.
